Type species – Longispora clematidis Phukhams. & K.D. Hyde, Fungal Diversity 102: 81 (2020).
Notes – A monotypic genus Longispora was introduced by Phukhamsakda et al. (2020) to accommodate ophiobolus-like taxon. The generic type, Longispora clematidis also shares morphological characters with Leptospora in producing red pigments in the ostiole. Longispora was collected from dead aerial branch of Clematis vitalba in Italy and is unique in having erumpent to superficial, globose to subglobose ascomata, cupulate when dry, with minute papilla and reddish ostiole, cylindric-clavate asci with bulbose pedicellate embedded in cellular pseudoparaphyses and pale yellowish to yellowish, filiform, multi-septate ascospores, with an enlarge cell at the middle, but not separating into single celled spores. Multi-gene phylogenetic analyses showed that the genus formed a basal lineage with Leptospora and Populocrescentia in Phaeosphaeriaceae (Phukhamsakda et al. 2020).
