lignicola

Sexual morph: Ascomata 170-350 μm high, 120-250 μm diam., globose, subglobose or ellipsoidal, immersed, partly immersed or superficial, ostiolate, papillate, membranous, and pale to dark brown. Necks (48-)80-165 μm long, up to 72 μm diam., brown, with periphyses. Peridium Brown, one-layered, composed of several layers of thick-walled angular cells forming textura angularis. Paraphyses present, but sparse. Asci 100-(128)-180 × 16-24 μm, eight-spored, cylindrical or clavate, short-stalked, unitunicate, persistent, with an apical truncate non-amyloid apical thickening containing a pore. Ascospores 24-36 × 8-12 μm, uni- orbiseriate, ellipsoidal, tri-septate, not markedly constricted at the septa, central cells brown (10-6-16 μm), apical cells smaller and hyaline (2.6-6 μm). Anamorph Undetermined.
