The brown-haired root root ( Xerula pudens , syn. Oudemansiella longipes ) is a fungus from the family of the bark sponge relatives (Physalacriaceae).
features
Macroscopic features
The dry, light beige to brownish hat is three to six centimeters wide and has a fine-velvety consistency. The stem is cinnamon brown and also velvety. The lamellae are whitish, with age also slightly yellowish or pink, quite thick and distant. They are bulged onto the stem and almost free. The spore powder is white.
Microscopic features
You can also recognize it by the roundish looking spores . They grow to be 8-10.5 × 5-6 micrometers in size. Thick-walled cystids , which are often covered with crystals, occur on the cutting edges and also on the surfaces of the lamellae .
Species delimitation
The black-haired root root ( Oudemansiella melanotricha ) differs from the brown-haired root root in its bristly hat and handle, the hair of which is often over a millimeter long. The velvet foot ruff ( Flammulina velutipes ) also has a certain similarity due to its similarly velvety stem.
taste
Sometimes bitter, mostly inedible.
Occurrence
It grows in the deciduous forest, rarely under oaks, especially on limestone soils. It fructifies from August to September. In Germany it grows from the Alps to the Baltic Sea, albeit with large distribution gaps.
Danger
According to the Red List of Endangered Large Mushrooms in Germany, this fungus is classified as endangered.
Distribution and ecology
It grows as a saprophyte in rotten, dead hardwood, preferably that of beech . It fructifies from June to October with rather solitary fruiting bodies on tree stumps. It occurs in Europe and America.
Systematics and taxonomy
It is assigned to the genus of the root carrots ( Xerula ) or, by some authors who do not recognize this genus, is incorporated into the slime carrots ( Oudemansiella ). The official first description goes back to Christian Hendrik Persoon , who described the species in a first supplement to his main work "Flora cantabrigiensis - exhibens plantas agro cantabrigiensi indigenas, secundum systema sexuale digestas." Singer described the species validly in 1951. The synonym Oudemansiella longipes is also widespread .
use
It is considered inedible.
