Briansuttonomyces Crous, Fungal Biol. 120(11): 1412 (2016)

Index Fungorum number: IF 816146; Facesoffungi number: FoF 08218, 1 morphological species (Species Fungorum 2021), 1 species with molecular data.

Saprobic on leaf. Sexual morph: Unknown. Asexual morph: Conidiomata erumpent, eustromatic, brown, globose, with central ostiole; wall of 3–8 layers of medium brown textura angularis. Conidiogenous cells lining inner cavity, hyaline, smooth, thin walled, ampulliform to globose, phialidic with periclinal thickening and minute collarette. Conidia solitary, hyaline, smooth, guttulate to granular, cylindrical with obtuse ends, (0–)1- septate, mostly straight (Adapted from Crous and Groenewald 2015).


Type species: Briansuttonomyces eucalypti Crous


Notes: Briansuttonomyces was introduced by Crous with B. eucalypti as type species. Briansuttonomyces is characterized by brown eustromatic conidiomata, ampulliform to globose conidiogeneous cells, solitary hyaline (0–)1- septate conidia. Briansuttonomyces resembles Coleophoma, but differs in that the conidia are 1-septate, and the conidiomata lack paraphyses. Phylogenetically, Briansuttonomyces is a well-supported monophyletic lineage in Didymellaceae.
