Briansuttonomyces Crous, in Crous & Groenewald, Fungal Biology 120(11): 1412 (2016).

 Index Fungorum number: 816146; Facesoffungi number: FoF 08218, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.

Saprobic on leaf. Sexual morph: Unknown. Asexual morph: Conidiomata coelomycetous, pycnidial, 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 is characterised by brown eustromatic conidiomata, ampulliform to globose conidiogenous cells, solitary hyaline (0–)1-septate conidia. Briansuttonomyces resembles Coleophoma, but differs in that the conidia areuniseptate, and the conidiomata lack paraphyses. Phylogenetically, Briansuttonomyces is a well-supported monophyletic lineage in Didymellaceae. Molecular markers available for Briansuttonomyces are ITS, LSU, BTUB and RPB2.
