Original diagnosis: Pileus 51-76 mm diametro, hemisphaericus deinde convexus, tandem planus interdum in centro depressus, nitens, laevis usque leviter fibrillosus, viscidus, in centro caryophyllaceo-brunneus usque flavo-brunneus, versus marginem ita pallide. Lamellae sinuato-adnexae adnexaeve adnataeve, confertae usque ita moderate, lamellulatae, bubalino-caryophyllaceae deinde ita obscure, tandem interdum maculis brunneis. Stipes 44-76 mm longus cortinam evanescentem ferens, gracilis usque crassiusculus sed ad basim leviter tumidus vel bulbosus, laevis usque fibrillosus sed versus apicem farinosus solidus usque fistulosus, albidus, versus basim fuscus. Sporae 8.2-10.2 (= 9.1) x 4.8-5.8 (=5.3) μm, anguste ellipsoideae, verruculosae. Basidia non vidi. Cheilocystidia abunda, 34.4 x 9.2 μm, filiformi-ventricosa. Pleurocystidia nulla. Hyphae epicutis filamentosae, {42/2}, 2.4-6.4 (=4.1) μm diametro.

English translation: Pileus 51-76 mm in diameter, hemispherical then convex, finally applanate at times depressed in the centre, shining, smooth to slightly fibrillose, viscid, carnation-brown to yellow-brown, even if pale towards the margin. Lamellae sinuate-adnexed, or adnexed or adnate, crowded to moderately crowded, with lamellulae, buff-carnation, thereafter dusky, finally at times with brown spots. Stipe 44-76 mm long, bearing a vanishing cortina, thin to thickish but slightly swollen or bulbous at the base, smooth to fibrillose, but pulverulent towards the apex, stuffed to fistulose, whitish, very dark towards the base. Spores 8.2-10.2 (= 9.1) x 4.8-5.8 (= 5.3) μm. Narrowly ellipsoid, verruculose. Basidia not seen. Cheilocystidia abundant, 34.4 x 9.2 μm, filiform-ventricose. Pleurocystidia none. Hyphae of epicutis filamentous, {42/2}, 2.4-6.4 (=4.1) μm wide.
