The excellent webcap (Cortinarius praestans) is a mushroom belonging to the Spiderweb family.
The fruit body of an excellent spider web is lamellar, consisting of a cap and a leg. On the surface of the mushroom, you can see the remains of a spider web cover.
The diameter of the cap can reach 10-20 cm, and its shape in young mushrooms is hemispherical. As the fruit bodies mature, the cap opens to a convex, flat, and sometimes even slightly depressed cap. The surface of the mushroom cap is fibrous and velvety to the touch; in mature mushrooms, its edge becomes pronouncedly wrinkled. In immature fruiting bodies, the color is close to purple, and in mature ones it becomes red-brown and even wine. At the same time, a purple tint is preserved along the edges of the cap.
The hymenophore of the fungus is represented by plates located on the back of the cap and adhered to the surface of the stem with their notches. The color of these plates is grayish in young mushrooms, and beige-brown in mature ones. The plates contain a rusty-brown spore powder consisting of almond-shaped spores with a warty surface.
The length of the leg of the excellent spider web varies within 10-14 cm, and the thickness is 2-5 cm. At the base, a tuberous thickening is clearly visible on it, and the remains of the cortina are clearly visible on the surface. The color of the leg in immature excellent spider webs is represented by a pale purple tint, and in mature fruit bodies of this species it is pale ocher or whitish.
The pulp of the mushroom is characterized by a pleasant aroma and taste; it acquires a brown color in contact with alkaline products. In general, it has a white, sometimes bluish color.
