Valuy is a species of mushrooms from the Russula genus of the Russula family.
The hat of the Valuy is 8-12 (up to 15) cm in diameter, yellow or yellow-brown. In young mushrooms, the cap is spherical; later it opens to almost flat, with a depression in the center and well-defined radial grooves along the edge. The skin is smooth, shiny, highly slimy, easily removable.
The leg is cylindrical or barrel-shaped, 6-12 cm long and up to 3 cm thick, white, often covered with brown spots, especially near the base. In the middle of the leg, an irregular cavity forms with age, and the leg, at the beginning is relatively strong, becomes very loose.
The pulp is very fragile, white, gradually darkens on the cut and becomes brown. Burning bitter taste, can cause nausea, odor unpleasant, similar to rancid oil.
Valuy plates of different lengths, frequent, narrowly accreted, whitish or dirty-cream, secrete a yellowish transparent liquid that dries up and leaves brown spots.
In some areas, this mushroom is also called a goby . It is found in various forests, but especially where there is birch, from July to late autumn. Prefers shady, humid places, especially often found in birch forests and forests mixed with birch. Fruiting profusely, singly or in small groups. Season: July to October.
From a distance, Valui is very similar to a white mushroom. Almond russula (Russula laurocerasii) differs in the smell of bitter almonds. Russula subfoetens gives a yellow coloration of the pulp under the action of alkali solutions, Valui does not give such a reaction. The Morse russula (Russula illota) is distinguished by yellow plates with dark to purple-brown edges; her smell is more like bitter almond.
Despite the pungent pulp with an unpleasant odor, Valui is edible, suitable for pickling.
