The Rotscheibige deafblings ( Russula rhodella ) is a mushroom from the family of the deafblings relatives . The small, mild-tasting blubber has a copper-red hat and ocher-colored lamellae. In Germany, the very rare fungus can only be found in a few locations in deciduous forests.
features
Macroscopic features
The hat is 2–4 (–5) cm wide and almost fleshy, the edge is slightly grooved, at least in old age. The hat is colored copper-red and has about the same color as the brick-red blubber , or it is a little paler or tends more towards purple. The center is often more yellow-orange, the edge more pink to flesh-colored. The skin of the hat is young or, when damp, a bit greasy, shiny, dry, but almost matt, sometimes almost velvety and even tears a little at the end. The hat skin can be peeled off almost entirely.
The lamellas are very fragile and are quite close together. They are quite broad, blunt and free on the stem. When young they are initially whitish, then pale ocher when ripe. The spore powder is also pale ocher ( IIIa-b after Romagnesi ).
The stem is 3–6 cm long and 0.5–1 cm wide. It is usually white and only in rare cases has a washed-out pink color. At the base it often becomes rust-brown spotted.
The flesh is white and hardly yellowing; under the hat skin it is pink. It has no particular smell and tastes mild. With guaiac it reacts quickly and intensely.
Microscopic features
The spores are (6) 7–8.5 (–9) µm long and 5–6 (–7) µm wide and have fairly isolated spiny warts that can also be partially lined up. The cystids are almost 40–55 µm long and 8–12 µm wide and often appendiculate . The 2–4 (5) µm wide hyphal end cells of the cap skin are more or less frayed or almost bulbous or teat-shaped. Sometimes they are also twisted or contracted. The Pileocystiden are 5–8 µm wide and several times septate.
Ecology and diffusion
Like all Bluebirds, the Rotscheibige Bluebird is a mycorrhizal fungus that can enter into a symbiotic relationship with various deciduous trees. Mostly red beeches and oaks come into question. In France, chestnuts can also serve as hosts. Therefore, the fungus can be found in red beech and oak-hornbeam forests on mostly acidic soils. The species occurs only in Europe. It was made in France, the Netherlands, Belgium,
and Germany, but it is very rare everywhere.
Systematics
Inquiry systematics
The Rotscheibige Täubling is the type species of the subsection Rhodellinae , a subsection of the Tenellae section . The representatives of the subsection are mostly smaller blanks with more or less red or orange colored hats. The meat and the handle are only slightly yellow. The mild-tasting deafblings have no or only a very weak odor. The spore powder is cream to ocher yellow.
Subspecies and varieties
- Russula rhodella var. Heterosperma Sarnari (1993)
- Practically the same as the type species. The variety is characterized by the variable hat color. The hat can be cream-colored to flesh-colored, yellow-brown to copper-red, red-brown or bright red to purple-red. The lamellas have a slightly pungent taste and the meat only browns slightly. The spore powder is ocher in color. One can find the deaf under the beech.
meaning
Like all mild-tasting deafblings, the red-disc deafblings are also considered edible.
