Full name: Hebeloma virgatum Velen. (1920)
Published: Ceske Houby: 398 (1919) ["1920"]
Taxonomic status: We have not been able to unambiguously determine the current genus of this name.
Types: No material found in PRC. Described from the Czech Republic, Aug. 1914.

Original diagnosis: Fere maius quam Hebeloma crustuliniforme. Pileo 5-8 cm diam., crasse carnoso, iuventute margine diu involuto, tum plane expanso, udo viscido, sicco levi, lucido, alutaceo-subfusco, sicut squamuloso, fibrillis fuscis innatis virgato et inter fibrillas rimoso-striato. Stipite pilei diam. aequilongo, ca 1 cm crasso, regulariter cylindraceo, firme elastico, levi, fibrilloso, apice cortina arachnoidea praedito (ut in Cortinariis), albido, sub lamellis granuloso. Lamellis confertis, tenuibus, decumbentibus, acie albis et paulisper dentatis, postice rotundato-liberis, albidis, tum ferrugineo-fuscis. Carne subroseo-alutacea, penetranter dulciter aromatica (ut Phlegmacia nonnula). Sporis ellipsoideo-amygdaliformibus, 6-7 μm. Cystidïis numerosissimis, longe curvulato filiformibus. In pinetis locis muscosis prope Habr (flora subalpine) augusto 1914. Sporae in cumulo rubro-fuscae. Fibrillas cortinae in stipites colorants. Quamquam species facile agnoscenda, attamen eam in literature reperire non potui.

English translation: About the same size as Hebeloma crustuliniforme. Pileus 5–8 cm diam., thick-fleshed, with long time staying involute margin when young, then expanding to plane, viscid when moist, smooth when dry, shiny, pale, somewhat sordid brown, also squamulose, virgate with dark brown fibrils, and between fibrils rimose-striate. Stipe with about the same length as pileus diameter, circa 1 cm thick, regular cylindrical, firm, elastic, smooth, fibrillose, at apex with arachnoid cortina (as in Cortinarius), white, granulose between lamellae. Lamellae crowded, thin, emarginate, with white, weakly denticulate edge, rounded free, white then dark sordid redbrown. Context pinkish-pale brown, with penetrating sweet aroma (rather like Phlegmacium). Spores ellipsoid-amygdaloid, 6–7 μm. Cystidia abundant, long, curved-filiform. In mossy places in pine forest near hornbeam (subalpine flora), August 1914. Spores in mass reddish brown, colouring the hyphae of the cortina. Although it is an easily recognisable species, it was not possible to find it in literature.

Commentary: The ‘original diagnosis’ above is the translation into Latin from the original Czech by Pilat, Opera Bot. Čechica 6: 137 (1948). The spore length given (6–7 µm long) does not match any known Hebeloma. Neither does the combination of a penetrating sweet odour and a veil. We therefore believe that this is not a Hebeloma species.
