Description

Name in North American Boletes: Boletus bicolor var. borealis

Genus: Lanmaoa

Genus 2: Baorangia (Soon to be transferred)
Genus 3: Boletus

Species: borealis

Species 2: bicolor var. borealis

Common Name:

Tells: Yellow or pale yellow stem flesh stains blue on top & reddish-brown by the base. Cap flesh slowly blues, but only by stem. Orange-red or red pores age duller & stain greenish blue. Red cap flat or convex when young, & dulls w/age.

Other Information: Cap flesh slowly blues, but only by the stem. Stem is colored like the cap, tapers downwards, & may sometimes have netting at the very top. Found from New England west to Michigan & northwards. Often confused with B. carminiporus.

Science Notes: DNA testing strongly suggests that this mushroom will end up in the genus Baorangia, but we will wait on the name change until those results are formally published.

Edibility: Unknown. This species used to be avoided due to the now-debunked myth about red pored mushrooms being inherently suspect. It is also true that Baorangia bicolor (a sister species) has been known to cause bouts of ill digestion at times. So no one can declare the species to be a good edible, but there is no longer a sound reason to assume it is not.

CHEMICAL TESTS:

NH4OH (Ammonia): No data.
KOH: No data.
FeSO4 (Iron Salts): Cap flesh has no reaction.
