0382879926099776FE9513E1FC0F8CF2.taxon	diagnosis	DIAGNOSIS. — Basidiomata annual, resupinate, effused, closely adnate, gelatinous to crustaceous. Margin adnate, fimbriate. Hymenial surface covered by sharp-pointed sterile spines (hyphal pegs) formed by a thin core made of hyphae (hyphal core) enclosed by abundant crystals. Hyphal structure monomitic, hyphae clamped. Cystidia fusiform, cylindrical, often sinuous, some with refractive content. Hyphidia in hymenium, hyaline, thin-walled. Fertile hyphae, tortuous, forming 2 - 4 basidia at the apex, collapsed basidia often present. Basidia ellipsoid-ovoid, 4 - celled, basidiospores cylindrical to broadly cylindrical, slightly curved, with oil droplets in the cytoplasm. Phylogenetically, the genus represents a new lineage in Auriculariales.	en	M, Renato Lúcio, Alvarenga, endes, Gibertoni, Tatiana Baptista (2021): Crystallodon Alvarenga gen. nov., a new genus of the Auriculariales from the Neotropics.

0382879926099776FE9513E1FC0F8CF2.taxon	discussion	NOTES Recently, Brazilian specimens displaying hyphal pegs were proposed to be attributed to two new genera, Adustochaete and Metulochaete (Alvarenga et al. 2019; Spirin et al. 2019 b). In Adustochaete, hyphal pegs are formed by smooth tramal hyphae and encrusted dendrohyphidia, while in Metulochaete hyphal pegs are formed by densely glued hyphae with strongly encrusted apical parts similar to metuloid cystidia. Therefore, so far, Crystallodon Alvarenga gen. nov. is the only genus among resupinate Auriculariales that has been reported to display hyphal pegs formed by a thin core of hyphae covered by angular crystals.	en	M, Renato Lúcio, Alvarenga, endes, Gibertoni, Tatiana Baptista (2021): Crystallodon Alvarenga gen. nov., a new genus of the Auriculariales from the Neotropics.

VI. 2018, Gibertoni, TB (TBG 4 b, TBG BF- 18001 – URM 93445); Chikowski, R. S. (RC 1609 – URM 93444); Tamandaré, Reserva Biológica de Saltinho, 25. VI. 2018, Xavier-Lima, V (VXLF 166 – URM 93443). DESCRIPTION Basidiomata Annual, resupinate, effused, closely adnate, later fusing with adjoining basidiomata, gelatinous when fresh, crustaceous when dried. Margin adnate, fimbriate, paler than hymenial surface (5 C 4). Hymenial surface gelatinized when fresh, light brown (5 D 5), densely covered by sharp-pointed sterile spines formed by hyphae enveloped by often apically branched crystals, spines 75 - 355 × 35 - 40 µm [50 - 80 µm, notes by Viacheslav Spirin about the type specimen (pers. com.)], 5 - 6 per mm. Hyphal structure monomitic, hyphae clamped. Subiculum Not clearly differentiable, subhymenium with hyphae hyaline, thin-walled, 1 - 2.5 µm, clamped. Cystidia Fusiform, cylindrical to often sinuous, 45 - 50 × 4 - 7 µm, some with refractive content. Hyphidia Abundant in hymenium, hyaline, thin-walled, 0.5 - 1 µm at apex. Fertile hyphae 1 - 3 µm, tortuous, forming 2 - 4 basidia at the apex. Basidia Ellipsoid-ovoid, 4 - celled, 10.7 - 18.6 × 4.8 - 8.2 µm [15 - 20 × 10 - 12 µm in the original description by Bodman (1952); (14.2 -) 15 - 19.8 (- 22) × (8 -) 8.5 - 14.2 (- 16) µm by V. Spirin (pers. com.)]. Basidiospores Cylindrical to broadly cylindrical, slightly curved, (8 -) 8.0 - 11.7 (- 12) × (3.7 -) 4 - 6.1 (- 6.6) µm (n = 24 / 1), L = 10.4, W = 5.21, Q’ = (2.4 -) 1.64 - 2.65, Q = 2.26, with oil droplets in the cytoplasm [(9 -) 10 - 13 (- 15) × (4.5 -) 5 - 6 (- 7.5) µm in the original description by Bodman (1952); 10 - 13.9 × 5 - 6 µm by V. Spirin (pers. com.)]. NOTES Crystallodon subgelatinosum comb. nov. can be easily recognized by the hyphal pegs, formed by few subicular hyphae densely covered with angular crystals, and by the dark brown hymenophore. The presence of hyphal pegs covered by crystals may occur in different genera of Auriculariales (e. g. Adustochaete, Eichleriella) (Malysheva & Spirin 2017; Alvarenga et al. 2019); however, such hyphal pegs are commonly formed by thickwalled hyphae from the subiculum, and thus are different from those of Crystallodon Alvarenga gen. nov. Crystallodon subgelatinosum comb. nov. was first described by Bodman (1952) as Heterochaete subgelatinosa, based on specimens from Panama, this being the only record of the species until now. Basidia and basidiospores from the Brazilian collections are slightly smaller than those from the original description (Bodman 1952) and the notes provided by V. Spirin (pers. com.), and spines are narrower than those observed by V. Spirin (pers. com.); therefore, these collections may represent a different species. However, we prefer to consider these differences as due to intraspecific variation until additional material has been collected from the type locality, and morphologically and genetically analyses for a better distinction and delimitation of the taxon.	en	M, Renato Lúcio, Alvarenga, endes, Gibertoni, Tatiana Baptista (2021): Crystallodon Alvarenga gen. nov., a new genus of the Auriculariales from the Neotropics.
