First described as Hypophyllum sinapizans by Jean-Jacques Paulet in 1793,[3] it was transferred to the genus Hebeloma by Claude Casimir Gillet in 1878.[4] It is commonly known as the "rough-stalked Hebeloma".[5]
The fruit body has a cap that is initially convex before flattening out in age, reaching a diameter of 4–15.5 centimetres (1+1⁄2–6 inches). The cap may have a shallow umbo. The cap surface ranges from moist to sticky, and it is smooth with a margin that is first curled inward and expanding to become curled upward in maturity; the cap color is whitish-tan to cinnamon-tan, sometimes with pinkish- or reddish-brown tints. The flesh is whitish, thick, and has a radish-like odor and taste. Gills have an adnate attachment to the stipe, and they have a notch just before the point of attachment; the gill edges have tiny fringes or serrations. They are first whitish before turning to yellowish-brown to pale brown after the spores mature.
The stipe measures 2–5 cm (1–2 in) long by 1.3–2.5 cm (1⁄2–1 in) thick, and is roughly equal in width throughout its length.[5]
Fruit bodies produce a pale brown spore print. Spores are elliptical with a rough surface texture, and measure 10–14 by 6–8 μm.[5]
It is similar to the more common H. crustuliniforme, a smaller relative that is also poisonous.
As of December 2022, the species has been found in 20 countries across Europe as well as in Asiatic Turkey and Lebanon.[6]
The fungus fruits on the ground in groups or fairy rings in deciduous and coniferous forests.[5]
H. sinapizans mushrooms are poisonous.[5]
