The pale yellow deafblings ( Russula raoultii ) is a fungus from the family of the deafblings relatives . It is a small, rare blubber with a pale yellow hat and a very sharp taste.
features
Macroscopic features
The hat is 2–5 cm wide. The hat disc is more or less lemon yellow, the edge whitish, but the colors soon fade. The hat skin is smooth and can be peeled off. The lamellas are white and have a slightly cream-colored reflection. When young, they are slightly crowded, later more or less distant. The spore powder is white.
The stem is 2–4 cm long and 0.5–1 cm wide. It is white, often clubbed, easily compressible and quickly becomes hollow. Sometimes it is also a little gray. The flesh is white and fragile. It doesn't change with injury or with age. The taste is pretty sharp. The Täubling smells like the cherry red Spei-Täubling .
Microscopic features
The spores are oval, almost 8 µm long and 6 µm wide. They are covered with fine, pointed warts up to 0.75 µm high. The warts are more or less networked. Usually, however, an almost complete network is formed.
The basidia are 30–40 (55) µm long and 8–11 µm wide and have four sterigms. The pleurocystids are 50–85 µm long and 7–13 wide, are thin-walled and very common. They can be colored with sulfovanillin.
The Pileocystiden are about 5 - 7 µm wide, club-shaped and rounded at the tip. They are mostly simply septate, but sometimes also unseptate. They can also be colored with sulfovanillin. The hyphae end cells in the cap skin are narrowed, they contain vacuole but no membrane pigments. Filamentous hyphae or primordial hyphae do not occur in the cap skin.
ecology
The bass yellow pigeon, like all pigeons, is a mycorrhizal fungus that mainly forms a symbiosis with beech trees. Spruce and other deciduous trees can also serve as hosts.
The Täubling is found preferentially in beech forests such as grove beech forests and bedstraw beech forests , but also in spruce and fir forests. The Täubling occurs preferentially on fresh to moist, base and nutrient poor, acidic, sandy to loamy soils.
The fruiting bodies appear from July to early November. The fungus can be found from the higher hills to the middle mountains.
distribution
The pale yellow Täubling is a western Mediterranean, sub-oceanic species. The Täubling is found in North Africa (Morocco), North and Central America (USA, Costa Rica) and in Europe. It is also said to occur in eastern North America. It is a rare species in Germany.
Systematics
Inquiry systematics
The pale yellow blubber is the type of the subsection Citrinae , which is below the section Russula . The representatives of this subsection have more or less yellow hats and taste very hot. Another representative from this subsection is the sun-deaf , which looks very similar, but has yellowish spore powder. Molecular DNA studies show that the two species are not particularly closely related. The pale yellow blubber shows a much closer relationship to the spit blubber.
meaning
The pale yellow blubber is not edible due to its pungent taste and may be slightly poisonous like the very similar spit blubber.
