Tiny discs, individually 0.1-0.2 mm diam., crustered in large, gregarious groups, stipes several times branched, concolorous pale yellow to yellow with short, apparently darekedning with age, short, straight hairs. On midribs of dead fronds of Cyathea.
Excipulum with short-cylindric cells, 3-5 µm diam., cell walls slightly thickened. Hairs about 40-50 x 2-3 µm, cylindric, undifferentiated to apex, finely roughened all over. Paraphyses 1.5 µm diam., undifferentiated at apex, about same length as asci. Asci 40-50 x 4-6 µm, subcylindric to subfusoid, taper gradually to more or less rounded apex, wall slightly thickened at apex, very faintly J+, croziers at base, 8-spored. Ascospores 6-9 x 1.5-2.5 µm (average 7.6 x 1.9 µm), oblong-elliptic, sometimes with widest point towards apical end, radially symmetrical, ends rounded, 0-septate.
