Hysteroglonium contains saprobes, terrestrial and cosmopolitan species (Lumbsch & Huhndorf 2010). Only hysteriaceous ascomata are recorded and asexual morph is undetermined (Lumbsch & Huhndorf 2010, Doilom et al. 2018). Cooke (1883) and Engler & Prantl (1896) described the type of this genus H. ovatum as follows: Ascomata hysterothecia, superficial, longitudinal to host surface, straight, flat or convex on top, black, solitary, scattered, slightly shiny, semi-immersed, becoming superficial. Asci 8-spored, bitunicate, subcylindrical, apically rounded. Ascospores ellipsoid, rounded at both sides, hyaline, guttulate, aseptate, finally becoming pseudotriseptate. Cultures and sequences data are unavailable for this genus and fresh specimens and isotypes need to be designated. Molecular data is needed to confirm placement of this genus.
