8A5DBB36FFB32910FC54F955FB0CFA50.taxon	discussion	NOTES Cryptosphaeria Ces. & De Not. was introduced by Greville (1822). Taxonomic significance of this genus remained unclear as the original author incorporated a number of disparate taxa under this genus viz. Botryosphaeria species, due to some morphological similarities such as ascostromata characters (Rappaz 1987). Cesati & De Notaris (1863) re-used the name Cryptosphaeria and designated Cryptosphaeria millepunctata as the type species, although Cr. eunomia, is now the widely accepted name for the type (Clement & Shear 1931). Cryptosphaeria Ces. & De Not. (1863) has been adopted in favour of Cryptosphaeria Grev. (Rappaz 1989). Cryptosphaeria species produce 8 - spored, spindle-shaped asci with long stipitate and subolivaceous to brown ascospores (Glawe & Rogers 1984; Rappaz 1987; Trouillas et al. 2011). This genus comprises 13 species of which Cr. eunomia and Cr. mangrovei have been reported as saprobes from marine habitats (Trouillas et al. 2015; Jones et al. 2015). Recently, Cr. mangrovei has been synonymized with Halodiatrype mangrovei, based on morphological characteristics (Dayarathne et al. 2016) (see description and illustration under Halodiatrype mangrovei. Currently, combined ITS (ITS 1, 5.8 s and ITS 2 regions) and Btub gene sequence data coupled with morphological characteristics are used to differentiate Cryptosphaeria species (Acero et al. 2004, Trouillas et al. 2010 a). Our phylogenetic analyses showed that Cryptosphaeria is polyphyletic, as reported by Shang et al. (2017) and Senwanna et al. (2017).	en	Dayarathne, Monika C., Wanasinghe, Dhanushka N., Devadatha, B., Abeywickrama, Pranami, G, E. B., Jones, areth, Chomnunti, Putarak, Sarma, V.

8A5DBB36FFB2290CFC4AF9D6FE52FE8C.taxon	discussion	NOTES Cryptosphaeria avicenniae Devadatha & V. V. Sarma, sp. nov., has a wide, white line under the black hymenium in the ascomata, which is akin to Cr. bathurstensis (synonym of Eutypa bathurstensis). Cryptosphaeria avicenniae Devadatha & V. V. Sarma, sp. nov., and Cr. bathurstensis have similar morphological characteristics with overlapping dimensions of the ascomata (300 - 585 × 200 - 700 vs 300 - 600 × 800 µm) and ascospores (5 - 13 × 1.5 - 3 vs 6 - 12 × 2 - 2.8 µm). Cryptosphaeria avicenniae Devadatha & V. V. Sarma, sp. nov., has shorter necks and light brown ascospores when compared to Cr. bathurstensis (100 - 350 µm vs 500 µm). Cryptosphaeria avicenniae Devadatha & V. V. Sarma, sp. nov., has larger asci bearing spore part (50 - 95 × 7 - 14 µm), light brown ascospores, and found on Avicennia marina. Cryptosphaeria bathurstensis (K. D. Hyde & Rappaz) Dayarathne & K. D. Hyde, comb. nov., has smaller asci bearing spore part (30 - 50 × 8 - 10 µm), olive-brown ascospores and is known on branches of Avicennia sp. located in the upper intertidal region. Unfortunately, the type of Cr. bathurstensis lacks sequence data for a comparison. Halodiatrype avicenniae is obviously distinct from Cryptosphaeria avicenniae Devadatha & V. V. Sarma, sp. nov., in having deeply immersed smaller ascomata in a darkened pseudostroma and larger asci and ascospores. Morphological similarities that Cr. avicenniae Devadatha & V. V. Sarma, sp. nov., has with other Cryptosphaeria species are the widely effuse and poorly developed stromata, spindle-shaped, long-stipitate asci with light brown ascospores. Multigene phylogenetic analyses of combined datasets of ITS + Btub and ITS showed that Cr. avicenniae Devadatha & V. V. Sarma, sp. nov., nested with Cryptosphaeria species. Cryptosphaeria avicenniae Devadatha & V. V. Sarma, sp. nov., showed a sister relationship with Cr. pulmanensis, Cr. ligniota and Cr. subcutanea with moderate statistical support (ITS + Btub = 60 % ML, 0.94 PP) (ITS = 60 % ML, 0.95 PP) (clade F in Fig. 1, clade N in Fig. 2). Morphologically Cr. avicenniae Devadatha & V. V. Sarma, sp. nov., is distinct from Cr. ligniota and Cr. pulmanensis in having light brown ascospores containing oil droplets whereas Cr. ligniota have pale yellow ascospores and Cr. pulmanensis have brown ascospores and by occurring in a marine habitat. Cryptosphaeria ligniota, Cr. pullmanensis and Cr. subcutanea are specific to their host plants in Salicaceae (Populus and Salix spp.) from terrestrial habitats (Rappaz 1987). Ascospores of Cryptosphaeria species are distinct: Cr. pullmanensis with oblong to reniform, occasionally septate, brown ascospores; Cr. subcutanea allantoid to cylindrical, brown ascospores; Cr. ligniota allantoid, pale yellow ascospores. Cryptosphaeria ligniota and Cr. subcutanea have J + asci, while the other species discussed in this paper have J- asci. Hence, a new species Cr. avicenniae Devadatha & V. V. Sarma, sp. nov., is introduced based on both morphological and phylogenetic analysis. The asexual morph of Cr. avicenniae Devadatha & V. V. Sarma, sp. nov., is similar to the anamorph reported for Diatrypaceae members, with filiform, hyaline conidia that are straight or curved with blunt ends.	en	Dayarathne, Monika C., Wanasinghe, Dhanushka N., Devadatha, B., Abeywickrama, Pranami, G, E.

