Classification: Lasiosphaeridaceae, Sordariales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Saprobic on wood. Sexual morph: Ascomata perithecial, solitary, superficial to semi-immersed, subglobose to obpyriform, black, ostiolate, tuberculate or/and surrounded by brown, septate setae or hairs. Asci 8-spored, unitunicate, cylindrical, with J- apical ring and a subapical globule. Ascospores cylindrical to geniculate or sigmoid, aseptate to multi-septate, ends rounded, hyaline to pale brown, becoming brown to dark brown, ellipsoidal to broadly fusiform at apical cell(s), sometimes with terminal, short, conical gelatinous appendage at each end. Asexual morph: Hyphomycetous, phialophora-like. Conidia oval to globose, hyaline (adapted from Tode 1791; Miller and Huhndorf 2004a).

Notes: Lasiosphaeris was established based on Sphaeria hispida (Clements 1909) and Réblová et al. (2011) introduced Lasiadelphia lasiosphaeriae for the asexual morph of Lasiosphaeris hispida. However, Réblová et al. (2016) recommended to use the old Lasiosphaeris over Lasiadelphia. Lasiosphaeris is characterized by hairy ascomata, cylindrical to clavate asci with apical globule and geniculate or sigmoid ascospores (Tode 1791; Hilber and Hilber 1979), which is related to Immersiella and Lasiosphaeria in morphology, but distinct in phylogenetic analysis. Lasiosphaeris species clustered as an independent clade in Sordariales based on single/multi-gene analysis (Miller and Huhndorf 2004a; Kruys et al. 2014; Marin-Felix et al. 2020). This resulted in Lasiosphaeris being placed in Sordariales genera incertae sedis (Miller and Huhndorf 2004a; Wijayawardene et al. 2020). Since a large number of lasiosphaeriaceous taxa have been repositioned according to the phylogenetic analysis (Marin-Felix et al. 2020), we raised Lasiosphaeris as a novel family, Lasiosphaeridaceae, which includes all Lasiosphaeris species and is branched out of other families in Sordariales (72%ML) in our phylogenetic analysis.

Type species: Lasiosphaeris hispida (Tode) Clem., Gen. fung. (Minneapolis): [173] (1909).

Other accepted species: Species Fungorum – search Lasiosphaeris.
