Saprobic on dried wood substrate. Sexual morph: Ascomata immersed to semi-immersed, uniloculate, globose to subglobose, Ostiole long, central locate. Peridium thick, comprising several layers with scleroplectenchymatous or pseudoparenchymatous cell types, black to dark brown cells. Hamathecium comprising numerous, cellular pseudoparaphyses. Asci 4–8-spored, bitunicate, fissitunicate, cylindrical to clavate. Ascospores mostly overlapping 1-seriate or 2–3-seriate, broad fusiform, hyaline, brownish at the senescent state, multi-septate. Asexual morph: Pycnidia conidiomata or hyphomycetous-like structures produced in the cultures condition. (Li et al. 2016a, Matsumura et al. 2018).

Notes: Crassiperidium and Longiostiolum were introduced by Matsumura et al. (2018) and Li et al. (2016a), respectively. The genera were treated as Pleosporales genera incertae sedis. Phukhamsakda et al. (2020), indicated that Crassiperidium clustered with Longiostiolum based on multi-gene phylogenetic analysis. Therefore, they introduce Longiostiolaceae to accommodate the distinct lineage in Pleosporales. Later, Wanasinghe et al. (2020b) designated a neotype for Shearia formosa and based on DNA sequence data, confirmed the family placement of Shearia as Longiostiolaceae. Currently, three genera are accepted in this family which are Crassiperidium, Longiostiolum and Shearia. 

Type genus: Longiostiolum Doilom, Ariyaw. & K.D. Hyde.