8A5DBB36FFAE290CFF3FFE92FA00F9D0.taxon	discussion	NOTES Cryptosphaeria bathurstensis (K. D. Hyde & Rappaz) Dayarathne & K. D. Hyde, comb. nov., was first collected on branches of Avicennia located in the upper intertidal region, inundated by seawater for several days each month at Bathurst Heads, northeast Queensland. This (and an unidentified Eutypa and Eutypella) was the first species of Diatrypaceae collected in such an “ unusual habitat ” (Hyde & Rappaz 1993). It is unusual amongst the Diatrypaceae in possessing a thick, hyaline wall under the hymenium (Hyde & Rappaz 1993). The wall comprised three strata: subhymenial, median, and external layers. Hyde & Rappaz (1993) described the presence of numerous crystals in middle and outermost layers, which were interspersed with the peridium cells, but we did not observe this in our study. Hyde & Rappaz (1993) described the asexual morph of Cryptosphaeria bathurstensis (K. D. Hyde & Rappaz) Dayarathne & K. D. Hyde, comb. nov., as hyaline, filiform conidia in axenic cultures, which were similar to those previously described within the Diatrypaceae (Glawe & Rogers 1982, 1986; Rappaz 1987). Our morphological studies showed that this species is similar to Cryptosphaeria species, comprises exclusively corticolous species of the Diatrypaceae, with widely effuse and poorly developed stromata that often are covered by the periderm, which is penetrated only by the separately emerging ostioles. Asci are generally spindle-shaped, long-stipitate, with subolivaceous to brown ascospores (Glawe & Rogers 1984; Rappaz 1987). This species also resembles Halodiatrype species in lacking stromatic tissues and ascospore morphology. However, ascomata of Halodiatrype species are deeply immersed in a darkened pseudostroma while stromata of Cryptosphaeria bathurstensis (K. D. Hyde & Rappaz) Dayarathne & K. D. Hyde, comb. nov., are immersed but blackening the wood surface with a poorly developed entostroma. Cryptosphaeria bathurstensis (K. D. Hyde & Rappaz) Dayarathne & K. D. Hyde, comb. nov., lacks the unique characteristics of Eutypa species, such as welldeveloped stromata, flask-shaped ascomata, scattered evenly in to a single layer just beneath the surface, often prominent sulcate ostioles or ostioles that are distinctly beaked, black, sometimes ornamented with radial furrows and hyaline or yellowish ascospores (Wehmeyer 1975; Glawe & Rogers 1984). Cryptosphaeria avicenniae Devadatha & V. V. Sarma, sp. nov., grouped with Cryptosphaeria species in our phylogenetic analyses. Considering the above morphological observations and phylogenetic placement of other morphologically related species we transfer Eutypa bathurstensis to the genus Cryptosphaeria.	en	Dayarathne, Monika C., Wanasinghe, Dhanushka N., Devadatha, B., Abeywickrama, Pranami, G, E.

