Capronia pilosella (Karst.) E. Müller, Trans. Br. Mycol. Soc. 88: 63. 1987.

 Description: Ascomata superficial on decorticated bark, globose or compressed globose, 146-165 μm in diam., gregarious sometimes grouped adnate or scattered, seated on a basal subiculum which form loose hyphae penetrating the underlying cells, setose around the surface of the wall, setae up to 60 μm. Peridium 18-29 μm thick, composed of 8-12 layers of pseudoparenchymatous cells, brown, compressed inside and becoming blackened and polygonal outside. Asci broadly cylindrical, bitunicate, 8-spored, basal, 42-74 × 8-10 μm, with sparse pseudoparaphyses which usually disappear at maturity. Ascospores grayish-brown, broadly elliptical, uniseriate to biseriate, muriform, with 3 to 7 transverse septa, slightly constricted, and up to 3 longitudinal septa, 11-16 × 4-6 μm.

 Note: The ascospores of Taiwan specimens examined have more transverse and longitudinal septa than the species described by Müller & Petrini (1987). In culture, it produced a Cladosporium-like anamorph as reported by Müller & Petrini (1987).
