Anamorph: not known. Teleomorph: ascomata apothecia, gregarious, rarely confluent, superficial, to 800 µm diam. when fresh, mostly 50-200 (-300) µm diam. when dry, cyathiform to cupulate when young, cupulate when mature, ± sessile with a slightly tapering base. Disc shallow to plano-convex and pure white to watery greyish when fresh, bordered by a thin zone of marginal hairs which rise only slightly above the hymenium. Margin fleshy and incurved when dry, typically obscuring the hymenium. Hair cover dense at margin, sparse to dense below, snow-white. Ectal excipulum of prismatic cells, not notably changing shape towards the margin, at the base more rounded. Inner excipulum of narrower prismatic cells. Hairs 30-50 x 1.8-5.0 (-8.0) µm, varying between populations from almost filiform or narrowly conical to slightly lageniform, straight to bent, undulating or not but never apically recurved, aseptate. Marginal hairs intermixed with abundant, cylindric-clavate thin-walled cells, 10-30 x 3-5 µm in size. Interascal tissue of filiform paraphyses, cylindrical to slightly widened at the apex, sometimes branched below. Asci arising from croziers, 34-63 (-74) x 6-9 (-10.5) µm, cylindric-clavate, with a short broad slightly tapering stalk, thin-walled, apex obtuse, with an apical pore blueing in iodine, 8-spored. Ascospores 8.5-14.5 (-15.5) x 2.5-4 µm, ellipsoidal to cylindric-ellipsoidal, with rounded to slightly tapered apices, frequently one-septate after being discharged, more rarely while still inside the asci, hyaline, occasionally brownish in aged discharged spores. Guttules prominent in fresh material, appearing either as one large globule at each end or as abundant, smaller, apically grouped globules.
