038F87CAFF88E16E7CD8FDC81646F956.taxon	materials_examined	Type: — [GERMANY, Schleswig-Holstein] Bramsted, erratische Blöcke bei Bimöhlen, auf einer Weide, 27.05.1915, leg. Erichsen (lectotype HBG — designated here, Mycobank MB 10000452). Figure 1. The type specimen of Pertusaria inopinata is characterized by a hardly rimose, dark grey to olive-greenish, not areolated thallus, with numerous irregular, rounded, 0.2 – 0.3 mm wide, grey-whitish to olive-greenish soralia (Figure 1). According to Erichsen (1936) the thallus reacts P + yellow, K + yellow, C – and I –. Norstictic acid and traces of lecanoric and gyrophoric acids were detected by own chemical analyses. This name was reported from Denmark (Søchting & Alstrup 2002), Germany (Erichsen 1936) and Poland (Alstrup & Olech 1992). The type of Pertusaria inopinata is morphologically and chemically concordant with Lepra excludens (Nylander 1885: 296) Hafellner, in Hafellner & Türk (2016: 172) (syn. Pertusaria excludens Nyl.). Therefore P. inopinata should be considered as a synonym of L. excludens. During herbarium studies three original specimen of P. inopinata were found in HBG, one collected by Erichsen and annotated as ‘ Typus’ consists of two pieces of stone with the same thallus (Figure 1). The other two were cited in the protologue, but collected by Lettau and Schade. All samples studied correspond in morphological and anatomical characters with the description provided by Erichsen (1936). The chemistry of the type specimen annotated as ‘ typus’ and other samples were checked by P. James and norstictic acid and traces of lecanoric and gyrophoric acid were detected (Hanko 1983). The presence of these secondary metabolites is confirmed by own research. Hanko (1983) cited as a ‘ typus’ the specimen collected by Schade (“ DDR. Sachsen: Leusitzer Niederung 7.1936, Schade, HBG- 1213 ”), but the data presented by Hanko (1983: 201) do not match those given in the protologue by Erichsen (1936: 99), therefore, his typification cannot be considered effective, and consequently, a new lectotype of P. inopinata is designated (Turland et al. 2018). Syntypes of P. inopinata examined. [Germany] Thüringen: Manebach im Thüringer Wald, auf Porphyrsteinchen eines begrasten Waldweges, 750 m, leg. G. Lettau (HBG). [Sachsen] Krs.

038F87CAFF8BE16F7CD8F884108BF7A2.taxon	materials_examined	Type: — [Switzerland] SCHWEIZ, Jura, Neuenburg, Val Travers, Buttes am Sorbus einer Allé, 850 m., 03.10.1928, leg. E. Frey 1294 (lectotype HBG — designated here, Mycobank MB 10000525). Figure 2. The type is characterized by whitish thallus with semiglobose, in part sorediate, scattered or crowded warts. The thallus is zoned at the margin. Soralia with granular soredia are very frequent, whitish to greenish grey (Figure 2). The analysis of secondary metabolites (TLC) showed the presence of fatty acids. Pertusaria jurana was described from Switzerland and the name has later been reported from Europe only (Erichsen 1935 [1936]; Hocevar et al. 1995; Fałtynowicz 2003; Clerc 2004; Knežević & Mayrhofer 2009). It is chemically and morphologically concordant with the present circumscription of Lepra albescens (Hudson 1762: 445) Hafellner (in Hafellner & Türk, 2016: 171) (Chambers et al. 2009) and is thus considered synonymous here. In the protologue Erichsen cited four specimens of Pertusaria jurana, but did not determine any specimen as a holotype. Three of them are deposited in HBG. One sheet collected from Schwiez is annotated as ‘ Typus’ with handwritten notes of Erichsen and in this case it should be designated as lectotype (Turland et al. 2018). The type of Pertusaria jurana consists of two pieces of bark with the same thallus. Morphological characters of both correspond to the description in the protolouge.	en	Oset, Magdalena (2021): On the identity of some taxa of Pertusaria (lichens) described by C. F. E. Erichsen.

038F87CAFF8DE1687CD8FF02128AFC10.taxon	materials_examined	Type: — [Switzerland] SCHWEIZ, Jura, Neuenburg, an Wegulmen bei Buttes, 800 m., 03.10.1928, leg. E. Frey (367) (holotype HBG!). Figure 3. The thallus of the type specimen of Pertusaria jurana var. confluens in HBG is quite thick, whitish-grey and sorediate, with a whitish to brownish prothallus. Soralia are grey-whitish, abundant, orbicular to irregular, discrete, and separated from each other (see Sipman 2006) (Figure 3). The presence of variolaric acid has been detected by TLC. The type specimen Pertusaria jurana var. confluens is morphologically and chemically concordant with Ochrolechia turneri (Smith 1801: 857) Hasselrot (1945: 130) (Kukwa 2011). Therefore it should be treated as a synonym of the latter name (Turland et al. 2018). According to Kukwa (2011) there are two other corticolous and sorediate Ochrolechia species with variolaric acid, O. alboflavescens (Wulfen, in Jacquin 1791 [1789]: 111) Zahlbruckner (1927 [1926]: 94) and O. microstictoides Räsänen (1936: 226), which resemble O. turneri. Ochrolechia albofavescens has often well-separated soralia, like O. turneri, but it contains in addition to variolaric acid also fatty acids, lichesterinic and protolichesterinic acids. Ochrolechia microstictoides is very variable in thallus morphology, but in general its soralia are irregular and often confluent, but can be distinguished by the presence of lichesterinic acid, which is produced in addition to variolaric acid (Kukwa 2011). Another species which may produce variolaric acid is Varicellaria hemisphaerica (Flörke 1815: 6) I. Schmitt & Lumbsch in Schmitt et al. (2012: 29). The species is characterized by the pale bluish-grey tinged thallus with an often broad white margin and conspicuous, paler or concolorous, convex soralia. It can be, however, easily differentiated by the presence of lecanoric acid giving C + carmine red reaction of soralia (Tønsberg 1992; Chambers et al. 2009; Schmitt et al. 2012).	en	Oset, Magdalena (2021): On the identity of some taxa of Pertusaria (lichens) described by C.
