Index Fungorum number: IF 302844

Saprobic on dead wood. Sexual morph: Ascomata 0.5−2 mm high, 4−12 mm broad, superficial, scattered, substipitate, orange. Receptacle orange, cupulate to saucer-shaped when young, saucer-shaped to irregular when mature, margin conspicuous when fresh, margin involute, hymenium reddish to orange, receptacle surface yellowish, wrinkled when dry. Medullary excipulum 273−656 μm broad, of textura intricata, hyaline, composed of 2−4 μm broad hyphae. Ectal excipulum 49−114 μm broad, of textura porrecta, hyaline to brown, composed of 3−6 μm broad hyphae, J-. Paraphyses 2−3 μm broad, filiform, exceeding the asci, pigmented, yellowish contents, septate, branched, J-. Asci 157−195 × 9−11 μm (Hansen et al.: 170−200 μm; Le Gal: 175−280 μm; Wang: 200−225 × 12–15 μm), 8-spored, operculate, subcylindrical, stipitate, J-. Ascospores [20/1/1, in H 2 O] (15.0–)17−20 (–22.3) × (7.9–)9−11(–11.1) μm (Q = 1.72−2.06, Q = 1.89±0.17), ellipsoid with rounded ends, uniseriate, inequilateral, uniseriate, inamyloid, uniguttulate or biguttulate, smooth or very faint striations, rare ascospores with gelatinous sheath in 5% KOH. Asexual morph: Unknown.

Material examined:— THAILAND, Ranong, on unidentified dead wood, 5 October 2017 ; M. Zeng, ST03 ( MFLU 18-0713 , HKAS 97491 ) .

Note: This species is characterized by yellowish paraphyses and guttulate ascospores with faint striations. The first description of this species was by Le Gal (1953) and the first record from Thailand was by Hansen et al. (1999). Remarkably, there are no publications mentioned whether this species have a sheath surrounding the ascospores. Ascospores surround by a gelatinous sheath was observed in our collection ( MFLU 18-0713).
