MycoBank number: MB 358476; Index Fungorum number: IF 358476; Facesoffungi number: FoF 12597;
Saprobic on sandy soil. Sexual morph: Apothecia 2−15 mm broad, 1−2 mm high, scattered to gregarious, sessile, pubescent. Receptacle discoid to shallowly saucer-shaped, receptacle surface red brown, darker in color than hymenium, covered setaceous hairs, margin conspicuous, entire. Hymenium orange to red, nearly smooth. Ectal excipulum 70−270 µm, composed of textura angularis to textura globulosa, 29−37 × 24−30 μm cells, hyaline to brownish, with 55−140 μm long, 5−11 μm broad setaceous hairs, brown, septate, rounded end. Medullary excipulum 60−170 μm, composed of textura intricata, 5−10 µm broad hyaline to brownish hyphae. Paraphyses 2−4 µm broad, with yellow to brownish pigments, filiform, exceeding the asci, apex enlarged, 5−7 µm broad. Asci 216−245 × 11−14 μm, 8-spored, cylindrical, operculate, inamyloid. Ascospores [20/1/1, in H2O] (16.1−)16.6−18.5(−20.0) × (9.1−)9.7−10.6(−10.9) μm (Q = 1.52−1.96, Q = 1.73±0.10) (excluding ornamentation), ellipsoid, uniseriate, equilateral, rounded at the ends, biguttulate, cyanophilous ornamented with raised reticulum. Asexual morph: Unknown.
