Hebeloma sinapizans, commonly known as the scaly-stalked heboloma,[2] rough-stalked hebeloma or the bitter poisonpie, is a species of mushroom in the family Hymenogastraceae. It has a strong radish-like smell and a prominent bulbous stem base. H. sinapizans is found in Europe and North America and is poisonous.
Taxonomy
[edit]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]
Description
[edit]The fruit body has a cap that is initially convex before flattening out in age, reaching a diameter of 4–16 centimetres (1+1⁄2–6+1⁄2 inches).[2] The cap may have a shallow umbo. The cap surface is smooth, moist to sticky, and first with an inrolled margin then becoming uplifted. It is tannish, sometimes with pinkish grayish tints.[2] The gills have an adnate attachment to the stipe and have a notch just before the point of attachment; the gill edges have tiny fringes or serrations.[2] They are first whitish before turning pale brown in maturity.[2] The spore print is pale brown.[2]
The stipe measures 2–13 cm (1–5 in) long and 1–3 cm (1–3 cm) thick; it is roughly equal in width except for a swollen base.[2][5] The flesh is whitish, thick, and has a radish-like odor[2] and taste. The spores are elliptical with a rough surface texture and measure 10–14 by 6–8 μm.[5]
Similar species
[edit]It is similar to the more common H. crustuliniforme, a smaller relative[2] that is also poisonous.
Distribution and habitat
[edit]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]
Toxicity
[edit]H. sinapizans mushrooms are poisonous,[5] causing gastrointestinal upset.[2]
