Observation 48686: Boletus rex-veris D. Arora & Simonini

When: 2010-07-01

Collection location: Lake Tahoe, California, USA [Click for map]

Who: dan harder (iblewit)

Specimen available

A happy amateur, I’d like to think this is an aereus — HOWEVER, certain features don’t fit, namely, the pileus is rimose (in as much as I understand the term), pitted, and was scaled in patches not only on older specimens but on the button pushing up through the duff. The pileus was light brown, yellow-brown, and with patches of red-brown. The taste was like an edulis, though a bit nuttier (very nice flavor, though we spat it out). No part of the flesh (cap, tube and pores, stipe — either top or bottom) bruised in anyway (blue, red, whatever)and we gave it plenty of time. Spore print was fairly dark olive. Smell slightly fishy. Fairly dark, almost reddish reticulation at top of stipe. Pores olive colored in young and old. In one of the photos, it is side by side with a rex-veris found the day earlier at a higher elevation (white pored). We found no other such specimens other than in this landscaped and often watered area.

Note the rimose (cracked) cap on this young un’. This is what throws me.
