Powdered flywheel (Cyanoboletus pulverulentus)

• Powdered flywheel
• Bolet is dusty

Description:

Hat: 3-8 (10) cm in diameter, at first hemispherical, then convex with a thin rolled edge, in old age with a raised edge, matte, velvety, slippery in wet weather, the color is rather variable and often heterogeneous, brown with a lighter edge, gray -brown, grayish-yellowish, dark brown, red-brown.

The tubular layer is coarsely porous, adherent or slightly descending, at first bright yellow (characteristic), later ocher-yellow, olive-yellow, yellow-brown.

Spore powder is yellow-olive.

Leg: 7-10 cm long and 1-2 cm in diameter, swollen or expanded downwards, often taperingly thinned at the base, yellow at the top, finely speckled in the middle part with a red-brown powdery punctate coating (characteristic), at the base with red -brown, red-brown, rusty-brown tones, intensely blue on the cut, then becomes dark blue or blackish blue.

Pulp: firm, yellow, on the cut, the whole pulp quickly turns dark blue, blackish-blue color (characteristic), with a pleasant rare smell and mild taste.

Common:

From August to September in deciduous and mixed forests (often with oak and spruce), more often in groups and singly, rare, more often in warm southern regions (in the Caucasus, Ukraine, the Far East).

The similarity:

Powdered flywheel is similar to the Polish mushroom, which is more frequent in the middle lane, from which it differs in a bright yellow hymenophore, a yellow speckled stem and a quick and intense blue in places of the cut. It differs from rapidly turning blue Duboviki (with a red hymenophore) by a yellow tubular layer. It differs from other Bolets (Boletus radicans) in the absence of a mesh on the leg.