8A5DBB36FFAE290AFC30F955FA0FF911.taxon	discussion	NOTES Cryptosphaeria eunomia possesses a widely effused stroma within bark tissues that is slightly elevated, light colored or darkened, with separate, rounded or stellate ostioles at the surface. Asci are clavate or cylindrical, 8 - spored, usually with long stalks, and paraphysate with allantoid, hyaline or brownish ascospores. It is widely known from Fraxinus spp., Juglans regia, and Robinia pseudoacacia (Rappaz 1987; Grand 1985; Dudka et al. 2004; Farr & Rossman 2018). It has also been isolated from an unidentified marine sponge from Pohnpei, and which yielded the anti-mycobacterial compounds diaporthein A and B (Kim 2013). Unfortunately, we were unable to obtain herbarium material of Cryptosphaeria eunomia collected from a marine habitat and there are no sequences generated from marine based strains. We used two strains of Cr. eunomia var. eunomia (CBS 216.87) and Cr. eunomia var. fraxini (CBS 223.87) in our phylogenetic analyses. They grouped apart from all other Cryptosphaeria species and were located in a clade comprising Eutypa species (Figs 1; 2).	en	Dayarathne, Monika C., Wanasinghe, Dhanushka N., Devadatha, B., Abeywickrama, Pranami, G, E.

8A5DBB36FFA82909FC70F915FB53FAB3.taxon	discussion	NOTES Cryptosphaeria halophila Dayarathne & K. D. Hyde, sp. nov., is the first record of an asexual morph in this genus, reported from a marine habitat. Libertella - like asexual morphs have been reported from host substrates and axenic cultures in previous studies by Trouillas et al. (2015) and Mehrabi et al. (2016). In our phylogenetic analyses (ML and BI) with combined SSU + LSU sequence data, this species grouped with Cr. ligniota and Cr. pullmanensis as a separate lineage, but with poor bootstrap support (Fig. 3). MP results showed that this novel species nested with Cryptosphaeria avicenniae Devadatha & V. V. Sarma, sp. nov., with no support (Fig. 4). The asexual morph of Cryptosphaeria avicenniae Devadatha & V. V. Sarma, sp. nov., is similar to Cryptosphaeria halophila Dayarathne & K. D. Hyde, sp. nov., and Halocryptovalsa avicenniae, comb. nov. (synonym of Cryptovalsa avicenniae) in conidiomatal and conidial morphology. However, our phylogenetic analyses showed that they are phylogenetically distinct (Figs 3 - 4). No cultures were obtained for this species since conidia did not germinate on any culture media used (WA, MEA / PDA, seawater MEA / PDA or CMA). We did not obtain ITS and Btub sequence data for this species by direct sequencing of fresh fruiting bodies, after several attempts with different temperature profiles. Hence, further taxon sampling, isolation and sequence data are required to further confirm phylogenetic placement of this taxon within this genus.	en	Dayarathne, Monika C., Wanasinghe, Dhanushka N., Devadatha, B., Abeywickrama, Pranami, G, E.

8A5DBB36FFAB2909FC09FAB7FAE6F851.taxon	discussion	NOTES Cryptovalsa contains 24 species, which are reported on woody substrates in a wide range of terrestrial habitats (Wijayawardene et al. 2017). The generic type, Cryptovalsa protracta lacks sequence data in GenBank (Abdel-Wahab et al. 2017). Four Cryptovalsa species have been described from marine habitats namely, C. avicenniae, C. halosarceiicola, C. mangrovei, C. suaedicola (Spooner 1981, Inderbitzin et al. 1999, Abdel-Wahab et al. 2017). However, based on morphological and phylogenetic data C. avicenniae is transferred to the new genus, Halocryptovalsa Dayarathne & K. D. Hyde, gen. nov. Cryptovalsa is in need of further revision, with detailed modern descriptions, and better illustrations of species, their epitypification, isolation and sequencing to establish phylogenetic relationships to other genera in the family (Abdel-Wahab et al. 2017).	en	Dayarathne, Monika C., Wanasinghe, Dhanushka N., Devadatha, B., Abeywickrama, Pranami, G, E.

