Deadly Webcap

Cortinarius orellanus

poisonous
  • Habitat: deciduous
  • Fruiting season: June – October
  • Cap: hemispherical umbonate scaly wrinkled velvety wavy
  • Stem: cylindrical tapering
  • Fertile layer: curved adnate sparse thick convex

Description

Cap: Convex or flat, thin-fleshed, 3-7 cm in diameter. Color brown, yellowish-brown, reddish-brown, orange-brown, covered with fine, fibrous scales, later bare. Not sticky. Remnants of the cobweb-like veil are sometimes visible on the cap margin.

Gills: Initially pale brownish-yellow, finally rust-colored. Spores yellow, almond-shaped, granular.

Stem: Slender, thin, rigid, straight, 3-8 cm long, 3-10 mm thick. Yellow-, brownish-yellow, rust-brownish, lighter in color than the cap.

Flesh: Firm, tough, leathery, brownish or rust-brownish. Smell and taste:

Spore: Rusty, reddish-brown, 9-12.5 x 6.5-8.5μm. spherical, rough surface.

Occurrence: On forest soils, primarily in mountain coniferous forests, in summer and autumn, abundant in many places. Here, it has only appeared in certain locations.

Edibility: Poisonous. Prolonged, continuous consumption causes severe, possibly fatal poisoning, not classifiable into the usual poisoning types. Similar toxins have been detected in closely related species in northern countries.

Confusion: Does not resemble our edible mushrooms. Its darker color and habitat distinguish it well from the fairy ring champignon. Many other webcaps and some mock mushrooms resemble it, but none of them are edible.

Note: The Latin name Cortinarius refers to the partial veil that protects the gills on the young mushroom; cortina means curtain. In most species belonging to the Cortinarius genus, the partial veil connects the stem to the cap margin in the form of fine radial threads, unlike other membranous partial veils.

Species description: The great Swedish mycologist Elias Magnus Fries described and named the species Cortinarius orellanus in 1838.
