Diagnosis Apothecia 2,5-6 mm diam., solitaria, orbicularia, breviter crasseque stipitata, molliter carnosa; thecium patellare, mox planum, denique usque pileatum, laeve, sat pallide castaneo brunneum, margine anguste submembranaceo-limbato, minute obscureque denticulato vel lacerato; stratum externum excipuli stipitisque cum thecio concolor, sparse umbrino-tomentosum; stipes usque ad 1,5 mm longus, crasse cylindraceus, basi hyphis hyalinis substrata affixus. Excipulum e cellulis subglobosis vel late ellipsoideis, 12-28 µ latis, pallide brunneolis, sat tenuiter tunicatis; stratum externum hyphis laxe intricatis, longe cylindraceis, flexuosis, septatis, pallide brunneis, 3-5 µ crassis (membranis 1-1,5 µ crassis), obtuse terminatis tectum est; limbus e hyphis similibus instructus est.