8A5DBB36FFAA2908FEA6FCD1FB47FA10.taxon	description	DESCRIPTION Sexual morph Ascomata. Flask-shaped, black, immersed in a wide-spreading entostroma in the surface layers of the host tissue, with protruding necks, of dark angular cells, with periphyses. Substratum blackened around the ascomata, with a depressed zone between them (seen in section). Peridium. Comprising an inner layer of hyaline elongate cells, and an outer layer of dark fungal hyphae in the form of textura intricata, fusing at the outside with the host tissue. Paraphyses. Hyphae-like, filamentous, numerous. Asci. Polysporous, cylindric-fusoid, tapering to the peduncle, tapering in the upper part to a truncate thickened apex, with a faint, non-amyloid subapical ring. Ascospores. Allantoid, non-septate, hyaline (Description from Hyde 1993). Asexual morph Undetermined. NOTES Cryptovalsa halosarceiicola was associated with the mangrove fungus Marinosphaera mangrovei (Hyde 1993). It can be distinguished by the flask-shaped ascomata immersed in a wide-spreading entostroma with protruding necks, hyphae-like filamentous paraphyses, polysporous asci with non-amyloid subapical ring and allantoid, hyaline ascospores (Hyde 1993). No ascomata of Cryptovalsa halosarceiicola were present in the type material of the species. Therefore, it is in need of epitypification for future studies. Cryptovalsa halosarceiicola is morphologically similar to C. suaedicola but differs in ascomatal characteristics such as the longer neck lacking furrows, and a two-layered thick peridium. Cryptovalsa halosarceiicola, Halocryptovalsa avicenniae, comb. nov., and the novel species Halodiatrype salicorniae share similar morphologies in ascomatal and ascal characteristics. Cryptovalsa halosarceiicola and Halodiatrype avicenniae are easy to differentiate by ascospore colouration, which is yellow-brown to brown in Halodiatrype avicenniae and hyaline in Cryptovalsa halosarceiicola. However, the ascomatal measurements of these two species are considerably disparate (Table 4). There are no molecular data for these species to confirm their phylogenetic affinity with other related taxa within the family.	en	Dayarathne, Monika C., Wanasinghe, Dhanushka N., Devadatha, B., Abeywickrama, Pranami, G, E.

8A5DBB36FFAA2906FCF9FA16FCA6F910.taxon	description	DESCRIPTION Sexual morph Saprobic. On in decorticated wood test blocks of Kandelia candel. Ascomata. In groups of 3 - 8, sometimes confluent, in 1 - 3 rows, immersed, raising the substratum, or erumpent. Entostroma. Effuse, a faint black line between the groups sometimes present, wood softened; a thin layer of white pulvinate fungal material sometimes present around the ascomal venter. Ascomal venter. 250 - 278 µm high, 245 - 352 µm wide, subglobose to broadly ellipsoidal. Necks. 208 - 220 µm long, 180 - 190 µm wide, ostiolate, periphysate, comprising an outer layer of completely melanized cells, and an inner layer of less pigmented, elongate cells; singly erumpent, protruding above the level of the raised substratum; the outermost ascomata in an aggregate often bent towards the centre of the group, with four narrow furrows on the dome shaped apex. Peridium. 10 - 25 µm wide, in horizontal section with an outer, layer of small, thick-walled, melanized, rounded cells, and an inner layer, up to 12 µm wide, of hyaline, elongate cells in textura angularis. Paraphyses. Up to 3 - 4 µm wide, hyaline, septate, deliquescent. Asci. 80 - 150 × 10 - 14 µm (ẍ = 115 × 12 µm, n = 20), polysporus, clavate, truncate, pedicellate; apex up to 3.5 µm thick, with a refractive subapical, non-amyloid ring at the base of an invagination of the ascus apex. Ascospores. 5 - 14 × 1 - 3 µm (ẍ = 10 × 2 µm, n = 30), allantoid, pale yellow to pale brown. Asexual morph Undetermined. NOTES Cryptovalsa mangrovei possesses single or eutypa-like ascomata with polysporous asci (Spooner 1981) which are characteristics of the genus Cryptovalsa. Cryptovalsa mangrovei differs from C. halosarceicola and C. suaedicola by its larger ascomata, asci and ascospores, clavate asci, horizontally furrowed necks, pigmented ascospores and deliquescent paraphyses. There is no blackened zone around the ascomatal venters of C. mangrovei, which is present in C. halosarceicola and C. suaedicola (Table 4) (Spooner 1981; Inderbitzin et al. 1999). Halocryptovalsa avicenniae, comb. nov., and the novel species Hcr. salicorniae lack horizontal furrows inside their ascomatal necks and hence are distinguishable from C. mangrovei. Further taxon sampling is needed for this species to obtain appropriate molecular data to substantiate its placement within a natural classification system.	en	Dayarathne, Monika C., Wanasinghe, Dhanushka N., Devadatha, B., Abeywickrama, Pranami, G, E.

