Hysterobrevium was introduced by Boehm et al. (2009) with three new combinations (Hysterobrevium constrictum, H. mori and H. smilacis) and H. mori as the type species. There are seven records in Index Fungorum (2021) with molecular data. This genus is characterized by hyaline or pigmented dictyospores, usually less than 25 μm long, and constricted at least at the median septum (Boehm et al. 2009).
Type species: Hysterobrevium mori (Schwein.) E. Boehm & C.L. Schoch, in Boehm, Mugambi, Miller, Huhndorf, Marincowitz, Spatafora & Schoch, Stud. Mycol. 64: 62 (2009)
Other accepted species: Species Fungorum – search Hysterobrevium.
