Lamellae almost free, ventricose, white then almost purely pink with concolorous, entire edge. Stipe 30-45 x 1-2 mm, cylindrical, sky-blue when young, soon becoming pale grey, smooth, polished, base white tomentose. Context pallid. Smell and taste indistinct.
Spores 9.0-12.0 x 7.5-9.5 µm, average 10.6 x 7.9 µm, Q = 1.1-1.3-1.5, heterodiametrical, 5­8-angled in side-view. Basidia 23-40 x 7.5-12 µm, 4-spored, clampless. Lamella edge usually entirely sterile, sometimes heterogeneous, with dense clusters of cystidia mixed among fertile basidia. Cheilocystidia 24-70 x 6-15 µm, cylindrical to clavate. Hymenophoral trama regular, made up of cylindrical to inflated hyphae, elements 110-300 x 4-20 µm. Pileipellis a cutis of cylindrical, 4-15 µm wide hyphae with scattered trichodermal tufts of ascending, clavate terminal elements, 20-70 x 12-22 µm. Pigment brownish, intracellular in pileipellis.
