Subgenus : Mucous feet ( Myxacium )
Type : Adder-stalked mucous foot
Scientific name

JE long

The inedible adder-stalked mucous foot ( Cortinarius trivialis ) is a type of fungus from the family of veil relatives (Cortinariaceae). It has a yellow to olive-brown and often very slimy hat and an equally slimy and conspicuously brown-rattled stem. Like all veils, it is a mycorrhizal fungus whose gregarious fruiting bodies can be found in deciduous forests from July to October.

features

Macroscopic features

The hat is 4–10 (12) cm wide, hemispherical when young, then arched to spread out and often bluntly hunched. The shiny and usually very slimy surface is colored yellow-brown to red-brown or olive-yellow to ocher-yellow, the middle is usually a little darker. In rainy weather, the mucus layer is thickly swollen and dripping down from the edge of the hat. Young fruiting bodies have a long rolled up or inwardly curved hat rim that always remains unrubbed.

The lamellas, which are at least initially crowded, are bulged on the stem and often mixed with intermediate lamellae. Young they are pale and have a light purple tint, later they are colored cinnamon to rust brown by the rust-brown spore powder.

The stiff and also very slimy stem is 5–12 cm long and 1–2 cm wide and often slightly spindle-shaped at the base of the stem. The tip of the stem is whitish, with silky, light, later brownish remains of veil, underneath the stem is yellowish-olive to brownish girdled or latticed.

The firm flesh is pale yellow, often a little bluish at the tip of the stem and brownish at the base. It has no particular smell and tastes bland to bitter.

Microscopic features

The slender, almond-shaped, finely warty spores are 10–15 µm long and 7–8 µm wide; there are no cheilocystids .

Species delimitation

The very changeable adder-stalked mucous foot is primarily characterized by its brownish stalk, which is conspicuously lumped by the mucus. Older specimens of the blue-stemmed mucous foot ( Cortinarius collinitus ) can sometimes look quite similar.

ecology

Like all veils, the adder-stalked mucous foot is a mycorrhizal fungus that is mainly found in deciduous trees. Its most important hosts are beech, birch, oak, quivering poplar and willow. The fruiting bodies appear mostly gregarious from July to October in deciduous forests. It particularly likes to grow on loamy or calcareous soils. The species is very widespread and quite common in the mountainous regions, but is probably less common in the lowlands.

distribution

European countries with evidence of finding of the Natternstielign Schleimfußs.
Legend:
green = countries with found reports
cream white = countries without evidence
light gray = no data
dark gray = non-European countries.

The fungus is found in North America (Canada, USA), Asia (Japan, Mongolia) and Europe. You can find the widespread and quite common species almost everywhere in Europe. In Norway, its distribution area extends north to the 70th parallel.

meaning

The adder-stalked mucous foot is not an edible mushroom.
