Eriocercosporella R. Kumar, A.N. Rai & Kamal ex U. Braun, Monogr. Cercosporella, Ramularia Allied Genera (Phytopath. Hyphom.) 2: 398 (1998).
Index Fungorum number: IF 13082; Facesoffungi number: FoF 08606, 2 morphological species (Species Fungorum 2022), no molecular data available.
Foliicolous hyphomycetes, associated with leaf spots. Mycelium internal and external, superficial hyphae emerging through stomata, branched, pigmented, septate, thin-walled, smooth. Stromata lacking. Sexual morph: Unknown. Asexual morph: Conidiophores macronematous, mononematous, in vivo solitary, arising from superficial hyphae, lateral, simple, occasionally branched, pigmented, septate, thick-walled, smooth. Conidiogenous cells integrated, terminal, uni- to multilocal, sympodially or occasionally per currently proliferating, loci truncate, flat, broad, neither thickened nor darkened, conidiogenesis thalloblastic, i.e. at first blastic, then thallic (base of conidia ± agreeing in width with the diameter of the broad conidiogenous loci). Conidia solitary, cylindrical to subclavate, occasionally disarticulating, plurieuseptate, occasionally with 1–2 additional distosepta, thick-walled, brown, smooth, not attenuated at the base, hila truncate, broad, width ± agreeing with the diameter of the conidiogenous loci, neither thickened nor darkened, conidial secession schizolytic (adapted from Videira et al. 2017).
Type species: Eriocercosporella indica R. Kumar, A.N. Rai & Kamal ex U. Braun
Notes: Eriocercosporella is characterised by internal and external mycelium, macronematous, mononematous conidiophores, sympodially or occasionally percurrently proliferating conidiogenous cells and cylindrical to subclavate, occasionally disarticulating conidia. Eriocercosporella morphologically resembles Pseudocercospora or Sporidesmium. The placement of Eriocercosporella in Mycosphaerellaceae is doubtful. Fresh collections with DNA sequence data are needed to confirm the correct taxonomic position of the genus.
