Collection location: Franklin Parker Preserve, Chatsworth, New Jersey, USA [Click for map]

Who: I. G. Safonov (IGSafonov)

No specimen available

This is the first time I collect this particular species of Tylopilus, and the best match I could get was T. peralbidus — based on the photos and description in the big bolete book (distribution north of NC has not been cofirmed). Three mature specimens growing in shade on the side of a sandy road under mature oak and pines. The stipe is very smooth, devoid of reticulation, whitish bruising brown quickly. Taste is mild. Exposed context slowly staining pinkish-brown.


Pictures #1-3 = photographed on site when fresh
Photographed 2 min following dissection
Staining of the context with 3% KOH (aq)
