Description
Genus: Boletus
Species: chippewaensis
Common Name:
Tells: Pale yellow cap, usually w/brick-red smears. White pores age to yellow (even gray-green in age) & may bruise reddish. White netting on buff to pinkish brown stem. Likes Norway Spruce.
Other Information: White cap flesh DNS. Cap can be viscid when wet. Pores get darker & yellower w/age, eventually getting a bit of olive. Pores sometimes stain pinkish cinnamon. A close relative of the true Boletus edulis. Has a strong preference for Norway Spruce though it will grow with other conifers.
Science Information: At least one eminent gene jockey believes this species has DNA so close to the European B. edulis that it shouldn’t be described as separate species. Suffice it to say there is an ongoing debate, and if you are in the Northeast the names “chippewaensis” and “edulis” can be alternated with a lot more freedom than your local club expert may be willing to admit.
