Bryomyces Döbbeler, Mitt. bot. StSamml., Münch. 14: 233 (1978).
Index Fungorum number: IF 664; Faceoffungi number: FoF 07904, 9 morphological species (Species Fungorum, 2022), molecular data unavailable.
Parasitic associated on dead parts of living hairy leaves of Scapania undulata (L.) Dumort. Sexual morph: Ascomata superficial, slightly subiculate, solitary or in groups, subglobose to globose, dark brown to black, with apical ostiole, lacking pseudoparaphyses. Peridium multi-layered, comprising compressed cells of textura angularis, hyaline to brownish at inner layers, dark brown at outer layers. Asci bitunicate, 8-spored, saccate, ellipsoid to broadly cylindrical, subclavate, apically rounded, thick-walled, ocular chamber, short pedicellate. Ascospores 2–3-seriate and overlapping, conglobate, broadly ellipsoid to subobovoid, 1-septate, septum median to supramedian, somewhat constricted at septum, upper cell wider, rounded ends, surface slightly verruculose, hyaline to lightly brown, rough-walled. Asexual morph: Undetermined (Adapted from Hyde et al., 2017).
Type species: Bryomyces scapaniae Döbbeler
Notes: Bryomyces was introduced by Dobbeler (1978) to accommodate nine species and three varieties associated with liverwort hosts. Bryomyces was placed in Pseudoperisporiaceae based on its biotrophic lifestyle and superficial dark pigmented ascomata (Barr 1997) which was followed by Hyde et al. (2013, 2017). Bryomyces is a distinct genus in Pseudoperisporiaceae but it lacks sequence data. Fresh specimen with DNA sequence data are needed to confirm the systematic position of Bryomyces.
