Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Cleistothecioid, orbicular, forming independently from the host thallus or mycelium, scattered or in loose groups, .085-.13-(.14) mm in diam.. Margin: External filaments present (width variable, subequal throughout or somewhat increasing upwards, but apex usually not enlarged, appendages sometimes increasing (1/2-2/3 of the stalk) and then narrowing towards the apex, appendages often collapsed in places); circinate (closely) or sub-helicoid, (1)-1.5-2-(2) µm long, 4.5-8-(11) µm in diameter, hyaline or pigmented (at the very base), numerous, (10)-20-40-(45) per mm², growing between the lower and upper hald of the ascocarp, flexuose (curved, subundulate, rarely straight and stiff), stiff and straight, or sub-geniculate (bent), smooth or rough, thin or moderatly thick (towards the base, or thin-walled throughout), not ramified, aseptate or septate (with a single septum at the base).

Asci: 5-16 asci per ascocarp, not stipitate or indistinctly stipitate, 40-65 µm long, 25-45 µm wide; dehiscence unitunicate (immature).

Ascospores: c. 4 or c. 8 per ascus, spores (4)-5-6-(7) per ascus, ellipsoid or ovoid, 16-25 µm long, 10-15 µm wide; septa absent.
