Saprobic on dead wood. Sexual morph: Apothecia up to 8 mm broad, 3 mm high, scattered to gregarious, with brown, rigid, straight, tapering hairs, sessile. Receptacle discoid to concave, receptacle surface orange-brown, slightly daker than hymenium, covered brown setae, margin conspicuous, entire with hairs. Hymenium orange. Ectal excipulum 60−100 µm, of textura angularis to textura globulosa, 22−28 × 14−17 μm cells, hyaline to yellowish, outermost cells elongate to forming brownish hypha hairs (rooting hairs), especially close to base, 7−13 broad μm; with 140−300 μm long, 10−16 μm broad closed to base, dark brown, septate, setose hairs with simple base, and pointed end. Medullary excipulum 80−130 μm, composed of textura intricata, 3−7 µm broad hyaline hyphae. Paraphyses 2−3 µm broad, filiform, hyaline, exceeding the asci, apex enlarged, 6−9 µm broad. Asci 229−254× 13−16 μm, 8-spored, cylindrical, operculate, inamyloid. Ascospores [20/1/1, in H2O] (17.8−) 18.0−20.1 (−21.8) × (10.6−) 10.9−12.5 (−13.6) (Q = 1.51−1.79, Q = 1.63±0.09) (excluding ornamentation), ellipsoid, hyaline, uniseriate, equilateral, rounded at the ends, uniguttulate to biguttulate, ornamented with rounded or irregular warts, partly interconnected to form a network. Asexual morph: Unknown.
