White boletus hat:

Whitish in various shades (cream, light gray, pinkish), cushion-shaped, in youth it is close to hemispherical, then it becomes more prostrate, although it rarely opens completely, unlike ordinary boletus; cap diameter 3-8 cm. The flesh is white, tender, without any special smell and taste.

Spore layer:

White when young, becoming greyish with age. The holes of the tubes are uneven, angular.

Spore powder:

Olive brown.

Leg of white boletus:

Height 7-10 cm (in dense grass it can be even higher), thickness 0,8-1,5 cm, tapering at the cap. The color is white, covered with white scales, which darken with age or when dry. The flesh of the leg is fibrous, but softer than the ordinary boletus; at the base acquires a bluish color.

Spread:

White boletus occurs from mid-July to early October in deciduous and mixed forests (forming mycorrhiza mainly with birch), prefers damp places, willingly grows along the edges of swamps. It does not come across very rarely, but it does not differ in special productivity.

Similar species:

It differs from the closely related common boletus (Leccinum scabrum) in the very light color of the cap. Other similar species of the genus Leccinum (for example, the notorious white boletus (Leccinum percandidum)) actively change color at the break, which is the reason for combining the concept of “boletus”.

Edibility:

Mushroom, of course edible; in books he is scolded for being watery and homely, unfavorably compared with a normal boletus, but I would argue. The white boletus does not have such a stiff leg, and the hat, if you manage to bring it home, emits no more water than the hat of an ordinary boletus.
