Type species – Aquastroma magniostiolata Kaz. Tanaka & K. Hiray. Stud. Mycol. (2015).
Notes – Aquastroma magniostiolata was found in Japan on submerged twigs of a woody plant. This genus shares a close affiliation to Quintaria in having multi-septate ascospores and aquatic habitat. However, they are phylogenetically not closely related. See Tanaka et al. (2015) for further details.
