Systematics
Subclass : Agaricomycetidae
Order : Agaricales
Family : Veil relatives (Cortinariaceae)
Genre : Veils ( Cortinarius )
Subgenus : Mucous feet ( Myxacium )
Type : Blue slimy foot
Scientific name
Cortinarius salor
Fr.

The blue mucous foot ( Cortinarius salor ) is a leaf fungus from the family of the veil relatives (Cortinariaceae). The medium-sized veil has a slimy hat and an equally slimy stem. Both hat and stem are deep purple in color when young. It is also characterized by its mild-tasting flesh, the relatively narrow, cylindrical and weakly belted handle and its almost spherical spores. The rare mycorrhizal fungus usually grows in deciduous forests on calcareous soils. The fruiting bodies appear predominantly from August to October. The veil is regarded by some authors as conditionally edible, but mostly described as inedible.

Macroscopic features

The hat is 4–9 (10) cm wide, hemispherical or bell-shaped when young, later arched, then spread out flat and often bluntly hunched. The surface is very slimy and has a striking blue-violet color when young. Later it fades from ocher yellow to ocher brown from the top.

The quite close standing lamellae are slightly bulged on the stem. They are initially violet-blue and later turn gray-brown to rust-brown due to the rust-brown spore powder.

The more or less cylindrical stem is 5–12 cm long and 0.5–1.5 cm wide. It is sticky-shiny or slimy (especially below the velum zone) and initially colored similar to the hat, but paler. Later it is more or less whitish. The velum is lilac-blue and later gray-olive yellow. The stem is often faintly girdled by the velum zone colored by the spore dust. The stem base is club-shaped and can be up to 3 cm thick.

The flesh is whitish, later cream-colored to gray-brownish and has a faint shade of blue. It is initially bluish in the tip of the stem. The smell and taste of the meat are inconspicuous.

Microscopic features

The almost spherical and warty spores measure 7–9 × 6–8 (8.5) µm.

Species delimitation

Characteristic features are the blue-violet hat and lamella color of young fruit bodies, the almost spherical spores and the mild-tasting meat. The saffron blue mucous foot ( C. croceocaeruleus ) can be quite similar, but it tastes bitter and has elliptical to almond-shaped spores.

distribution

European countries with evidence of finding of the blue slime foot.
Legend:
  • Countries with found reports
  • Countries without evidence
  • no data
  • non-European countries
  • The fungus is found in North America (USA), Asia (Japan, North Korea, South Korea) and Europe. It is widespread in almost all of Europe, only from the Balkan Peninsula there is no evidence so far. Overall, the mucous foot is quite rare. In the south it is distributed from Spain to Italy to the Ukraine. The veil is found all over Fennoscandinavia and has also been found in Iceland. In the north, its distribution area extends beyond the 65th parallel, in Sweden occasionally even up to the 67th parallel. The mucous foot is rare in Great Britain and has only been found sporadically in England. He is also missing in the Netherlands. In the Alpine countries of Switzerland, Liechtenstein and Austria it can be found quite frequently to frequently. In Germany, it occurs mainly in Bavaria and Baden-Württemberg. In the northern and eastern federal states it is rare or completely absent. The highest site in Switzerland is at 2050 m above sea level, in Austria it has still been proven at over 1900 m above sea level.

    ecology

    The fruit bodies appear gregarious from August to October, occasionally sooner or later. The mucous foot grows in both deciduous and mixed forests. It is particularly common in grassy or herbaceous areas under red beeches and spruces. But it also occurs in oak, birch and fir trees. It prefers limestone soils (23% of the species recorded in Austria grew on limestone soils, almost 15% on silicate soils). In Switzerland, the veil is particularly widespread in the Jura and the northern flank of the Alps (both limestone areas).

    Systematics

    The blue mucous foot was first described in 1838 by Elias M. Fries in his work Epicrisis systematis mycologici as Cortinarius salor . The mucous foot is in the subgenus Myxacium and there in the Delibati section . The representatives of the section are characterized by a smooth, slimy to sticky stem below the velum zone, almost spherical to broadly oval spores and a mild taste.

    meaning

    Despite its mild taste, the mucous foot is considered inedible.
