Habitat: P. involutus occurs in natural forest in our region but is not common there. It is much more common and abundant in parks and landscaped areas, where it is typically associated with birches, often along with Leccinum scabrum and Lactarius plumbeus

Conservation Status: Not of concern

Edibility: Species of Paxillus can cause hemolysis (destruction of red blood cells) if eaten repeatedly, and have been responsible for deaths in Europe. Therefore, they should be strictly avoided as edibles.
