Anamorph: not known. Teleomorph: stromata absent. Ascomata scattered or in small clusters, visible externally as shallowly conical dark brown clypeus-like structures 500-650 µm diam. with hardly papillate ostioles, covering a single ascoma. Ascomata 400-600 µm diam. and 350-450 µm tall, subglobose, with a short neck, the ostiole lined with periphyses. Peridium 20-30 µm thick, composed of an outer layer of dark brown angular cells and an inner layer of hyaline flattened tissue. Interascal tissue of unbranched thin-walled paraphyses 2.5-3 µm diam., immersed in copious mucous gel. Asci 130-160 x 14-17 µm, cylindrical to cylindric-clavate, with a fairly short tapering stalk, the apex obtuse, fairly thick-walled but not fissitunicate, with a very large conspicuous J+ apical truncated-conical ring structure to 6 µm diam. and 8 µm tall, 8-spored. Ascospores biseriately arranged, 21-23.5 x 7.5-8.5 µm, fusiform-ellipsoidal or sometimes narrowly clavate, often slightly inaequilateral, initially hyaline but becoming dark chocolate brown at maturity, distinctly constricted at the ± median septum, smooth and very thick-walled, each cell with four pale longitudinal germ slits extending almost the length of the cell, covered with a thick hyaline gelatinous sheath.
