Ascomata superficial, turbinate with a broadly sterile base from which a few hyphal strands penetrate into the underlying wood, scattered or gregarious and basally adnate, coarsely tuberculate on the surface, rarely collapsing on drying, non-ostiolate, up to 1040 μm high and 741 μm wide. Peridium of two layered, pseudoparenchymatous, externally composed of brown, thick-walled, large cells with Munk pore between adjacent cells, extending below to form a sterile base, internal cells are hyaline, thin-walled and compressed. The apical region in the centrum is composed of dome-like Quellkörper which is made up of thin-walled, concentrically arranged cells in a mucilaginous matrix. Asci deliquescing early, unitunicate, arising from a basal cushion, clavate, 8-spored, 190-286 × 16-23 μm, long-stalked up to 128 μm. Ascospores irregularly fasciculate in asci, hyaline, allantoid, rounded to acute in each end, mostly 1-septate, rarely 2 or 3-septate, 38-69 × 7-10 μm.

Note：
This species is very common in Europe (Dennis, 1978:Müller & v. Arx, 1962) and America (Corlett & Krüg, 1984), and also reported in China (Eriksson and Yue, 1988). This species usually does not collapse at the apex on drying (Nannfeldt, 1975), but the Taiwan species occasionally collapsed to form cupulate ascomata.
