Hymenophore annual, sometimes biennial, coriaceous, solitary, attached by a broad base. Pilei effused-reflexed, narrow reflexed margins arising from broadly resupinate areas, sometimes solitary when applanate or conchate, or as often resupinate, 5-25 mm wide, 5-15 mm radius, 2-7 mm thick, when resupinate ovate or linear, to 25 x 3.5 cm; pileus surface white, drying straw colour, vaguely transversely sulcate, even or slightly nodose, glabrous; without a cortex; margin abrupt, inturned, concolorous, crenate; hymenial surface cream or straw colour, even, with a more pallid margin 1-2 mm wide. Pores in section straw colour, round or angular, 4-6 per mm, 100-250 µm diameter, 1-4 mm deep; dissepiments 50-100 µm thick, equal, apices even. Context cream or straw colour, 0 - 2-1 mm thick, of densely intertwined hyphae ; binding hyphae to 3.5 µm diameter, walls to 1 µm thick, bovista type, branches tapering, aseptate; generative hyphae to 2 µm diameter, walls 0.1 µm thick, branched, septate, with clamp connections. Hymenial layer to 15 µm deep, a close palisade of basidia and paraphyses, soon collapsing. Basidia clavate, 10-12 x 5-6 µm, bearing 2-4 spores; sterigmata erect, to 5 µm long. Paraphyses subclavate, 8-10 x 4-5 µm.
