Under poplars. The American specialist, Alan B. Bessette, tells us "under poplars and pines".
Pores and Pore Surface
Pore surface grayish to pale olive-brown in age, staining brownish when bruised; pores circular, 2-3 per mm.
White, staining purple-gray or blackish when cut, often the main colour change happen at the junction of the stalk and the cap.
FLESH: towards beige with KOH and NaOH, towards gray with FeSO4 and no change with NH4OH; towards pinkish, then brown and finally gray with phenol; towards pinkish at first then bluish gray at the end with formalin. CAP: darker brown with all reagents except formalin. TUBES: towards yellow with KOH, NaOH and NH4OH; gray with FeSO4; black with phenol and formalin.
During reforestation, poplars are often replaced by Jack Pine or spruces to create pure conifer plantations. Under these conditions, it is possible that the Orange-capped Bolete is associated exceptionally with Jack Pine or spruces, even if in nature it does not occur. Analyzes using the DNA technique will confirm this.
