Description: | Ascomata 1000-1200 μm high, 1700-1800 μm wide, 350-370 μm thick, subglobose in frontal view, fusiform in sagittal section, immersed in a black stroma, with a longitudinal furrow at the top, ostiolate, carbonaceous to coriaceous, black, gregarious, ostiolar canal with septate periphyses. Pseudoparaphyses 1-2 μm in diameter, trabeculate, unbranched at the base becoming branched and anastomosing above the asci. Asci 280-420 × 24-32 μm, eight-spored, cylindrical, long pedunculate, thick-walled, bitunicate, with an apical plate and a refractive ring in the endoascus, rings 10-12 μm in diameter, 3-4 μm thick, not bluing in IKI. Ascospores 46-68 × 16-25 μm, uniseriate, ellipsoidal to broadly fusiform, muriform, with (9-) 10-11 (-12) transsepta and 1-3 longisepta in all but the end cells, slightly constricted at the septa, yellow-brown but hyaline to light brown in apical cells, with a gelatinous cap around apical and subapical cells. | |||
