features

Macroscopic features

The fleshy hat is 5–12 cm wide, arched to spread out and often quickly bent to flutter. Often the hat is also hunched wide and the edge beveled abruptly. The surface usually appears in rather gloomy dark olive-gray to olive-brown colors. Occasionally a faint purple sheen can also be seen. The hat skin is finely ingrown, fibrous, moist, greasy and dry, almost shiny and removable.

The narrow, moderately distant lamellae are bulged on the stem. They are dark sooty-olive to dark brown when young and rust-brown to olive-black when they are old. There are numerous intermediate lamellae between the lamellae. The edges are often a little lighter in color and finely jagged, the spore powder is rust-brown.

The stiff stem is 3–8 cm long and 1–2 cm wide. It is usually cylindrical, but can also have a thickened or pointed base. The stem surface is pale brown or colored in the different tones of the hat, the stem tip can sometimes have a purple sheen. The Cortina is olive-brown.

The full, firm meat is up to 2 cm thick in the hat. It is whitish to gray and sometimes has a bluish tinge. The meat tastes very bitter and has a rather inconspicuous odor.

Microscopic features

The short ellipsoidal to roundish and warty spores are 7–8, sometimes up to 10 µm long and 5.5–6.5 µm wide. There are no cystids or they are inconspicuously shaped like a basidiolus.

Species delimitation

The bitter mucous head is quite variable, different variants of it have been described. It can be confused with the mild olive yellow mucous head ( Cortinarius subtortus ), which, however, thrives on acidic, boggy soils and has a pleasant incense smell .

ecology

The bitter mucous head is mainly found in beech forests. It inhabits other deciduous forests less often. Sometimes the species can also be found in coniferous forests in areas rich in bases. It can also be found in parks, cemeteries, on meadows and heaths. The fungus colonizes basic and neutral, less often acidic, loamy and sandy soils. It is found in the planar to eumontane, especially in the submontane-montane altitude range .

It forms a mycorrhiza with deciduous and coniferous trees, especially with the common beech and the common spruce . The fruiting bodies appear only in a very short period from late summer to mid-autumn.

distribution

The bitter mucous head is common in North America (USA) and Europe. In western, central and southern Europe as well as in southern northern Europe it is widespread and scattered or found frequently. In addition, the species is found absent-mindedly or rarely in Eastern Europe, Norway and Finland. In Germany, it is one of the more common slime heads , especially in the south, in southern Lower Saxony and Thuringia . Otherwise it occurs scattered or rarely.

Systematics

The color of the hat is very variable, which is why several color variants are described. When var. Infractus the surface is yellowish more dark olive in the var. To yellow-brown or anfractus . The var. Obscurocyaneus has a very dark olive-brown to olive-black cap. The var. Olivellus is colored olive green. However, different colored fruit bodies can emerge from a mycelium.

meaning

The bitter mucous head is not an edible mushroom and may even be slightly poisonous.
