Tricholoma colossus
Tricholoma colossus is a mushroom of the agaric genus "Tricholoma". Due to its ringed foot, it was previously classified as "Armillaria", even though it is otherwise clearly "Tricholoma". The cap is 6–30 cm wide, brick red to chestnut brown, hemispherical when young, widening later on, uneven, always with very thick flesh, surface slightly sticky, developing somewhat into scales. The stipe is thick, 2–5 (at the stem even 10) cm thick, solid. Ring-like formation at the top of the foot, above which it is white. Grows in pine forests to September to October; very rare.
