Description

Genus: Boletus

Species: variipes-fagicola

Species 2: variipes var. fagicola

Common Name:

Tells: Dark brown-black cap often cracks & fissures w/age & hot weather. White pores age dingy yellow. Oft-bulbous stem usually has white or brown netting.

Other Information: Regular variipes has a much lighter cap and stem. Thought to be only from Michigan, John Plischke III identified the photos in this post from a sample found by Kate & and Scott Pavelle 7-28-2015 in Indiana County.

Science Notes: Whole genome testing has confirmed that this is indeed a separate species, and not variation on the far more common B. variipes. Note that many finds of B. atkinsonii have been proven to be B. variipes-fagicola, so do not be surprised if you cannot distinguish between the two.

Edibility: Choice.

CHEMICAL TESTS:

NH4OH (Ammonia): No data.
KOH: No data.
FeSO4 (Iron Salts): No data.
