Type Information: Basionym: Uncinula septata E. S. Salmon. Type: Uncinula septata E. S. Salmon.

Taxonomic Literature: Taxonomic notes: +ascocarp outer wall cells obscure, irregularly polygonal to rounded, ca. 6-15 µm diam., somewhat radiately arranged;. Braun U., Beih. Nova Hedwigia 89: 1-700 [464] (1987).

Biogeography: Continent: Asia-Temperate. Region(s): China. Country or state(s): Japan.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Cleistothecioid, orbicular, forming independently from the host thallus or mycelium, scattered, (.13)-.15-.23 mm in diam.. Margin: External filaments present (shorter than the cleistothecial diam., width subequal throughout); uncinate (closely), circinate, or helicoid (sub-), 3-8 µm in diameter, hyaline or pigmented (in the lower half, brown), very numerous, 50-200 per mm², growing on the upper half of the ascocarp (densely crowded), flexuose (somewhat) or stiff and straight (fairly), smooth, thin, not ramified, septate (ca. 5-11 septa, septate from base to top, septa often reaching the upper half, even the circinate part).

Asci: 6-15 asci per ascocarp, indistinctly stipitate (shortly stalked, rarely subsessile), 45-95 µm long, 25-45 µm wide; dehiscence unitunicate (asci mostly immature).

Ascospores: c. 4 or c. 8 per ascus, spores 4-8 per ascus, curved (to comma-shaped), 30-38 µm long, 10-15 µm wide; septa absent.
