Halbania
Halbania Racib., Crypt. Par. Java: no. 89 (1889).
Index Fungorum number: IF 2201; Facesoffungi number: FoF 06735, 3 morphological species (Species Fungorum 2022), no molecular data available.
Epiphytes forming black spots. Superficial hyphae at the margin of thyriothecia brown, irregular, appressoria not observed. Sexual morph: Thyriothecia superficial, scattered, rounded to oval, flattened, brown to black, opening by stellate fissures. Upper wall comprising an irregular arrangement of dark cells, cells at margin branching and forming superficial hyphae, basal peridium poorly developed. Hamathecium lacking pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate dehiscence not observed, thick-walled, saccate to obovoid, sometimes globose, lacking or with a short pedicel, apical region of asci usually with a thick opaque region, ocular chamber not apparent, arranged vertically in thyriothecia. Ascospores 2–3-seriate, fusiform, brown, 3-septate. Asexual morph: Unknown (adapted from Hongsanan et al. 2014).
Type species: Halbania cyathearum Racib.
Notes: Halbania comprises three poorly known species. Halbania resembles Batistinula in having 3-septate ascospores, but lacks appressoria on the hyphae. Molecular data is lacking. Fresh specimen with DNA sequence data are needed to confirm the taxonomic placement of Halbania.