8A5DBB36FFA42906FE8FF915FB69F851.taxon	description	DESCRIPTION Sexual morph Stromata. 0.9 - 1.5 mm diam., well developed, visible as black spots on host surface, substratum blackened around the stromata and with a depressed zone between them. Ascomata. 370 - 350 × 290 - 350 µm, flask-shaped, immersed, 1 - 3 within one stroma, evenly scattered in a single layer in a widespread entostroma in the surface layers of the host tissue, black, the ostioles protruding and bearing 4 vertical furrows. Peridium. 35 - 40 µm wide, composed of 8 - 9 layers of prismatic cells, the outermost cells dark brown and thick walled, becoming paler inwards. A thickened ring of tissue composed of thick walled dark brown cells is present immediately below the ostiolar neck. Paraphyses. 1 - 2 µm wide, filiform, usually branched, hyaline, containing a row of small guttules. Asci. 80 - 130 × 6 - 7.5 µm (ẍ = 105 × 6.5 µm, n = 20), cylindric-fusoid, tapered in the upper part to a rounded apex, and below to a narrow, stipe-like base, rather thickwalled above, apical apparatus diffusely and weakly amyloid, polysporous. Ascospores. 4 - 6 × 1 - 1.5 µm (ẍ = 5 × 1 µm, n = 30), allantoid, non-septate, individually appearing hyaline but greenish in mass within the ascus. Asexual morph Undetermined. NOTES Cryptovalsa suaedicola reported from temperate Suaeda occurred on twigs associated with lichens and probably occurred above the intertidal region (Spooner 1981). The species is unique by the wide-spreading eutypoid ascostroma, separate, immersed perithecia with a neck bearing four vertical furrows and polysporous asci. However, C. effusa on stems of Rosa canina in Europe (Berlese 1905) appears very similar to this species in possessing solitary perithecia. Cryptovalsa suaedicola differs particularly in possessing larger ascospores from other marine Cryptovalsa species (Spooner 1981). Four vertical furrows of the ascomatal neck is the most useful characteristic to differentiate this species from all other morphologically similar diatrypaceous species from marine based habitats, such as, C. halosarceicola, C. mangrovei, Halocryptovalsa avicenniae, comb. nov., and Hcr. salicorniae (Table 4). Lack of sequence data for this species may lead to taxonomic confusion when determining whether to accommodate this species within the new genus Halocryptovalsa Dayarathne & K. D.

