Leptospora was introduced by Rabenhorst (1857) with L. rubella as the type species. Leptospora species have large, flask-shaped ascomata with long cylindrical asci and thin, filiform, multi-septate ascospores, and members of this genus also had been reported to produce a reddish-purple pigmentation to stain the host tissue around the ostiole (Walker 1980; Hyde et al. 2016; Zhang et al. 2019a). There are 40 species listed in Index Fungorum (2021), 15 species are listed in Species Fungorum (2021). 

Type species: Leptospora porphyrogona (Tode) Rabenh., Hedwigia 1(18): 116 (1857).

Other accepted species: Species Fungorum – search Leptospora.
