Classification: Incertae sedis, Sordariales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Saprobic on wood or lichens. Sexual morph: Ascomata perithecial, solitary, superficial to semi-immersed, membranaceous, pyriform to subglobose, black, verrucose, ostiolate, with papilla. Peridium composed of pale brown to hyaline cells of textura angularis to textura prismatica. Paraphyses evanescent. Asci 8-spored, unitunicate, cylindrical to ellipsoidal, pedicellate, apex rounded. Ascospores uni-seriate, ellipsoidal to fusiform, aseptate, pale brown to dark brown, smooth-walled, with guttules. Asexual morph: Undetermined (adapted from Matzer and Hafellner 1990; Matzer 1993; Alstrup et al. 1994; Kondratyuk et al. 2013).
Notes: Roselliniopsis was established as a lichenicolous genus in Sordariales and is typified by R. groedensis (Matzer and Hafellner 1990; Maharachchikumbura et al. 2016; Hyde et al. 2020; Wijayawardene et al. 2020). It is placed in Sordariales genera incertae sedis and characterized by superficial ascomata with brown setae and pale brown ascospores (Matzer and Hafellner 1990), but no molecular data is available.
Type species: Roselliniopsis groedensis (Zopf) Matzer & Hafellner, Biblthca Lichenol. 37: 99 (1990).
Other accepted species: Species Fungorum – search Roselliniopsis.
