Epicoleosporium Videira & Crous, in Videira, Groenewald, Braun, Shin & Crous, Stud. Mycol. 83: 100 (2016).
Index Fungorum number: IF 816817; Facesoffungi number: FoF 08498, 1 morphological species (Species Fungorum 2021), 1 species with molecular data.
Saprobic on host. Sexual morph: Unknown. Asexual morph: Colonies growing on uredinia of Coleosporium, mycophylic. Mycelium superficial, consisting of hyaline, septate, thin-walled, smooth hyphae. Conidiophores hyaline, loose, straight, sub cylindrical, unbranched, septate, thin-walled, smooth. Conidiogenous cells hyaline, terminal in the conidiophore, cylindrical oblong, proliferation sympodial, with conspicuous conidiogenous loci, thickened, darkened and refractive. Conidia hyaline, smooth, solitary or in short chains, cylindrical-oblong, clavate, obovate, aseptate, thin-walled, smooth, with hila thickened, darkened and refractive (Adapted from Videira et al. 2016).
Type species: Epicoleosporium ramularioides Videira, H.D. Shin & Crous
Notes: Epicoleosporium was introduced by Videira et al. (2016) with E. ramularioides as type species. Epicoleosporium is characterized by immersed mycelium, sub cylindrical conidiophores, solitary or in short chains conidia. Epicoleosporium comprises a mycophylic species that is ramularia-like in its morphology but is not congeneric with Ramularia based on R. pusilla. Epicoleosporium is a highly supported genus in the phylogenetic analysis of Videira et al. (2016).
