Boletus Aereus


The cap of Boletus aereus can be wide from 6 to 15 centimeters, and it mostly has a convex shape. The edge of the cap is usually bent downwards. The, usually, matte cap can come in various tones of dark grey or dark brown color. The stipe is relatively massive, and in older specimens, it is usually a bit wider at the bottom. The pores of the boletus aereus are very small, and are clogged in younger specimens, while in older specimens, the pores are round and opened. The spore print is greenish brown colored.


It grows near oaks, chestnuts and beeches. It often favours places where the sunlight can reach the ground for at least several hours daily. This species grows well in central and southern Europe.


In reaction with potassium hydroxide, it forms a light brown color. Contact with iron sulphate forms a light green color. There is no reaction with ammonia.
