Diagnosis Apothecia 3–10 mm diam., disciformia, sessilia, disco aurantio-luteo vel vivide rubro, margine extusque pilis fasciculatis, brevibus, brunneolo-coloratis dense vestita. Excipulum externum cellulis plus minusve globosis vel late ellipsoideis usque ad 30 µm diam., sed etiam 40 × 25 µm vel 60 µm diam., subhyalinis, subcrasse tunicatis instructum. Pili 150–250 (–300) × 4–9 µm, subcylindracei, recti, apice obtuse attenuati, plerumque non dilatati nec acuti, parte basali simplices, non radicati, e cellulis superficialibus oriundi, septati, pallide brunnei, parte superiore nonnumquam pallidiori usque subhyalini, tunica subincrassata (1.5–2 µm). Insuper pili toti ecolorati breviores in parte externa excipuli observati erant. Asci 240–290 × 13–14 µm, cylindracei, octospori, sporis distichis. Paraphyses numerosae, filiformes, 1.5–2 µm crassae, apice rectae atque parum dilatatae (3–5 µm), ecoloratae, in strato citrino-luteae. Ascosporae 19–22 × 10.5–12 µm, oblongo-ellipsoideae, guttulis 1–3 maioribus (plerumque binis) instructae, ecoloratae, laeves. Hab.
