Crassochaeta fusispora  

Stroma absent. Ascomata 200-300 µm diam, ± globose to pyriform, strongly papillate, black, leathery to carbonaceous, rough-walled, superficial, setose, solitary or weakly aggregated in small clusters; the ostiole conspicuous, periphysate. Subiculum absent at least at maturity, though the ascomata are formed on a small mat of very thick-walled dark brown hyphae. Peridium composed of an outer layer of very thick-walled dark brown cells intermediate between textura angularis and globulosa to ca 8 µm diam, with dark thick-walled setae 30-220 µm long scattered over the surface, and with a distinct and separable inner layer of very thin-walled strongly flattened hyaline textura angularis. Interascal tissue composed of thin-walled filiform paraphyses, usually deliquescent at maturity. Asci 65-90 x 9-12 µm, clavate, often rather long-stalked, thin-walled at all stages, the apex obtuse to rounded with an inconspicuous apical ring, 8-spored. Ascospores arranged biseriately, 10.5-14(-17) x 3.5-5 µm, ellipsoidal to fusiform-ellipsoidal, 3-septate, the septa hardly constricted and ± equally spaced, the middle cells golden brown and the end ones ± hyaline, smooth, thin-walled, without a mucous sheath.

Anamorph: unknown.
