Cortinarius

Bitter mucus head ( Cortinarius Infractus )

The veil Linge ( Cortinarius ) are a very large genus in the family of the veil Ling relatives. Under mycologists, the term Corti arias is customary to refer to this genus. The scientific name derives from the Latin Cortinarius Cortina which translates to " veil " is. The latter is a very fine, spidery fibers formed from velum between brim and handle, so the genus is also called Haarschleierlinge. The Cortina is a characteristic feature, but also occurs in some other genera.

In Central Europe, there are about 500 species, more than 2,000 species are distinguished worldwide.

Features

Macroscopic characteristics

The fruiting bodies are very variable in shape and size. They are thin - to thick-fleshed and very small (under 1 cm) to very large (over 20 cm). The hat is either curved, shaped bell-shaped or conical. It almost all occur in the fungi represented hat colors. The hat skin is membranous, slimy, fibrous felt-like, scaly or bald. From stem to the brim spans a spider-web veil, which remains after the Aufschirmen the hat mostly as fibrous residue at the stem. The stem has a very delicate and thin to very thick mold is slimy or dry, has Velumreste on or not, and is bare to fibrous structures. The meat is mild, bitter or sharp. The slats are usually bulged, but also broadly grown up arching on a stick. The color is rusty brown in mature specimens through the spore powder, in immature mushrooms the spectrum of almost whitish extends over vividly colored to dark - rust-brown or purple.

Microscopic characteristics

The rounded, elliptical, fusiform to almond or lemon-shaped and different sized spores always have a rust-brown color. They are warty ornamentation and rarely almost smooth. To determine also the presence of cystidia and their shape and size is critical.

Ecology and phenology

Veil compacts are invariably mycorrhizal fungi. They grow in the woods or under trees and fruiting bodies on the ground. The majority of species appear from late summer to late autumn.

Importance

According to the Swiss Ordinance on mushrooms the Barn Owl (C. praestans ) is the only marketable edible mushroom of the genus Cortinarius. However, there are also some species other than edible. Since the determination - especially for laymen - is very difficult in this species-rich genus, veils articles can generally not be recommended for consumption.

In addition to numerous non-edible and poisonous species, there are also very dangerous poison mushrooms: The Orangefuchsige Raukopf (C. orellanus ) and the Spitzgebuckelte Raukopf (C. rubellus, syn C. speciosissimus. ) Cause the Orellanus syndrome. The Harnkanäle the kidneys are destroyed, resulting in untreated organ failure. The Beautiful Yellow clubfoot (C. splendens) contains another, as yet unknown, strong kidney poison.

System

The genus includes the veil compacts in central Europe several hundred species - depending on the author - 6-9 subgenera. Many species can only be determined by specialists with the aid of microscopic features and chemical color reactions. The division of the following sub- classes is largely to Bon (1988):

• Veil compacts in the narrower sense ( Cortinarius )
• Skin heads ( Dermocybe )
• Rauköpfe ( Leprocybe )
• Mucus feet ( Myxacium )
• Mucus heads ( Phlegmacium ), including clubfeet ( Bulbopodium )
• Dick feet ( Sericeocybe )
• Belt feet ( Telamonia ), including water heads ( Hydrocybe )
