Macroscopic features

The fruit bodies are covered by the remains of a slimy overall covering ( Velum universale ). In young fruit bodies there is also a hair veil-like partial covering ( cortina ) between the edge of the hat and the stem. The thick-fleshed hat measures 4–10 cm in diameter. It is arched to spread out and sometimes somewhat indented with a long, inflected edge. The surface is smooth, very slimy, shiny and colored with yellowish or orange to red-brown tones with a darker center. The lamellas are narrow and bulged on the handle. They are ocher-colored in young mushrooms and later turn cinnamon-brown or rust-colored due to the ripening spore powder. The stem is 5–15 cm long, cylindrical or tapering upwards and sometimes somewhat thickened at the base. Its surface is smooth or slightly scaly under the cortina, covered with slimy, white and has a brown belt zone, but no ring. The meat ( trama ) is whitish or brownish in the stem and has neither a special taste nor a specific smell.

Microscopic features

The spores measure 12–17.5 × 5.5–7.5 micrometers, are elongated lemon-shaped, have a rough or warty surface ( ornament ) and are rust-brown in color. Four of them grow on the spore stands ( basidia ). On the fins cut any sterile elements are (Cheilo Zystiden before). The transverse walls ( septa ) of the fungal threads ( hyphae ) have buckles .

Species delimitation

It is considered to be easily distinguishable. The bright yellow club foot ( Cortinarius splendens ) is a poisonous possibility of confusion . The bitterest slime foot ( Cortinarius vibratilis ) is more similar , which can spoil a meal individually. The honey mucous foot ( Cortinarius stillatitus ) can also be used for confusion.

Ecology and phenology

The heather mucous foot grows in acid, sandy soil in a mycorrhizal symbiosis with birches or conifers. The fruiting bodies appear from August to October.

distribution

It is common in Europe and only occurs occasionally.

meaning

The heather slime foot is edible and used as an edible mushroom , but it can also accumulate mercury .

Systematics and taxonomy

It is sorted into the Myxacium section in the sub-genus of the mucous feet ( Myxacium ) of the genus of the veils ( Cortinarius ). The official first description comes from a work by Jean Baptiste François Bulliard published in 1792 , where he called it Agaricus mucosus . The type epithet is a Latin masculine adjective that means "slimy".
