Odour and taste mild. Latex absent. Peridiopellis 50-65 µm wide, a trichodermium of 5-8 tiers of cells 5-7.5 x 6-12 µm, with patches of upright hyphal tips 7-10 x 3-4.5 µm which collapse to form an amorphous tan-brown to golden layer. Peridial context 45-150 µm wide, of interwoven, ± parallel, hyaline hyphae 2-3 µmdiam., with some scattered, refractive, inflated elements 5-7 µm diam. Endocystidia and sphaerocysts absent. Stipitipellis 11-18 µm wide, an ixocutis of compacted hyphal tips 2-4 µm diam. Stipe context of interwoven, hyaline hyphae 2-4 µm diam. Hymenophoral trama 12-23 µm wide, of loosely interwoven hyphae 2-3.5 µm diam. and infrequent, elongated inflated elements, 4-7 µm diam., sphaerocysts absent. Subhymenium 9-15 µm wide, with 1-2 tiers of isodiametric cells 5-11 µm diam. Basidia 25-37 x 10-12.5 µm, clavate, hyaline, with 2 and 4 slender to robust sterigmata 5-7.5 µm long. Cystidia 42-75 x 9-11 µm, clavate to cylindrical, though usually tapered slightly at base, with granular contents; arising at base of the subhymenium, scattered. In young specimens, maybe abundant. Spores 9-11 x 8-10.5 µm (9.79 ± 0.48x 8.96 ± 0.51), Q = 1.06-1.11, subglobose, orthotropic. Ornamentation amyloid, crowded, of isolated spines 1-2 µm high, narrow to robust, straight or curved. Hilar appendix central, straight, prominent, 1.5 x 2 µm; plage absent. Spore colour in mass white.
