AC3C774354F29AF3739DF09B200B22CD.taxon	description	Description. Ascomata 125 - 185 (- 220) µm diam, globose to subglobose, scattered or clustered in small groups, immersed-erumpent, the base remaining immersed in the substrate, brownish black appearing black when dry, attached to subtending golden brown hyphae 8 - 22 µm diam, smooth, slightly constricted at septa; hyphae form cords developing under the wood surface and linking adjacent ascomata (Fig. 1 A-D); wood beneath ascomata or at the periphery of the colony stained purple; ostiole non-papillate, slightly depressed, pallid, rounded, minute, filled with hyaline periphyses (Fig. 1 F). Peridium appearing roughened by protruding cells (Fig. 1 B, D), 22 - 35 µm wide, two-layered: outermost layer textura angularis, composed of 1 - 2 rows of large thick-walled cells 8 - 18 µm in their greatest dimension, extending into hyphal appendages in places (Fig. 1 F), more pigmented in upper half, inwardly lined by smaller hyaline flattened cells forming a textura prismatica (Fig. 1 E, F). Asci 90 - 98 x 22.5 - 25 µm, bitunicate, with fissitunicate dehiscence occurring rarely, clavate to slightly obclavate, shortly pedicellate, 4 - 8 - spored, ascospores 1 - 3 seriate (Fig. 2 G-I); apex without (Fig. 2 J) or with a faint truncate ocular chamber (Fig. 2 K). Pseudoparaphyses 1 - 2.5 µm wide, cellular, often contorted, sparsely septate, rarely anastomosing, embedded in a gel matrix (Fig. 2 G, L). Ascospores (23) 24 - 28 (31) x (7) 8 - 9 µm, (mean = 26 x 8 µm; n = 60), ellipsoid-fusiform, 1 - septate, septum median to slightly submedian (0.53, N = 20), slightly constricted at the septum, upper cell wider and often apically pinched, lower cell obtusely rounded (Fig. 2 H, I, M), contents densely guttulate; wall medium brown, minutely verrucose with warts partially in contact and forming a loose reticulate pattern (Fig. 2 N), visible in hyaline immature ascospores; no sheath or appendages observed in aqueous nigrosin or India ink (Fig. 2 O).	en	Fournier, Jacques, Raja, Huzefa A., Shearer, Carol A.
