Description

Genus: Boletus

Species: nobilissimus

Common Name:

Tells: Red- to yellow-brown cap pitted, often greatly. White pores age to greenish-yellow. Tastes sweet. Stem very netted, sometimes raised.

Other Information: Only confirmed find in an Letchworth State Park, N.Y. but reliable sources have seen it elsewhere too. Very similar to B. atkinsonii.

Edibility: Good.

Science Notes: Whole genome testing of the porcini clade has created questions about whether the name should be changed to B. variipes, with that species being moved into the long forgotten “B. leptocephalus.” The confusion apparently comes from mixed up labels at (or on their way to) the herbarium level.

CHEMICAL TESTS:

NH4OH (Ammonia): Cap skin stains deep red-purple. Pores stain brown. Stem stains pale red-brown on the brown portions.
KOH: No data.
FeSO4 (Iron Salts): No data.
