A later homotypic synonym is: Meliderma crassum (Fr.) Velen., Ceské Houby 2: 400 (1920).
Original diagnosis: Cortinarius crassus, pileo crasse carnoso plane depressoque unicolori, disco glabro, ceterum fibrillis innatis strigoso, stipites valido obeso fibrilloso albo, apice albo-farinaceo, lamellis rotundatis confertis integerrimis e pallido argillaceis. In nemoribus humidis raro. Valde notabilis, curtus, robustus, sed caro mollis pallescens. Pileus 3-5 unc. latus, sordide luteus, opacus, nec nisi disco primitus viscidulus. Videtur hinc ad Inolomata pertinere, sed ex affinitate proximus intime connexus, utrumque velum saepe obsoletum.
English translation: Cortinarius crassus, pileus thick-fleshed, plane, depressed, unicoloured, with glabrous disc, but strigose with innate fibrils; stipe really thick white fibrillose, with white farinaceous apex; lamellae rounded, crowded, entire, pale then clay-coloured. Rare in moist forest. Indeed striking, shortish, robust, but with soft, pallescent context. Pileus 7.5–12.5 cm broad, sordid yellow, opaque, not viscid or at first at disc only. It seems to belong to Inoloma, but of close affinity to the next [C. balteatus], both have rudimentary veil.
