Mayra's russula (Russula mairei)

External description

Mayra's russula has a cap-toed fruiting body, with dense white flesh, which may have a slightly reddish tint under the skin. The pulp of this mushroom is characterized by a pungent taste and aroma of honey or fruit. Upon contact with a solution of guaiacum, it intensively changes its color to a brighter one.

The cap of Mayr's russula is 3 to 9 cm in diameter, and has a hemispherical shape in young fruiting bodies. As the mushroom matures, it becomes flat, sometimes slightly convex or slightly depressed. The color of the cap of Mayr's russula is initially deep red, but gradually fades, becoming reddish-pink. The skin adheres tightly to the surface of the cap and can only be removed at the edges.

The leg of Mayr's russula is characterized by a cylindrical shape, very dense, often white in color, but at the base it can be brownish or yellowish. The fungal hymenophore is represented by the lamellar type. The plates in its composition at first have a whitish color, in mature fruiting bodies they become creamy, often grow with the edges to the surface of the leg.

Fungal spores in Mayr's russula are 6.5-8 * 5.5-6.5 microns in size, have a well-developed mesh. Their surface is covered with warts, and their shape is obovate.
