Description: | Colonies epiphyllous, up to 5 mm in diam. Hyphae forming a loose network, growing radiately, brown. Hyphae cells 27-42 × 5.5-8.7 μm with capitate and few mucronate hyphopodia. Capitate hyphopodia growing near hyphal septum, alternate, short, 19-23 μm long, 1-septate, with a swollen terminal cell, oval to subglobose, 12.6-16.6 × 10-14 μm. Mucronate hyphopodia alternate or opposite, near to hyphal septum, 1-celled, with a broad base, straight or curved with a terminal pore, 12-23 μm long, 6-8.7 μm wide at base. Ascomata developing in center of the colony, globose, 99-142 × 83-114 μm, with verrucose surface cells. Surface cells obtuse conoid, with a flattened base, 16-31 μm high. Asci often evanescent. Ascospores 37-44 × 13.4-19.7 μm, oblong to broadly ellipsoid, ends rounded, first hyaline then becoming brown at maturity, smooth, 4-septate, constricted at septa. | |||
