Anamorph: not known. Teleomorph: ascomata apothecia, immersed, opening by a pore but not becoming erumpent, at the surface 140-180 (-200) µm diam. with an opening 70-90 µm diam., the margin well-developed, entire, slightly protruding, white, crystalline. In vertical section 300-350 µm diam., ± globose, the disc deeply urceolate, grey when viewed from above. Exciple 40-50 µm thick, pale brown, strongly melanized at the base, composed of a single layer of thick-walled contorted and intertwined hyphae ca 2 µm diam., the upper part with massive ± hyaline crystalline inclusions. Periphysoids lining the upper and lateral parts of the exciple, to 20 µm in length. Subhymenium 12-15 µm thick, composed of small angular isodiametric cells, not staining in iodine. Paraphyses copious, filiform, septate, 1-1.5 µm diam., the apices only slightly and irregularly enlarged. Asci 230-270 x 4-5.5 µm, narrowly cylindrical, somewhat swollen in the central part when mature, not fissitunicate, the apex obtuse to rounded with an indistinctly refractive cap ca 2 µm thick, 8-spored. Ascospores helically coiled within the ascus, 300-320 x ca 1.5 µm, filiform, thin-walled, slightly tapering towards each end, hyaline, thin-walled, very indistinctly septate with cells 8-10 µm in length where visible, without a perispore, gelatinous sheath or appendages.
