Diagnosis Ascocarpium superficiale, 0.4-1 mm latum. 0.4-0.6 mm altum, primum turbinatum vel pyriforrne vel subglobulare, deinde saepe in formam discoidem expansum, albidum vel pallide fuscidum, extra glabrum. Excipulum exterius omnino 20-35 µm crassum, textura angulari vel globulosa, cellulis 10-25 µm diam., parietibus tenuibus. Excipulum medullare e cellulis parvis, densissime intertextis compositum parietibus tenuibus; subhymenium paulum manifestum. Hymenium 285-300 µm altum. Asci cylindrici, maturi 380-445 × 30-33 µm magni, valde prominentes, parietibus in liquore Melzeri paulum amyloides se praebentibus. Paraphyses hyalinae, ramificatae, septatae, 2-3.5 µm crassae. Sporae in parte superiore asci in binas series vel irregulariter dispositae, 21.5-22.6-23.3 × 9.9-10.6-11.2 µm magnae, primum hyalinae, deinde dilute purpurascentes, demum fuscide vinaceae, rimis paucis longitudinatibus, saepe ramificatis fissae, tunicis gelatineis unilateralibus manifestis. – Figg. 2-4.
