Types: Junghuhnio, Linnaea 5: 807 (1830) tab. 6 fig. 8, lectotype (icon) designated by Beker et al., Hebeloma (Fr.) P. Kumm.: (2016) page 643 (MBT203033)

The lectotype (icon) is described from Southern Germany.

Original diagnosis: Sporidiis nullis, velo fibrilloso, pileo carnoso acute convexo glabro violaceo, lamellis liberis angustis crassiusculis brunneis, stipite aequali solido violaceo sursum pruinoso basi substriato. Tab. VI, f. 8. Elegans. Velum fibrillosum, fugax. Sporidia non vidi, licet haud exiguam individuorum copiam chartae imposuerim! Pileus convexus, acutus, (subumbonatus,) unciam circiter latus, carne alba. Lamellae simplices, inaequalis, crassae, subliberae, utrinque aequaliler attenutae, dorso rectae, brunneae, cervinae, lineam, vix ultr., latae. Stipes 2 lin. crassus, 1 -1½ unc. longus, apice floccoso-pruinatus, deorsum e venis homogeneis substriatus. Odor saporque nulli. Inv. solitarium in sylvis Hercyniae ad Harzgerode, Falkenstein, passim. Septbr. - Octbr.

English translation: Spores absent, veil fibrillose, pileus fleshy, acutely convex, glabrous, violaceous, lamellae free, narrow, thick, brown. Stipe equal, solid, violaceous, apex pruinose, striate towards base. Tab. VI, f. 8. Elegant. Velum fibrillose, fugacious. Spores not seen, possibly too sparse to set on paper [spores too few per specimens to make a spore print]. Pileus convex, acute (subumbonate), about 2.5 cm broad, white fleshed. Lamellae simple, unequal, thick, almost free, attenuate at both sides, straight on the back, brown, reddish brown, hardly broader than 2.5 mm. Stipe 4.5 mm thick and 4 cm long, floccose-pruinose at apex, in lower part striate with homogeneous veins. Odour and taste indistinct. Growing solitary in forest in the Harz, near Harzgerode, Falkenstein in September to October.

Commentary: Judging from the lectotype illustration, where both the pileus and stipe are shown with violaceous colours, this is certainly not a Hebeloma. Lange (1938a) suspected it might be Cortinarius pulchellus Lange. It might even possibly correspond to Inocybe lilacina (Peck) Kauffman.
