Bryosphaeria
Bryosphaeria Döbbeler, Mitt. bot. StSamml., Münch. 14: 151 (1978).
Index Fungorum number: IF 671; Facesoffungi number: FoF 08381, 9 morphological species (Species Fungorum 2022), no molecular data available.
On leaves of Barbula rigidula, Lescuraea sp., Pseudoleskeella catenulata, Schistidium apocarpum, Tortula muralis. Sexual morph: Ascomata black, solitary, superficial, globose or subglobose, unilocular, setose, ostiolate. Ostiole centrally located. Setae brown, become paler and obtuse toward apex, cylindrical. Peridium composed of thick-walled, hyaline to brown cells of textura angularis. Hamathecium comprising numerous hyaline, anastomosing, branched, septate, cellular pseudoparaphyses embedded in a gelatinous matrix. Asci 8-spored, bitunicate, fissitunicate, cylindrical to fusiform or cylindric-clavate, rounded above, narrowed below, with short pedicel. Ascospores hyaline when young, then yellowish to dark brown at maturity, 2–3-seriate or multi-seriate, fusiform with broadly to narrowly rounded ends wide in the middle, 1–5-septate, constricted at septa, guttulate, verruculose. Asexual morph: Unknown (adapted from Li et al. 2014).
Type species: Bryosphaeria cinclidoti (Racov.) Döbbeler
Notes: Bryosphaeria was introduced to accommodate Leptosphaeria cinclidoti (= Bryosphaeria cinclidoti) which was previously placed in Leptosphaeriaceae. Bryosphaeria accommodate species characterised by globose or subglobose ascomata covered by brown, branched setae, bitunicate asci and hyaline to dark brown, fusiform, 1–5-septate ascospores (Döbbeler 1978, Li et al. 2014). Li et al. (2014) placed Bryosphaeria in Trematosphaeriaceae but sequence data is needed to confirm this placement.
