Description: STROMA substratal, thin, black, crustaceous. APOTHECIA solitary gregarious, stipitate, arising from conspicuously stromatized portions of the substrate. DISC 2-7(-10) mm diam., smooth, concave and black when dry, rehydrating dark brown, plano-convex. RECEPTACLE cupulate to discoid, pale brown, paler, milky-coffee colour at the margin, darker towards the stipe, often radially streaked or furrowed, smooth or minutely downy. STIPE central, tapered, variable in length, 1-6(-15) mm. long, yellowish-brown or dark-brown, blackish at the base, smooth or basally tomentose. ASCI 8-spored, cylindric-clavate, tapered below to a small foot 3.5-4.5 µm diam., apex rounded or rounded-truncate, pore outlined strongly blue in Melzer's reagent, the base of the pore usually more deeply coloured, (95-)105-120(-132) x 7-9(-10) µm. ASCOSPORES ellipsoid, ellipso-fusoid or ovate-ellipsoid, often inequilateral, flattened or concave on one face, ends rounded, narrowed and rarely pointed distally, non-septate, usually becoming pale brown whilst still within the ascus, biguttulate, the guttules obscured after pigmentation, wall smooth or very finely punctate, obliquely uniseriate or biseriate above, measuring 9.5-12.0 x 4.0-5.0, mean 10.7 (SD 0.6) x 4.7 (SD 0.3) µm (Whetzel S1O1O); 11.0-13.0 x 5.0-6.0, mean 11.8 (SD 0.7) x 5.4 (SD 0.3) µm (Beaton 106). PARAPHYSES filiform, obtuse, hyaline, slightly exceeding the asci, straight or flexuous, simple or often lobed in upper part, branched below, 1.5-2.0 µm diam., not or slightly enlarged towards the apex to 2-3 µm diam. ECTAL EXCIPULUM composed of a textura prismatica, the cells arranged in rows at a low angle to the surface, pale-brown, running out at the surface in the upper part of the receptacle and especially towards the margin as obtuse, hair-like extensions, 0-1-septate, 30-60 x 6-10 µm. MEDULLARY EXCIPULUM strongly amyloid, composed of subhyaline or pale brown loosely interwoven thin walled, septate hyphae. SUBHYMENIAL not always clearly distinct, approximately 15-25 µm deep, of narrow, closely woven hyphae, nonamyloid.
