Matsushimamyces
Matsushimamyces Rah. Sharma & Roh. Sharma, in Sharma et al., IMA Fungus 6(2): 338 (2015).
Index Fungorum number: IF 810895; Facesoffungi number: FoF 07744, 2 morphological species (Species Fungorum 2022), 2 species with molecular data.
Pathogenic on horse hair. Sexual morph: Unknown. Asexual morph: Conidiophores solitary, erect, rarely branched, straight or flexuous, brown apically, smooth, beaded near conidium attachment points, constricted at the septa. Conidiogenous cells pale brown, coarsely verruculose, monoblastic, terminal. Conidia solitary, straight or curved, fusoid to broadly ellipsoid, phragmo-septate, apical and basal cell thin-walled, subhyaline to brown, median cells dark brown to black, thick-walled, roughly to coarsely verruculose (adapted from Sharma et al. 2015).
Type species: Matsushimamyces bohaniensis Rah. Sharma, Roh. Sharma & Crous
Notes: Matsushimamyces resembles species of the genus Bahugada but is distinct in that the latter has dictyospores formed on micronematous conidiophores, with a prominently pale brown basal cell. Matsushimamyces is also similar to Septosporiopsis in having dictyo/phragmospores but the conidia of Septosporiopsis have an equatorial appendage and the conidiogenous cells proliferate per currently. Matsushimamyces also resembles Chlamydotubeufia in having fusoid to broadly ellipsoid conidia but differs in that the conidia lack vertical septa. Matsushimamyces also shares morphological similarities with Manoharachariella, Pithomyces and Hadrosporium but these are phylogenetically distinct (Castañeda-Ruiz et al. 2000). Molecular markers available for Matsushimamyces are ITS and LSU.
