Original diagnosis: Synonyme: Hebeloma crustuliniforme var. bulbiferum Favre non R. Maire, loc. cit. p. 488). - Pileo (2)-2.5-5.7 cm, primum e campanulato convexo, dein expanso, margine anguste involuta, dein magis minusve undata, e rufulo ochraceo, in ambitu pallidiore, cute viscidula, laeve atque paulum micacea, vetustate rugulosa. Stipite brevi, 2.5-5 x 0.5-0.7 cm, sursum cylindrato, deorsum manifeste bulbosa (usque ad 1 cm), plena, dein medullato, demum cavo, cortice firmo, albo vel albido, fere toto pruinoso. Carne crassiuscula, firmula, albida, paulum pallidissimo colore brunneolo in cortice stipitis tincta. Odore raphanoideo, sapore amarescente. Lamellis stipatis, triplici serie lamellularum, (2-)3-5 mm latis, rotundatis subliberis vel adnatis, pallide argilaceis, acie crenata ac guttulis plerumque limpidis, interdum lacteis. - Sporis late ovoideis-amygdaliformibus, (8.7-) 9-11.7 x 6-6.8 μm, 10-11.7 x 5.7-6.5-(8) μm (NH4OH), luteolis, sublaevibus vel subtiliter punctatis. Basidiis 20-32 x 8-10 μm. Pilis marginalibus longe clavatis, interdum inferne ampullaceis, 37-60-(80) x 5-6 μm x 6-9 m. Epicute gelata, pilis erectis (ixotrichodermate) longioribus x 3-4 μm, cylindratis, haud vel parum summis incrassatis, brevioribus (in strato inferiore) manifeste clavatis (5-7 μm), sparsis; subcute magis minusve manifeste specie pseudoparenchymatica. Fibulis praesentibus. - Sub Pinis pinastris, Quercibusque pedunculatis, locis graminosis, fossis luteis.

English translation: Pileus (2–)2.5–5.7 μm, at first campanulate convex then expanding, with narrowly involute margin, then strongly more or less undulating, first reddish then ochraceous, paler at margin, with slightly viscid cuticle, glabrous and weakly micaceous, with rugulose covering. Stipe short, 2.5–3.5 × 0.5–0.7 cm, cylindrical in upper part, manifestly bulbous at base (up to 1 cm), solid then medullate finally hollow, with firm cortex, white or whitish, almost entirely pruinose. Context rather thick and firm, white in cortex of stipe very pale brown. Odour aphanoid. Taste bitter. Lamellae crowded with three lengths of lamellulae (2–)3–5 mm broad, rounded almost free or adnate, pale clay-coloured, with crenulate edge and guttulate with a clear or sometimes milky liquid. Spores broadly ovoid-amygdaloid, (8.7–) 9–11.7 × 6–6.8 μm, 10–11.7 × 5.7–6.5(–8) μm in NH4OH, yellowish, almost smooth or subtly punctate. Basidia 20–32 × 8–10 μm. Marginal hairs long clavate, sometimes ampulliform below, 37–60 (–80) × 5–8 μm. Epicutis gelatinous, with long erect hairs (ixotrichoderm), 3–4 μm wide, cylindrical, not or at apex slightly enlarged, rarely widened in lower part and distinctly clavate (5–7 μm); subcutis somewhat more parenchymatical. Clamps present. With Pinus pinaster and Quercus pedunculata in grassy spots in muddy ditches.
