Full name: Inocybe velenovskyi Hruby (1930)
Published: Hedwigia 70 (3-4): 281 (1930)
Taxonomic status: Heterotypic synonym of H. mesophaeum
Notes: Nom. illegit. (Art. 53.1 - Melbourne).

Types: CZECH REPUBLIC: Moravia, Brno, Hadyberg, Loscher Wald, Monchsberg nera Bystré (approx. 49.6285°N, 16.3468°E, alt. approx. 600 m a.s.l.), Sep. 1927, J. Hruby (Lectotype. herbarium acc. no. BRNM 7034/39, HJB1000257). Lectotype designated by Kuyper, Persoonia Suppl. 3: (1986) page 238.

Original diagnosis: Ein kleines, sehr zierliches Pilzchen, das sich enge and I. caesariata Fries anschließt. Auch die var. cuchlensis Vel., C. H. S. 386 kann es unmöglich sein. Hut 1 bis 0.5 cm breit, zuerst ausgesprochen kegelig, Rand eingerollt, später breit abgeflacht, aber mit vorspringendem Höcker, feucht dunkelgraubraun, trocken verblassend, bald ganz verkahlend, nur der lange eingerollte Hutrand von den dicken, häutigen Cortina Resten behängt, trocken. Stiel sehr verlängert, bis 3 cm und darüber, 0.1-0.2 cm dick, oben Weiß, unten lichtbräunlich, mit seidig-wolliger, dicker Rinde, ziemlich gerade und gleich dick, oben verkahlend; Fußende meist mit kleinem Knöllchen. Lamellen dicht, sehr schmal und dünn, bald blassbräunlich, mit Weißer Schneide, angeheftet. Zystiden wie bei I. caesariata, abgegrenzt. Fleisch weißlich, geruchlos. Spores fast eiförmig, 7-8 μm. Brünn, Hadyberg; Löscher Wald.

English translation: A tiny, very graceful fungus, which comes close to I. caesariata of Fries. It cannot possibly be the var. cuchlensis of Velenovsky, C.H. page 386, either. Pileus 1 to 0.5 cm broad, distinctly conical at first with inrolled margin, later broadly expanded but with distinct umbo, when moist dark grey-brown, pallescent on drying, soon entirely glabrescent, only on the long inrolled margin covered with remnants of the thick, membranous cortina, dry. Stipe very elongate, up to 3 cm or more, 0.1–0.2 cm thick, white at apex, pale brown below, with silky-woolly, thick cortex, rather straight, glabrescent at apex; at base usually with a small bulb. Lamellae crowded, very narrow and thin, soon pale brown, with white edge, adnate. Cystidia as in I. caesariata, distinctly marked. Context white, without odour. Spores almost egg-shaped, 7–8 μm. Near Brünn (Brno), Hadyberg; Löscher Wald.

Commentary: As Kuyper (1986) was aware, and as confirmed by our morphological studies of the lectotype, this is: = Hebeloma mesophaeum (Pers.) Quél.

Full name: Inocybe velenovskyi f. incrassata Hruby (1930)
Published: Hedwigia 70 (3-4): 281 (1930)
Taxonomic status: Heterotypic synonym of H. mesophaeum
Types: CZECH REPUBLIC: Moravia, Brno, Monchsberg near Bystré (approx. 49.6285°N, 16.3468°E, alt. approx. 600 m a.s.l.), Aug. 1927, J. Hruby (Lectotype. herbarium acc. no. BRNM 7035/39, HJB14291). Lectotype designated by Beker et al., Hebeloma (Fr.) P. Kumm.: (2016) page 654 (MBT202541).

Original diagnosis: Hut bis 2 cm breit, mehr kastanienbraun, sonst wie vorige. Stiel viel dicker, am oberen stark verdickten Ende bis 0.6 cm, viel länger (bis 4.5 cm), ausgestopft; unter dem Hute bläulich angehaucht. Brünn: Mönchsberg bei Bystre, im tiefen Moosboden der Kiefern-Fichtenwaldes; August 1927.

English translation: Pileus up to 2 cm broad, rather chestnut brown, otherwise like the former (I. velenovskyi). Stipe much thicker, at upper part of the strongly enlarged base up to 0.6 cm, much longer (up to 4.5 cm), stuffed; with bluish sheen under the pileus. At Mönchsberg near Bystré, in the thick mossy undergrowth of the mixed pine-spruce forest, August 1927.

Commentary: Kuyper (1986) noted that this was a Hebeloma from the H. mesophaeum complex. We have studied the lectotype and this is: = Hebeloma mesophaeum (Pers.) Quél.
