Chuppomyces Videira & Crous, in Videira, Groenewald, Nakashima, Braun, Barreto, de Wit & Crous, Stud. Mycol. 87: 370 (2017).
Index Fungorum number: IF 822582; Facesoffungi number: FoF 08486, 1 morphological species (Species Fungorum 2021), 1 species with molecular data.
Saprobic on host. Sexual morph: Unknown. Asexual morph: Mycelium composed of hyaline to pale olivaceous brown hyphae, smooth to rough. Conidiophores macronematous, pale olivaceous brown, rough, straight or strongly geniculate, simple. Conidiogenous cells integrated, terminal or intercalary, thickened and darkened, proliferating sympodially, polyblastic, apex short-conically truncate, with rim-like conidiogenous loci, thickened and darkened, located on the apex and shoulders. Conidia solitary, hyaline, smooth, cylindrical to obclavate, septate (Adapted from Videira et al. 2017).
Type species: Chuppomyces handelii (Bubák) U. Braun, C. Nakash., Videira & Crous
Notes: Chuppomyces was introduced by Videira et al. (2017) with C. handelii as type species. Chuppomyces is characterized by macronematous conidiophores, terminal or intercalary conidiogenous cells, solitary, hyaline conidia. In the phylogenetic analysis of Videira et al. (2017), Chuppomyces is closely related to Ruptoseptoria. Chuppomyces differs from Ruptoseptoria in that the latter has convoluted conidiomata that open by irregular rupture and often form phialidic conidiogenous cells while Chuppomyces has sympodially proliferating conidiophores and conidia which are hyaline, solitary, cylindrical and multiseptate. Chuppomyces is a distinct and well-supported lineage in Mycosphaerellaceae.
