MycoBank number: MB 2467; Index Fungorum number: IF 2467; Facesoffungi number: FoF 08059; 3 morphological species (Almeida et al. 2014, Species Fungorum 2020), molecular data unavailable.
Type species – Hysteroglonium ovatum (Cooke) Lindau, in Engler & Prantl, Nat. Pflanzenfam., Teil. I (Leipzig) 1(1): 274 (1897).
≡ Hysterium ovatum Cooke, Grevillea 11(no. 59): 107 (1883).
Notes – 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 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.
