Description

Cap: 5-10 cm in diameter; convex when young, then flattening, but bluntly umbonate in the center; its whitish surface is covered with yellowish, radial fibers and more or less erect, rust-brown scales from the veil.

Gills: Curved before the stem, then small tooth-adnate; whitish. Has densely arranged gills.

Stem: 4-8 cm long, 1-3 cm thick; cylindrical; often clustered; whitish base with yellowish, fibrous-scaly; its base is turnip-like thickened, ending in a whitish bulb, whose rim is decorated with yellowish-brown, erect scales.

Flesh: Thick; whitish; smell and taste not characteristic when young. With age, reminiscent of rotting fish, sweetish taste.

Spore: White; 5.5-6 x 4-4.5 µm, elliptical, transparent.

Occurrence: From June to October; parasitic on the ragged amanita growing in calcareous deciduous forests, but it only produces fruiting bodies very rarely, mainly in rainy and warm weather. A protected mushroom species in Hungary.

Edibility: Unknown due to its rarity. The mushroom is protected.

Confusion: The similar, two edible species, the acacia parasol and the scaly knight, have lemon-yellowish warts on their fruiting bodies, and their stem base is not volva-like.

Note: It probably follows the distribution of the ragged amanita, so it occurs in deciduous forests on calcareous soils. It only produces fruiting bodies in rainy, warm weather. The reason for its endangerment both nationally and internationally is that the weather and other conditions necessary for its fruiting body production are rarely given both in Europe and in Hungary.

Species description: In 1946, Emil J. Imbach described it scientifically. The genus includes 10 mushrooms, and the genus was created by Imbach.
