Murispora galii Wanasinghe, N. Camporesi, E.B.G. Jones & K.D. Hyde, in Wanasinghe, Jones, Camporesi, Wijayawardene, Mortimer, Xu, Bahkali & Hyde, Cryptog. Mycol. 36(4): 437 (2015)
Facesoffungi Number: FoF 01105; Index Fungorum number: IF551557
Etymology: Name reflects the host genus Galium, from which the species was collected.
Holotype: MFLU 15-2247
Saprobic on dead herbaceous branches in terrestrial habitats. Sexual morph: Ascomata 250-350 μm high 250-310 μm diam. (x̅ = 275.4 × 271.7 μm, n = 10), globose to subglobose, solitary, dark brown to black, erumpent to nearly superficial, substrate stained purple, ostiolate. Ostiole 80-130 μm high 60-90 μm diam. (x̅=123.2 × 73.4 μm, n = 5), short to papillate, black, smooth, ostiolar canal filled with hyphae. Peridium 12-18 μm wide at the base, 15-25 μm wide on sides, composed of brown to dark brown or reddish brown, pseudoparenchymatous cells of textura angularis. Hamathecium comprising numerous, 1.5-2.5 μm (n = 30) wide, filamentous, branched, septate, pseudoparaphyses. Asci 150-200 × 20-30 μm (x̅ = 172.1 × 23.7 μm, n = 40), 8-spored, bitunicate, fissitunicate, cylindric-clavate, short pedicellate, thick-walled at the apex, with a minute ocular chamber. Ascospores 35-40 × 10-15 μm (x̅ = 37.5 × 13.2 μm, n = 50), overlapping 1-2-seriate, hyaline when young, becoming brown at maturity, curved-fusoid, asymmetrical with one side flattened, muriform, with 2-3 longitudinal septa in all cells, slightly constricted at the middle septum, widest above the central septum, conical and narrowly rounded at the ends, initially guttulate, with a rugged surface, surrounded by a mucilaginous sheath. Asexual morph: Undetermined.
