The yellow-pored blubber ( Russula flavispora ) is a fungus from the family of the blubber relatives . The rare deafblings looks very similar to the common white deafblings, but has yellow spore powder.
features
Macroscopic features
The hat is 6–10 cm wide and in young fruiting bodies initially arched, but later broadly depressed in the middle and deepened in a funnel-shaped manner with age. The brim of the hat is quite thin and rolled up at first. The hat skin is smooth and dry and shiny at first. It has grown and can only be removed very little or not at all. The hat is initially whitish in color, but becomes dirty brownish in the middle and is finally colored ocher-brown to pale milk coffee-colored. The center is darker than the paler edge.
The narrow, about 4–6 mm high lamellae are almost crowded and are quite creamy-yellow to cream-ocher in color. At the base they can have a more or less clear bluish tinge , as is the case with Russula chloroides var. Blumiana . They are heavily mixed with lamellets , but not cross-veined and run down the stem. The spore powder is pale yellow ( IVa-b after Romagnesi ).
The smooth or wrinkled (especially at the tip) stem is quite short, up to 3 cm long and up to 1.5 cm thick. At first it is whitish and full, then a little straw-yellow or brownish in color and pithy.
The white flesh is firm, thick and its smell is reminiscent of the scratchy comb-deaf or the common white-deaf, almost disgusting to slightly fruity but quite pleasant. The taste is sharp, burning sharp in the lamellae. With iron sulphate, the meat turns cloudy pink, the guaiac reaction is positive.
Microscopic features
The thorny spores are 7–9 µm long and 6–7 µm wide. The 0.7 to 1 µm high thorns are isolated or are rarely slightly burred or connected by fine lines, but never networked. The basidia are 47–60 µm long and 10–11.5 µm wide. The hillock is slightly amyloid . The cystids are up to 120 µm long and 10 µm wide. They are cylindrical and often appendiculated ; with sulfovanillin they can only be stained slightly and often only partially.
The cap skin has 2 (3) µm wide, very slender hyphae end cells and 3–5.7 µm wide pileocystids , which can be easily stained with sulfovanillin.
Ecology and diffusion
Like all Bluebells, the yellow-spore Bluebird is a mycorrhizal fungus that can enter into a symbiotic partnership with various deciduous trees. He probably prefers oaks , but red beeches and linden trees are also possible hosts. It can be found in beech but also in other deciduous forests, often on the edge of paths containing silicate.
It is a purely European species with primarily Mediterranean - Atlantic distribution. So far the species has been detected in France, Italy, Germany, Slovenia and Croatia. There has been no reliable proof from Austria since 1988.
Systematics
Inquiry systematics
The yellow-pored pigeon is placed by Bon in the Pallidosporinae subsection , which in turn is in the Plorantes section. The representatives of the subsection are dairy-like pigeons, which have more or less yellowish lamellae. The spore powder is also dark cream-colored to yellowish. The yellow-pored Täubling is closely related to the yellow-leaved Täubling .
meaning
Due to its sharp taste, the deafbling is considered inedible.
