Perthomyces
Perthomyces Crous, in Crous et al., Persoonia 38: 257 (2017)
Index Fungorum number: IF 820934; Facesoffungi number: FoF 08235, 1 morphological species (Species Fungorum 2021), 1 species with molecular data.
Saprobic on leaves. Sexual morph: Unknown. Asexual morph: Conidiomata solitary, erumpent, globose, dark brown with central ostiole, exuding a white conidial mass; wall of 3–8 layers of brown textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells lining the inner cavity, hyaline, smooth, ampulliform to doliiform or subcylindrical, phialidic with periclinal thickening or tightly aggregated, percurrent proliferations. Conidia solitary, hyaline, smooth, guttulate, aseptate, subcylindrical with obtuse ends, straight (adapted from Crous et al. 2017).
Type species: Perthomyces podocarpi Crous
Notes: Perthomyces is characterised by dark brown solitary conidiomata, hyaline, smooth, ampulliform to doliiform conidiogenous cells and hyaline aseptate conidia. The taxonomic placement of Perthomyces is uncertain and is currently in Pleosporales genera incertae sedis. More collections are required to determine the correct position of Perthomyces. Molecular markers available for Perthomyces are ITS, LSU and BTUB.
