Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Cleistothecioid, orbicular, forming independently from the host thallus or mycelium, scattered or in loose groups, .09-.12 mm in diam.. Margin: External filaments present; recurved (very rarely few tips slightly recurved, tips obtuse) or straight, 1-1.5 µm long, hyaline or pigmented (brown near the base), few or numerous, 8-18 per mm², growing more or less between the lower and upper hald of the ascocarp, more or less stiff and straight, smooth, thin or thick (towards the base), ramified, dichotomously branched (4-6 times, mostly rather regular and compact, sometimes primary branches elongated, branchings looser, rarely deeply cleft, tips of the ultimate branchlets straight, very rarely few tips slightly recurved, tips obtuse, ultimate branchlets cylindric to clavate, rarely pointed), aseptate or septate (0-2-septate).

Asci: 4-8 asci per ascocarp, indistinctly stipitate, 40-65 µm long, 24-45 µm wide; dehiscence unitunicate.

Ascospores: 1–2, c. 4, or c. 8 per ascus, spores (2)-3-6 per ascus, subglobose, ellipsoid, or ovoid, 16-25 µm long, 10-16 µm wide; septa absent.
