Eriomycopsis Speg., Anal. Mus. nac. B. Aires, Ser. 3 13: 429 (1910) .
Index Fungorum number: IF 8203; Facesoffungi number: FoF 12207, 13 morphological species (Species Fungorum 2022), no molecular data available.
Hyperparasitic on ascocarps of host. Sexual morph: Unknown. Asexual morph: Colonies effuse, whitish. Mycelium internal as well as external. External hyphae creeping overgrowing the peridium and climbing setae, solitary thread, loose webs to dense aggregations of appressed to interwoven hyphae and swollen hyphal cells. Hyphae hyaline, smooth septate, branched. Conidiophores solitary to loosely caespitose, arising from superficial hyphae, lateral or terminal or from aggregated swollen hyphal cells, erect, straight, subcylindric to sinuous, non-geniculate, usually attenuated from base to top, apex denticulate, denticles subcylindric, 0–2septate, hyaline, smooth. Conidia solitary, fusiform, obclavate (-subclavate), straight to falcate, (1–)
Type species: Eriomycopsis bomplandi Speg.
Notes: Eriomycopsis is characterised by erect, simple, continuous or septate conidiophores, and acro-pleurogeneous fusoid or filiform, 1-multi-septate, hyaline ascospores. Sydow (1929) added a second species E. tenuis, parasitic on Parodiopsis stevensii (Parodiopsidaceae). The holotype specimen of E. bomplandi is lost. Molecular data is lacking for Eriomycopsis. Fresh collections with DNA sequence data are needed to confirm the generic placement of Eriomycopsis.
