Index Fungorum number: IF 483979; Facesoffungi number: FoF 09158 , Fig. 1
Description:
Saprobic on decaying branch. Sexual morph: Ascomata 235–255 μm diam., 195–230 μm high, globose to broadly ellipsoidal, papillate, appearing pale brown when young or dark brown on maturity. Peridium 25–35 μm membranous, one-layered comprising cells of textura angularis-globulosa, in vertical section cells rounded to elongate. Hamathecium 1–1.5 μm comprising cellular pseudoparaphyses, septate, sparsely branched, up to 2.0 mm wide. Asci 140−165 × 30−45 µm (x̄ = 152.2 × 38.3 µm, n = 10), eight-spored, clavate, bitunicate, fissitunicate, with thickened apical region, spores variably arranged, with a small distinct ocular chamber. Ascospores 56−62 × 19−22 µm (x̄ = 58.2 × 20.5 µm, n = 10), multi-seriate, one-septate, constricted at the septum, lower cell slightly longer and narrower than upper cell, smooth, pale brown, sometimes guttulate, sheathed. Sheath appressed to the wall. Asexual morph: Unknown.
Material examined: Thailand, Khao Yai National Park, on decaying branch, July 1998, leg. A. M. Abdel-Wahab (UBC F13875, holotype).
