Astrosphaeriella thailandensis J. Ren, C.Y. Jie, Y.L. Jiang, K.D. Hyde & Yong Wang bis
MycoBank no.: MB 801309
Etymology: The epitheton thailandensis refers to the country, where the holotype specimen was collected.
Sexual morph: Ascomata 600–850 μm in diam., 350–550 μm high, black, scattered, rarely clustered, superficial on host tissue, as subglobose, carbonaceous domes, base applanate, apex non-papillate. Peridium 40–60 μm thick, carbonaceous, uneven in thickness, composed of thick-walled cells. Pseudoparaphyses 0.5–1.2 μm wide, trabeculate, filiform, hyaline, persistent, numerous, septate, anastomosing and branched, embedded in a gelatinous matrix. Asci 78–144 × 5–7 μm (M = 100 × 6 μm, n = 20), 8–spored, bitunicate, fissitunicate, cylindric-clavate, with a long, thin pedicel, apex wide and rounded. Ascospores 22–25 × 3–4.5 μm (M = 23 × 3.5 μm, n = 20), fusiform, hyaline, smooth-walled, containing refractive globules, 1-septate, upper cell slightly shorter and wider, deeply constricted at the middle septum. Asexual morph: Undetermined. (Description from Ren et al. 2013)
