Full name: Hebeloma suaveolens Velen. (1920)
Published: Ceske Houby: 399 (1919) ["1920"]
Taxonomic status: We have not been able to unambiguously determine the current genus of this name.
Types: No material located in PRC. Described from Czech Republic, Ptociny forest near Mnichovice with Picea.

Original diagnosis: Pileo 3-5 cm diam., elasticiter carnoso, rotundato-convexo, margine anguste involuto et subtiliter albo-tomentoso, tum explanato et irregulariter lobato, subrubello-alutaceo, sicco, subtiliter tomentoso-squamuloso. Stipite pilei diam. vix longiori, 1-1,5 cm crasso, firme elastico, solido, basi adunco, sed non incrassato, in filamenta longa alba abeunti, longitudinaliter grosse striato-fibrilloso, sed haud lucido, albo, apice rubro-inhalato et sub lamellis abundanter albo-furfuraceo, squamuloso. Lamellis angustis, postice paulisper emarginatis, albis, dein sordide ochraceis, acie albis et denticulatis. Carne alba, odore dulci, penetranti amoeno. Sporis luteolo-subfuscis, ovato-ellipsoideis, 8 μm. Cystidiis numerosis, curvulato-filiformibus, obtusis. In strato conservato profundo aciculorum i piceto adulto una cum Psalliota arvensi in silva Potociny dicta prope Mnichovice augusto quotannis. Species Hebelomatibus certe ascribenda, sed ab omnibus descriptis longe diversa. Tricholomata fere in mentem revocat, sed sporas fuscas habet.

English translation: Pileus 3–5 cm broad, elastically fleshy, rounded-convex, with narrowly involute margin, delicately white-tomentose, then expanding and irregularly lobed, pale brown with reddish tinge, dry, subtly tomentose-squamulose. Stipe length hardly exceeding the diameter of pileus, 1–1.5 cm thick, firm, elastic, solid, curved at base, but not broadened, with long white fibrils disappearing (in the soil), coarsely striate-fibrillose, but not shiny, with reddish flush at apex, and between the lamellae densely white-furfuraceous, squamulose. Lamellae narrow, weakly emarginate, white then sordid ochraceous, with white, denticulate edge. Context white, with sweet, penetrating, pleasant odour. Spores yellowish brownish, ovate-ellipsoid, 8 μm. Cystidia abundant, curved-filiform, blunt. In mature Picea forest conservation area on very acid soil together with Psalliota arvensis (Agaricus arvensis) in the Ptociny forest near Mnichovice every year in August. It is a species that certainly belongs to Hebeloma, but greatly differing from all described species. Also reminding of Tricholoma, but having brown spores.

Commentary: The ‘original diagnosis’ above is the translation into Latin from the original Czech by Pilat, Opera Bot. Čechica 6: 138 (1948). Described with a penetrating sweet odour, a dry and finely tomentose-squamulose pileus and ovate-ellipsoid spores about 8 µm long. This does not agree with any known Hebeloma species, and we believe that this is not a Hebeloma.
