Cortinarius badiolaevis

Description:

Cortinarius badiolaevis produces mushrooms which each feature a smooth, brown to reddish-brown cap of between 2 and 5 centimetres (0.8 and 2.0 in) in diameter. The caps are initially hemispherical in shape, but as the mushrooms age, they become a low convex or even almost flat. There is a broad, blunt umbo in the center of the cap, and a white margin, covered in small fibrils. The cap is hygrophanous, meaning it changes colour depending on its moisture content. When moist, the surface is waxy and glossy. When it is dry, there is sometimes a zone of a different colour around the umbo, or radial streaks (that is, streaks from the center of the cap to the cap margin). The club-shaped stem measures from 3.5 to 7.5 centimetres (1.4 to 3.0 in) in height, and is 0.6 to 0.9 centimetres (0.2 to 0.4 in) thick. The stem is somewhat white, and, in texture, the surface can be silk-like or covered in fibrils. White mycelia are visible at the base. The yellowish-brown gills are neither closely nor distantly spaced, with between 35 and 42 approaching the stem. The gills are quite broad, and emarginate; that is, they are shaped with a notch next to the stipe, with the connection to the stem being shallower than the rest of the gill. As they mature, they lose the yellowish colouration, and become entirely brown. There is white-brown to light brown flesh in the stem, with darker flesh found in the cap. The smell is indistinct, or vaguely reminiscent of that of radish

Habitat:

Cortinarius badiolaevis is a rare species known from Europe; specifically, the species has been found in Spain and Sweden. It grows from calcareous soil in coniferous woodland, and is assumed to associate with pine and spruce.Specific trees under which the species has been recorded include Scots pine and the European black pine
