Gloeodiscus
Gloeodiscus Dennis, Kew Bull. 15(2): 319 (1961).
Index Fungorum number: IF 2080; Facesoffungi number: FoF 12219, 1 morphological species (Species Fungorum 2022), no molecular data available.
Parasitic on leaves in terrestrial habitats. Sexual morph: Ascomata solitary or scattered, semi-immersed or superficial, globose to subglobose, wall dark brown to black, coriaceous and spores release via a slit. Peridium comprising two layers, outer layer consisting of small, heavily pigmented, pseudoparenchymatous, dark brown cells, inner layer composed of wide, light brown cells of textura angularis. Hamathecium composed of cellular pseudoparaphyses, anastomosing between asci. Asci 8-spored, fissitunicate, ovoid to sub-cylindrical, with a short, broad pedicel, apically thickened and rounded with an ocular chamber. Ascospores cylindrical with narrowly rounded ends, hyaline, 4-septate, but breaking in to part spores, smooth-walled. Asexual morph: Unknown (adapted from Ariyawansa et al. 2013).
Type species: Gloeodiscus nigrorufus (Berk.) Dennis
Notes: Gloeodiscus is characterised by solitary or scattered ascomata, ovoid to sub-cylindrical or cylindrical asci with narrowly rounded ends and hyaline, 4-septate ascospores. Berkeley in Hooker (1845) referred Excipula nigrorufa (basionym of Gloeodiscus nigrorufus) to the order Helotiales. Dennis (1961) transferred Gloeodiscus to Dothideomycetes, genera incertae sedis. Lumbsch and Huhndorf (2010), Kirk et al. (2013), Wijayawardene et al. (2014, 2020) and Ariyawansa et al. (2013) also referred Gloeodiscus to Dothideomycetes, genera incertae sedis. Molecular data is lacking. Fresh collections with DNA sequence data are needed to confirm the generic placement of Gloeodiscus.
