Epicoleosporium

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 2022), 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, subcylindrical, 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 is characterised by immersed mycelium, subcylindrical conidiophores, and conidia that are solitary or in short chains. 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). Molecular markers available for Epicoleosporium are ITS, LSU, chs, RPB2 and TEF-1.
