Type species – Pisorisporium cymbiforme Réblová & J. Fourn.
Notes – The genus was introduced by Réblová et al. (2015a), to accommodate taxa isolated from decaying wood submerged in freshwater and is characterized by brown to black astromatic ascomata and a J+, apical ring in the asci. The ascospores of Pisorisporium cymbiforme are slightly constricted at the septa, while the paraphyses and ascospores have thick walls.