8A5DBB36FFA62902FF0CFAD7FEEEFB33.taxon	discussion	NOTES Diatrype mangrovei Dayarathne & K. D. Hyde, sp. nov., was recorded from intertidal attached wood of Bruguiera cylindrica from Ranong, Thailand. In the phylogenetic analyses of both ITS and concatenated ITS + Btub data (Figs 1; 2) it grouped in a clade with Diatrype and Diatrypella species. Diatrype mangrovei Dayarathne & K. D. Hyde, sp. nov., shares similar morphological features with the genus Diatrype and is distinguished from Diatrypella species by being octosporous. Diatrype enteroxantha (HUEFS 155114, HUEFS 155116) showed close phylogenetic affinity to this new species (subclade A 4 in clade A, Fig. 1) but D. enteroxantha has smaller asci (18 - 28.5 × 5 - 9 µm vs 90 - 120 × 6 - 8 µm) (de Almeida et al. 2016). There are 14 bp differences out of 520 bp (2.69 %) between D. enteroxantha and D. mangrovei Dayarathne & K. D. Hyde, sp. nov., According to ITS phylogeny, D. mangrovei Dayarathne & K. D. Hyde, sp. nov., formed an intermediate clade (sub-clade L 4 in clade L) to D. enteroxantha and D. oregonensis (DPL 200) (Fig. 2). Diatrype mangrovei Dayarathne & K. D. Hyde, sp. nov., is easily distinguishable from D. oregonensis by having globose to sub-globose ascomata while the latter species has ovoid or ellipsoid ascomata with a white entostroma that becomes yellow to brown (Trouillas et al. 2010 a). However, there are 16 bp are differences out of 526 bp (3.04 %) in ITS region between D. oregonensis and D. mangrovei Dayarathne & K. D. Hyde, sp. nov., Morphological differences of D. mangrovei Dayarathne & K. D. Hyde, sp. nov., and related taxa are summarized in the Table 5.

8A5DBB36FFA02901FC4AF915FD9DFBB2.taxon	discussion	NOTES Eutypella was introduced by Saccardo (1875) with Eutypella cerviculata (Fr.) Sacc. as type species. Eutypella species can be distinguished by their erumpent ascostromata through the host bark, clustered, sulcate perithecial necks, 8 - spored, clavate asci with long stalks and allantoid, hyaline or yellowish ascospores (Glawe & Rogers 1984; Vasilyeva & Stephenson 2006). Croxall (1950) provided an account of the asexual morph of Eutypella with conidia produced from phialides. Glawe & Rogers (1982) described some asexual morphs of Eutypella producing holoblastic conidia from sympodial or percurrently proliferating conidiogenous cells, but not from phialides. Morphologically Eutypa and Eutypella species are hard to differentiate from each other. Hence, Tiffany & Gilman (1965) classified Eutypella species under the name Eutypa (Vasilyeva & Stephenson 2009). Eutypella species occur on a wide range of hosts, especially associated with canker diseases in Vitis vinifera (Vasilyeva & Stephenson 2006; Trouillas et al. 2011; Luque et al. 2012). There are 248 species epithets listed in Index Fungorum (2019), but few species have sequence data. Phylogenetic analyses of Diatrypaceae have shown that Eutypella is polyphyletic (Acero et al. 2004; Chacón et al. 2013; de Almeida et al. 2016; Shang et al. 2017; Senwanna et al. 2017). Most Eutypella strains exhibit large differences in the length of ITS 1 region, in some cases with a different distribution of the tandem-repeat sequences. This was the most heterogeneous group at the sequence level within family Diatrypaceae (Acero et al. 2004).	en	Dayarathne, Monika C., Wanasinghe, Dhanushka N., Devadatha, B., Abeywickrama, Pranami, G, E.

