Identifying Your Bolete
Habitat
Non mycorrhizal. Under ash trees and on lawns. In Outaouais, Quebec, we find the Ash-tree Bolete fruiting on an old stump and a decaying trunk of a Poplar Aspen.
Pores and Pore Surface
Pores angular, interveined, very large, 1 mm or more in width; the ribs going from the center to the margin are a sure criterion for its identification.
Flesh
White or yellowish, unchangeable according to the literature, but it may turn blue when cut in older fruitbodies and more intensely towards the base of the stipe. More rarely, it can be reddish in color.
