The thin-fleshed hat reaches 3 to 8 centimeters in diameter, is bell-shaped when young and soon becomes flat later, has a sometimes pronounced hump and is radially corrugated and dented. The surface is dry, matt and very light, moist, slimy and shiny and colored light yellowish brown to ocher or hazel brown. The lamellae are white (lich) and thick, stand away and are straight to bulged on the stem. The cutting edges are often darker in color. The tough stalk is 8 to 20 centimeters long, 3 to 10 millimeters thick, longitudinally fibrous, full-fleshed, later hollow, often twisted and roots deep in the substrate. Its surface is bare, above white, deeper and increasingly (gray) brownish and the rooting base is white again. The white meat smells insignificant (without odor or slightly fruity) and tastes mild to bitter. The mushroom has no velum . The spore powder is white.
The spores measure 12 to 18.5 by 9 to 12 micrometers, are oval shaped, and amyloid . He has centered swollen pleuro Zystiden with broad rounded ends. In hyphae are buckles connections available. They show no color reaction ( inamyloid ) with iodine chemicals .
Species delimitation
The pit, smooth hat, slender shape and rooting stem are typical and make the common species quite distinctive.
The broad-leaved turnip ( Megacollybia platyphylla ) has a much thicker stem that does not have deep roots and tough white, 1 to 2 millimeter thick rhizomorphs hang on the stem base .
The beech forest water foot ( Hydropus subalpinus ) is similar . It usually stays smaller, does not take root and has a thin, glassy, translucent stem that exudes a watery sap when it breaks through.
The rare brown-haired root root ( Xerula pudens ) and the equally rare black-haired root root ( Oudemansiella melanotricha ) differ in their velvety surface with brown or black hair on the hat and handle.
Distribution and ecology
The species is common and grows as a parasite and saprophyte on rotten, dead hardwood , preferably that of European beech , often apparently on the ground, with the rooting stalk connected to the tree roots of the host trees . Spruce is also very rarely colonized. It fructifies from June to October, individually or in small groups. It occurs in Europe and America.
Systematics and taxonomy
The official first description goes on Richard Relhan back of the way in a 1786 published the first supplementary part to his major work - as "Flora cantabrigiensis exhibens plantas agro cantabrigiensi indigenas, secundum systema sexuale digestas." Agaricus radicatus described.
Since then, the species has been placed in different genera, including the slime rot ( Oudemansiella ) and the root rot ( Xerula ). In 2010 the genus Hymenipellis was established, which is characterized by a hat skin made up of club-like cells, which are also found as basidiols in the hymenium . In connection with the Latin pellis (= fur, fur), the scientific generic name is founded . The Grubige Wurzelrübling is the only European species of the genus.
use
The species is edible and used as an edible mushroom , although it is viewed as inferior and the stems are considered inedible due to their toughness.