8A5DBB36FFA32900FB82FC70FA92FCAD.taxon	discussion	NOTES Halocryptovalsa Dayarathne & K. D. Hyde, gen. nov., comprises cryptovalsa-like marine based diatrypaceous fungi with poorly developed stromata that lack horizontal or vertical furrows within the ascomatal necks. Halocryptovalsa Dayarathne & K. D. Hyde, gen. nov., can be clearly distinguish by having deeply immersed perithecia in the wood with relatively long, wide necks (290 - 430 µm long, 270 - 290 µm wide) while Cryptovalsa mostly comprises several ascomata arranged at different depth in the bark with relatively short necks (Mehrabi et al. 2015). Necks of each ascoma of Halocryptovalsa Dayarathne & K. D. Hyde, gen. nov., appear as a small papilla protruding above the substrate, whereas protruding ascomatal necks of Cryptovalsa form a cluster of little bumps (Mehrabi et al. 2015; Trouillas et al. 2015). Furthermore, the ascomatal outer surface of Cryptovalsa species is often with a white powdery entostroma (Trouillas et al. 2015), while Halocryptovalsa Dayarathne & K. D. Hyde, gen. nov., species do not have a white powdery entostroma. Halocryptovalsa Dayarathne & K. D. Hyde, gen. nov., includes only marine derived taxa while Cryptovalsa species are prevalent in terrestrial habitats. Cryptovalsa halosarceiicola morphologically resembles Halocryptovalsa Dayarathne & K. D. Hyde, gen. nov., species, however, there are no sequence data in GenBank for Cryptovalsa halosarceiicola to confirm its phylogenetic relationship to our new genus. In our combined analysis of ITS + Btub the new genus formed a separate lineage with low statistical support (Fig. 1). In ITS phylogeny Halocryptovalsa avicenniae, comb. nov., grouped in a clade with Diatrypasimilis australiensis (Fig. 2). However, 117 bp are different out 522 bp between Halodiatrype avicenniae and D. australiensis in ITS loci. Therefore, depending on the combined phylogenetic analyses data and considerable morphological differences of this taxon to all the other genera in Diatrypaceae, we introduce the genus Halocryptovalsa Dayarathne & K. D. Hyde, gen. nov., to accommodate Halocryptovalsa avicenniae, comb. nov., and Halocryptovalsa salicorniae Dayarathne & K. D.

8A5DBB36FFA2293EFC4FFCB0FED8FD0D.taxon	discussion	NOTES Halocryptovalsa avicenniae, comb. nov. (synonym of Cryptovalsa avicenniae) and its asexual stage (libertella-like) is kown from Avicennia marina from Australia and on driftwood from Saudi Arabia (Abdel-Wahab et al. 2017). This species morphologically resembles Cryptovalsa species as well as the new species, Halocryptovalsa salicorniae Dayarathne & K. D. Hyde, sp. nov. Halocryptovalsa avicenniae, comb. nov., has larger ascomata than other members of Diatrypaceae, lacks papillial furrows on the ascomata and has more ascospores per ascus (Abdel-Wahab et al. 2017). Therefore, it can be clearly distinguished from the previously described marine species, Cryptovalsa halosarceiicola, C. mangrovei and C. suaedicola. The presence of the asexual stage (libertellalike) in the same stroma is characteristic of this species. Morphological variation between Hcr. avicenniae and Hcr. salicornia e are compared in Table 4. Halocryptovalsa Dayarathne & K. D. Hyde, gen. nov., species do not form a stable position in our phylogenetic study. In our phylogenetic analyses with combined ITS + Btub neither Cryptovalsa rabenhorstii strains nor any other Cryptovalsa species grouped with Halocryptovalsa Dayarathne & K. D. Hyde, gen. nov., species, confirming Halocryptovalsa Dayarathne & K. D. Hyde, gen. nov., and Cryptovalsa as phylogenetically distant. Halocryptovalsa avicenniae, comb. nov., lack of ITS and BTUB sequence data in the GenBank. Therefore, we conducted a separate phylogenetic study with combined 18 S and 28 S rDNA sequences by including both Hcr. avicenniae and Hcr. salicorniae with selected diatrypaceous species following Abdel-Wahab et al. (2017) (Figs 3; 4). According to our second phylogenetic analyses of 18 S and 28 S rDNA sequences, Halocryptovalsa avicenniae, comb. nov., strains formed a single clade with Hcr. salicorniae. Hence, by considering both morphological and phylogenetic affinities we accomadated these two species under the newly introduced genus Halocryptovalsa Dayarathne & K. D.

