Basidiomata 3-35 x 3-25 mm, subglobose to lobed. Peridial surface dry, smooth, white with pale yellow to orange brown patches. Gleba white, loculate, chambers small and crowded. Stipe rarely present as a small exerted basal pad 1-2 x 1-2 mm, easily detached from basidioma. Columella rarely present as a thin translucent, percurrent strand, ± 1 mm wide. Odour slightly acrid, and taste not distinctive. Latex absent. Peridiopellis 8-20 µm wide, a patchy turf of upright to repent, hyaline hyphal tips 2-4.5 µm diam., becoming gelatinised and compacted in older basidiomata. Peridial context 115-210 µm wide, of tightly interwoven, hyaline hyphae 2-3.5 µm diam., sometimes in tight knots, and scattered, inflated hyphae 3-8 µm diam., refractive golden in KOH. Endocystidia and sphaerocysts absent. Hymenophoral trama 18-40 µm wide, of interwoven, hyaline hyphae 2-5 µm diam. and scattered thin, smooth, sinuous hyphae 2-3 µm diam., refractive in KOH, sphaerocysts absent. Subhymenium 11-28 µm wide, with 2-3 tiers of irregular cells 7-15 µm diam. Basidia 28-41 x 7-11 µm, cylindrical to clavate, hyaline, with 2, 3, or 4 sterigmata 4-7 µm long. Cystidia 11-35 x 5-9 µm, cylindrical, clavate or fusoid with mucronate or obtuse apices and granular contents; scattered to patchily abundant, arising in the trama, not protruding beyond basidia. Spores 8.5-11 x 7-10 µm (9.73 ± 0.27 x 8.83 ± 0.54), Q = 1.02-1.09, globose to subglobose, orthotropic. Ornamentation amyloid, of abundant isolated warts 0.5-0.8 µm high, many connected in short branched lines, sometimes forming a partial reticulum. Hilar appendix central 1-2 x 1-2 µm; plage absent. Spore colour in mass off-white.

HABITAT AND DISTRIBUTION: Hypogeous to partially exposed, in small groups under leaf litter in Nothofagus menziesii and N. solandrii forests. Fruiting period May-Sep.

Peridiopellis ex hyphis erectis vel repentibus, agglutetibus compactis ubi veteribus. Basidia 28-41 x 7-11 µm, 2 vel 4 sporigera. Cystidia 11-35 x 5-9 µm, dispersa. Sporae 8-11 x 7-10 µm, globosae vel subglobosae, amyloideae verruculis segregatis < 0.5 µm altis, lineis brevis ramosis interdum connexis vel reticulatis partiali ornatae.
