Description

The cap of Leccinum griseum can be from 3 to 10 centimeters wide. It has a convex shape when young, while older specimens have a more opened shape. The cap color can vary from yellowish brown to a dark grey color. The stipe is relatively tall, usually from 8 to 15 centimeters, and there are usually many dark warts on it. The stipe changes color when touched, to a dark grey or even black. The pores are white colored (or eventually grey) and are relatively long. The spore print is brown.

Chemical reactions

The flesh reacts with potassium hydroxide, thereby forming a brownish orange color. The reaction with guaiacol produces a bluish grey color.

Habitat

This is a relatively common species, which mostly grows near hornbeams, but can also be found near oaks, chestnuts and poplars. This species can primaraly be found in Europe.

Season

Leccinum griesum grows mostly from June to October.

Edibility

Edible, and of very high quality. The stipes of older specimens may be a bit tough, and should thereby be removed (and not used for consumption).

Similar species

Almost all species with which Leccinum griseum could be confused, are edible and almost of equal quality. Most of these species don't change color that fast and that intensively as Leccinum griseum does. Thereby, the danger of confusing this species with a poisonous one, is very low.
