Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1

Classification: Incertae sedis, Sordariales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Coprophilous Sexual morph: Ascomata cleistothecial, scattered, superficial, globose to subglobose, semi-translucent to opaque, dark brown to black, surrounded by brown, septate hairs. Peridium membranaceous, composed of brown cells of textura angularis to textura prismatica. Asci 8-spored, unitunicate, clavate to cylindrical, pedicellate, evanescent, apex rounded or truncate, with J- apical ring. Paraphyses filiform or absent. Ascospores bi-seriate or irregularly arranged, cylindrical, aseptate and hyaline when young, upper cell(s) becoming swollen and fusiform, 0–1-septate, brown to olivaceous brown, guttulate, with truncate base and an apical germ pore, collapsing when dry; lower cell(s) tail-like, hyaline, aseptate to multi-septate, smooth-walled, slightly curved near the base. Asexual morph: Undetermined (adapted from Subramanian and Lodha 1968; Abdullah and Rattan 1978).

Notes: Tripterosporella was isolated from herbivores dung (horses and cows), and is similar to lasiosphaeriaceous taxa in having ascospores with brown upper cell(s) and a long hyaline pedicel (Subramanian and Lodha 1968; Doveri 2010; Wijayawardene et al. 2020). We place Tripterosporella in Sordariales genera incertae sedis but phylogenetic data is required to confirm its placement.

Type species: Tripterosporella coprophila Subram. & Lodha, Curr. Sci. 37: 246 (1968).

Other accepted species: Species Fungorum – search Tripterosporella.