Hyde, sp. nov., proved their conspecificity and placement in Diatrypaceae as a separate species from all other genera (clade J) (Figs 1; 2). According to our phylogenetic analyses with ITS and combined ITS + Btub, stability of this genus within the family needs to be re-considered with more taxon sampling as taxa grouped in different positions. Our second analysis with LSU + SSU sequence data confirmed its phylogenetic relationship to Halocryptovalsa avicenniae, comb. nov. (Figs 3; 4). Morphologically, they differ in length and colour of ascospores (5 - 8 µm, yellow-brown to brown in Hcr. avicenniae and 3 - 5 µm, hyaline in Hcr. salicorniae). Because Halocryptovalsa avicenniae, comb. nov., and Hcr. salicornia e and distantly placed from Cryptovalsa species, we accommodated these species in a new genus Halocryptovalsa Dayarathne & K. D.

Halodiatrype salinicola is distinguish from H. avicenniae by having unique ascomatal characters and apex composed of brown outer amorphous layer and inner yellow cells of textura porrecta and aseptate ascospores becoming 1 - septate at maturity.

However, our phylogenetic survey proved that this species is phylogenetically distantly placed from Cryptosphaeria, as reported by Dayarathne et al. (2016). Two strains of H. salinicola and strains of H. avicenniae formed a well-separated clade from all other genera in Diatrypaceae with high bootstrap support (99 % ML / 90 % MP / 1.00 PP).	en	Dayarathne, Monika C., Wanasinghe, Dhanushka N., Devadatha, B., Abeywickrama, Pranami, G, E.

8A5DBB36FF9E293AFC7FF9D6FE02FA50.taxon	discussion	NOTES Cryptosphaeria mangrovei, which was reported from dead roots of Rhizophora apiculata in intertidal mangroves in Thailand (Hyde 1993) is characterized by clavate, extremely thin-walled, slightly truncate asci, with an indistinct apical thickening, lacking an apical ring, and with allantoid or subinequilateral, one-celled guttulate ascospores. This species is similar to species of Halodiatrype in having allantoid or subinequilateral, light brown ascospores and was collected from intertidal mangrove on dead roots of Rhizophora apiculata (Rhizophoraceae). Therefore, we make the new combination of Halodiatrype mangrovei.	en	Dayarathne, Monika C., Wanasinghe, Dhanushka N., Devadatha, B., Abeywickrama, Pranami, G, E.

8A5DBB36FF98293AFCC4FE72FAA3F951.taxon	description	DESCRIPTION Ascomata. 120 - 130 µm high, 420 - 500 µm in diameter, brown to black, subglobose, coriaceous, ostiolate, papillate, pseudos - tromatic tissues surrounding each ascoma. Necks erumpent. Paraphyses. 4 - 8 µm thick, filiform and simple. Asci. 200 - 248 × 20 - 37 µm, 8 - spored, irregularly fusiform, pedicellate, unitunicate, thin-walled, without an apical ring. Ascospores. 153 - 210 × 4 - 5.5 µm, filiform, tapering towards both ends, the end cells lack cytoplasmic contents and appear curved or hook-shaped at one end, 12 - 13 - septate, not constricted at the septa, with longitudinal striations running the length of the ascospore, slightly brown. NOTES Pedumispora rhizophorae is seldom reported from tropical mangrove habitats (Jones et al. 2009, 2013). It was originally collected from decayed intertidal prop roots and twigs of Rhizophora apiculata at Ranong Province, southern Thailand (Hyde & Jones 1992). Later collections were made on R. mucronata from Seychelles (Hyde & Jones 1992) and mangrove wood from Guam, (Sakayaroj et al. 2005). Hyde & Jones (1992) included Pedumispora rhizophorae in Melanconidaceae, Diaporthales, as it has similar characters to Prosthecium and Winterella. A preliminary phylogenetic study, based on LSU sequence data of the strain obtained from Guam, revealed that Pedumispora rhizophorae has an affinity with the Xylariales, and in particular with the Diatrypaceae (Sakayaroj et al. 2005; Jones et al. 2009). Klaysuban et al. (2014) re-examined the morphology of this fungus and and confirmed its taxonomic position within Diatrypaceae through a molecular phylogenetic study with LSU and ITS sequences.	en	Dayarathne, Monika C., Wanasinghe, Dhanushka N., Devadatha, B., Abeywickrama, Pranami, G, E.
