NotesHysteroglonium 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 pseudo- triseptate. 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.
