Hebeloma versipelle - A non-current Hebeloma species

According to our data Hebeloma versipelle is not the name of a current valid species of Hebeloma. Our database has records for the following similar names

Full name: Hebeloma versipelle (Fr.) Gillet [as “versipellis”] (1876)

Taxonomic status: This is a Hebeloma but we have not been able to unambiguously determine the species.
Basionym: Agaricus versipellis Fr. (1838) [“1836-1838”]

Types: Not designated. Described from Sweden.

Homotypic synonyms: Hebelomatis versipelle (Fr.) Locq. (1979) [“1977”]; Inocybe versipellis (Fr.) P. Karst. [as “versipellis”] (1879); Hylophila versipellis (Fr.) Quél. (1886)

Original diagnosis: A. versipellis, pileo carnoso convexo plano glutine tenaci viscoso discoideo, versus ambitum adglutinato-sericeo, dein glabro, stipite fistuloso tenaci albosericeo apiceque pruinoso, lamellae rotundatis confertis latis (3-5 lin.), ex albo-carneo argillaceis.

Sericeo e velo fibrilloso evanido stipes fibrillosi-striatus, intus fuscescens. Pileus tenuis, subpunctatus, regularis, crustallinus: demum repandus, siccus, alutaceus, opacus. Odor debilis, non ingratus.

English translation: Agaricus versipellis, pileus fleshy, plano-convex, viscid with sticky mucus orbicular, shiny, not viscid at margin, then glabrous, stipe hollow, tough, white-sericeous with pruinose apex, lamellae rounded attached, crowded, broad, (7–11 mm), white-incarnate then pale brown. Agaricus lubricus Aman., A. thelephorus Secr. n. 576. Clus. pern. g. XII. Sp. 1! Sterb. t. 20. B. Grassy places, along roads, spring, subcaespitose. Surprisingly changing with age and weather. Stipe silky from fibrillose, evanescent veil, fibrillose-striate, turning brown inside, pileus thin, ornamented with fine punctae [minute squamules], regular, bread crust-coloured, then irregularly wavy, dry, pale brown, opaque. Odour weak, not unpleasant.

Commentary: Judging from the protologue this is most likely Hebeloma mesophaeum, but the possibility that it may be H. dunense cannot be excluded. Hence we cannot, unambiguously, determine this taxon.

Original diagnosis: Chapeau 1,5-2,5 cm, convexe, à marge enroulée, un peu grivé mais sans voile évident, peu visqueux, brun-beige à roussâtre au centre, un peu plus beige ocracé vers la marge, sans cocarde bien délimitée. Lames banales, adnées, non pleurantes. Stipe 2-3 x 0,5-0,6 cm à cortine étalée sur fond brunâtre, un peu brunissant. Chair crème à ochracé roussâtre. Odeur nulle; saveur subdouce. Spores 9-10 (12) x 6-7 μm, subamygdaliformes ou elliptiques à sommet ogival, finement pointillées, brun-jaune sous micro. Cheilocystides 50-60 x 6-10 x 5-6 μm, lagéniformes, à col cylindrique et sommet parfois un peu clavé. Epicutis à hyphes grêles 3-5 μm, +/- gélifiées. Hypoderme subcelluleus. Mouillettes, mousses diverses.

English translation: Pileus 1.5–2.5 cm, convex, involute margin, slightly pruinose but no veil evident, slightly viscous, beige-brown to reddish in the centre, more beige to ochraceous towards the margin, without well delimited zones. Lamellae adnate, without tears. Stipe 2–3 × 0.5–0.6 cm with spread brown cortina, slightly darkening (browning) in colour. Flesh cream to reddish ochraceous. No odour; taste mild. Spores 9–10 (12) × 6–7 μm, subamygdaloid or elliptic with pointed apex, finely punctate, brown-yellow under the microscope. Cheilocystidia 50–60 × 6–10 × 5–6 μm, lageniform with a cylindrical neck and apex sometimes slightly clavate. Epicutis with slender hyphae 3–5 μm, +/- gelatinous. Trama below cutis subcellulose. Damp places with various mosses.

Commentary: We guess from the author’s description of this taxon that the author had Hebeloma dunense in mind. While his description could also fit H. marginatulum, he keys this taxon out separately within his key. Thus: = Hebeloma dunense L. Corb. & R. Heim.

FRANCE: in woodland under Pinus sp. and Quercus sp., , C.H. Persoon (Neotype. herbarium acc. no. L910.255-852, L L0115239, HJB1000296). Neotype designated by Singer, Persoonia 2 (1): (1961) page 33.

The neotype was designated as a “lectotype” by Singer (Persoonia 2: 33, 1961) but there are no indications as to the date of collection (or even location) and therefore it is not certain that it represents original material studied before the publication of the name. However Singer’s designation can be considered a neotypification under Art. 9.9. This material is in accordance with the protologue and as there are no other candidate original materials and no cited illustrations we accept this as a neotype.
