SUMMARY
Anamorph: not known.
Teleomorph: stromata absent. Ascomata apothecia, singly or in clusters, 2-8 mm diam., discoid with a slightly raised margin, the hymenium brownish orange to red, surrounded by short setae that also clothe the outer surface. Setae uniformly mid brown, 100-300 (-400) µm long and usually rather even in length, 15-35 µm diam. near the base which is sometimes attenuated and may be simple, bi- or trifurcate; 1- to 4-septate, flexuous and often slightly constricted at the septa; accompanied by dense clusters of blunt ± hyaline hyphae that form a raised margin surrounding the hymenium. Interascal tissue of simple or branched paraphyses 2.5-3.5 µm diam., expanded at the apex to 8-12 µm diam., filled when fresh with orange carotenoid pigments. Asci 190-250 x 13-19 µm, cylindrical, gradually narrowing to a short stalk, fairly thick-walled but not fissitunicate, the apex rounded and not thickened, operculate, not staining in iodine, 8-spored. Ascospores arranged ± uniseriately, 15.5-19 x 8-11.5 µm, ellipsoidal, hyaline, aseptate, thick-walled, with an outer perispore layer that loosens when heated in lactic acid/cotton blue, covered in inconspicuous rounded to elongate warts to 1.5 µm broad and 0.5 µm high, often coalescing to form irregular ridges, unevenly distributed with some parts of the perispore almost smooth; without a gelatinous sheath or appendages.
