Features

Macroscopic characteristics

The fleshy hat is 5-12 cm broad, convex to spread out and often soon bent fluttery. Often, the hat is also hunched wide and the beveled edge abruptly. The surface appears mostly in rather gloomy dark olivgrauen to olive-brown colors. Sometimes a weak violet shimmer is visible. The hat skin is finely intergrown fibrous, greasy wet and dry almost shiny and removable.

The narrow, moderately removed lamella bulges are grown on a stick. You are already gloomy young sooty - olive to dark brown and russet aged up olivschwarz. Between the lamellae are numerous intermediate fins find. The blades are often somewhat lighter colored and finely notched, the spore powder is rust brown.

The solid stem is 3-8 cm long and 1-2 cm wide up. It is usually cylindrical, but may also have a clavate or thickened tapered base. The stem surface is pale brown or colored in different shades of the hat, the stem tip can sometimes have a purple sheen. The Cortina is olivbräunlich.

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

Microscopic characteristics

The short- ellipsoidal to rounded and warty spores are 7-8, sometimes up to 10 microns long and 5.5-6.5 microns wide. Cystidia are absent or inconspicuous basidiolenartig formed.

Artabgrenzung

The Bitter mucus head is quite variable, from him several variants are described. It can with the mild Olivgelben mucus head ( Cortinarius subtortus ) be confused, however thrives on acidic, boggy soils and a pleasant incense odor.

Ecology

The Bitter mucus head is found mainly in beech forests. More rarely he inhabits other deciduous forests. At times, the type are also found in coniferous forests on base-rich sites. In addition, they can also be found in parks, cemeteries, meadows and heaths. The fungus colonized this basic and neutral, rare acidic loam and sandy soils. It is encountered in the planar to eumontanen, especially in the submontane - montane zone.

It forms a mycorrhiza with deciduous and coniferous trees, especially with the red beech and spruce of Commons. The fruiting bodies appear only in a fairly short period from late summer until the middle of autumn.

Dissemination

The Bitter mucus head is common in North America (USA) and Europe. In West - Central and Southern Europe as well as in the southern Northern Europe it is widespread and scattered to make up places frequently. In addition, the species is scattered to rarely found in Eastern Europe, Norway and Finland. In Germany it is one especially in the south, in the southern Lower Saxony and Thuringia to the more common slime heads. Otherwise they will absent-minded until rare.

System

The Hutfärbung is highly variable, which is why several color variants are described. When var Infractus the surface is yellowish to yellow-brown or dark olivaceous more in var anfractus. The var obscurocyaneus has a very dark olive-brown to olivschwarzen hat on. When var olivellus he is olive-green. However, can emerge from a differently colored mycelium fruiting bodies.

Importance

The Bitter mucus head is not edible mushroom and may even slightly toxic.
