Camarosporomyces Crous, in Crous & Groenewald, IMA Fungus 8(1): 141 (2017).
Index Fungorum number: IF 820901; Facesoffungi number: FoF 08168, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Pathogenic on plant substrate and water. Sexual morph: Unknown. Asexual morph: Conidiomata pycnidial, solitary to aggregated, obovoid, medium brown, with prominent papillate ostiole, dark brown, with extra 1–2 layers of wall at the apex (thicker than pycnidial body), periphysate. Conidiophores reduced to conidiogenous cells lining inner cavity, hyaline, smooth, ampulliform; phialidic with periclinal thickening. Conidia solitary, hyaline, smooth, aseptate, subcylindrical, straight, apex obtuse, base truncate (adapted from Crous et al. 2017).
Type species: Camarosporomyces flavigenus (Constant. & Aa) Crous
Notes: Camarosporomyces resembles Phoma in having solitary, hyaline conidia but differs from phoma-like genera in having pycnidial conidiomata with prominent papillate dark brown periphysate ostiole, and thicker wall at apex. Phylogenetically, Camarosporomyces is a well-supported genus in Camarosporiaceae. Molecular markers available for Camarosporomyces are ITS, LSU and SSU.
