Classification: Bombardiaceae, Sordariales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Coprophilous. Sexual morph: Ascomata perithecial, solitary to scattered, immersed to semi-immersed, pyriform to subglobose, brown to black, ostiolate. Peridium comprising membranaceous to coriaceous, pale brown to brown cells. Paraphyses numerous, filiform, evanescent. Asci 4–8-spored, unitunicate, cylindrical, pedicellate, apex rounded. Ascospores uni-seriate, ellipsoidal to oval, aseptate, hyaline to brown to dark brown, with a germ pore at one or each end, surrounded by hyaline, gelatinous sheath. Asexual morph: Hyphomycetous. Phialides abundant, hyaline, reduced to collarettes producing conidia. Conidia ovoid, hyaline, aseptate (adapted from Lundqvist 1964b; Kruys et al. 2014).
Notes: Lundqvist (1964b) transferred Sordaria rabenhrstii to Fimetariella as its type species. It is characterized by pyriform ascomata and aseptate ascospores surrounded by a hyaline, gelatinous sheath. Kruys et al. (2014) sequenced F. rabenhorstii (20410), which was isolated from moose dung in Sweden and collected by Lundqvist. This strain is basal to Podospora fabiformis and P. fibrinocaudata in Bombardiaceae (100%ML/1.00PP).
Type species: Fimetariella rabenhorstii (Niessl) N. Lundq., Bot. Notiser 117: 239 (1964).
Other accepted species: Species Fungorum – search Fimetariella.
