MycoBank number: MB 521660; Index Fungorum number: IF 521660; Facesoffungi number: FoF 12606.
Saprobic on soil. Sexual morph: Apothecia 0.2−0.5 cm broad, 500−800 µm high, scattered to gregarious, golden yellow or yellow-orange when fresh, brown when dry, with brown, rigid, straight, tapering hairs, sessile. Receptacle concave, receptacle surface golden yellow or yellow-orange, concolorous with the hymenium, covered brown setae, margin conspicuous, entire with hairs. Hymenium yellow. Ectal excipulum 120−220 µm, of textura angularis to textura globulosa, hyaline, inner cells 33−45 × 20−34 μm; outermost cells 46−66 × 23−35 μm, elongate to forming hyaline hypha hairs (rooting hairs), especially close to base, 7−12 μm; with 150−600 μm long, dark brown, septate, setose hairs with simple or furcate base, and pointed end. Medullary excipulum 150−600 μm, composed of textura intricata, 5−7 µm broad hyaline hyphae. Paraphyses 2−4 µm broad, filiform, with yellow pigments, exceeding the asci slightly, apex enlarged, 5−8 µm broad. Asci 189−223× 11−13 μm, 8-spored, cylindrical, operculate, inamyloid. Ascospores [20/1/1, in H2O] (14.5−) 15.2−16.8 (−17.6) × (8.7−) 9.3−10.7 (−11.1) (Q = 1.41−1.87, Q = 1.60±0.12) (excluding ornamentation), ellipsoid, hyaline, uniseriate, equilateral, rounded at the ends, biguttulate, ornamented with rounded or irregularly warty, partly interconnected to form a network. Asexual morph: Unknown.
