Diagnosis Ascomata superficialia, solitaria vel saepius gregaria, 0,5-5 mm diam., sessilia vel aliquando substipitata, subglobosa ab initio vel columnaria, usque ad turbinata, deinde orbiculata vel pulvinata vel etiam scutellata, membranacea, aliquando irregulari, initio involuto, deinde applanato, prominenti margine praedita. Receptaculum furfuraceum usque ad tomentosum, griseopallidum vel albidogriseum. Discus plus minusve concolor, fere concavus ab initio, deinde planus vel convexus, ex protrudentibus ascis granulatus.

Excipulum ectale e textura globulosa-angulari, cum porrecta permixta, constitutum, cum rotundis vel angulatis, 9-25 × 5-14 µm, ad marginem cylindratis vel claviformibus cellulis. Paraphyses uniformes, filiformes, 1-2 µm diam., simplices vel furcatae, hyalinae, ascos excedentes, non- vel vix ad apicem inflatae. Asci copiose iodo caerulescentes, 250-300 × 19-27 µm, operculati, octospori, cylindrati, longicaudati. Sporae monostichae, (23,7-) 24,7-29 (-30) x 12,3-14 µm, anguste ellipsoideae (Q = 1,78-2,30; Q = 2,01), plerumque aequis lateribus constitutae, leves, hyalinae, crasse tunicatae, apiculatae, concrescente materia seorsum cinctae.
