Variety borealis
Variety borealis has a slightly darker color scheme than the main species. The coloration in general is darker; the cap can vary from a bright apple red to a dark brick red with maturity, to almost purple in some instances. The pore surface has a varying coloration of orange red to red and becoming a dull brown red with age. The bruising coloration is a blue green and the spore print is olive brown. The distribution of variety borealis is relatively small, ranging from Michigan to the upper New England states. The similar distribution and coloration to Boletus carminiporus has caused the two to be confused.

Famous quotes containing the word variety:
“A third variety of drama ... begins as tragedy with scraps of fun in it ... and ends in comedy without mirth in it, the place of mirth being taken by a more or less bitter and critical irony.”
—George Bernard Shaw (1856–1950)
