Cumuliphoma Valenz.-Lopez, Stchigel, Crous, Guarro & Cano, in Valenzuela-Lopez, Cano-Lira, Guarro, Sutton, Wiederhold, Crous & Stchigel, Stud. Mycol. 90: 38 (2017)
Index Fungorum number: IF 819878; Facesoffungi number: FoF 08220, 3 morphological species (Species Fungorum 2021), 3 species with molecular data.
Pathogenic or saprobic on hosts. Sexual morph: unknown. Asexual morph: Conidiomata pycnidial, brown, mostly confluent, pycnidial wall of textura angularis, mostly glabrous, globose or nearly so, with a single ostiole. Conidiogenous cells phialidic, hyaline, smooth walled, globose to ampulliform. Conidia aseptate, hyaline, smooth- and thin-walled, ellipsoidal to cylindrical, guttulate. Chlamydospores mostly absent (Adapted from Valenzuela-Lopez et al. 2018).
Type species: Cumuliphoma omnivirens (Aveskamp, Verkley & Gruyter) Valenz.-Lopez, Stchigel, Crous, Guarro & J.F. Cano
Notes: Cumuliphoma was introduced by Valenzuela-Lopez et al. (2018) with C. omnivirens as type species. Cumuliphoma is characterized by aseptate conidia which are hyaline, smooth- and thin-walled, ellipsoidal to cylindrical, guttulate. Cumuliphoma resembles Phoma and phoma-like genera but can be differentiated based on DNA sequence data.
