description
Culture characteristics. Conidia germinating on WA within 12 h and germ tubes produced from the basal end. After transfer to the PDA, the colonies grew rapidly, reaching 5 cm diam. in 1 week at 25 ° C. Part of the mycelia grew on the surface of the medium, compact, violet, with a light-colored rim, and part of the mycelia remained immersed in the medium. The central area of the colony on the back was reddish-brown, the middle white, and the edge light-colored.

diagnosis
Diagnosis. Saprobic on decaying wood in terrestrial habitats, and immersed in host epidermis. At maturity, the fruiting body breaks through host epidermis. Sexual morph: undetermined. Asexual morph: Conidiomata dark brown to black, pycnidial, solitary to gregarious, globose to subglobose, apapillate, ostiolate. Conidiomatal wall comprising several layers of cells of textura angularis, with inner layers comprising hyaline to dark brown and outer layers composed of dark brown to black cells. Conidiogenous cells 11 – 27 × 3 – 5 μm (av. 21 × 4 μm, n = 20), hyaline, enteroblastic, phialidic, with minute collarette, doliiform, ampulliform, arising from the innermost layer of the pycnidial wall, intermixed with hyaline, filamentous, septate paraphyses. Conidia 12 – 15 (- 23) × 2 – 4 μm (av. 14 × 3 μm, n = 30), hyaline, smooth, cylindrical to subcylindrical or fusiform, straight or slightly curved, aseptate, guttulate at both ends.
