Observation 218196: Boletaceae Chevall.
When: 2015-10-08

Notes: Dull red cap and a not especially vibrant yellow on the pore surface. Found growing on suburban lawn under oaks. Pore surface blues quickly. Context slowly or not at all. Stipe is red until nearly the apex, at which point the red intergrades with yellow. White mycelium is visible on the base.

A description of B. lewisii in the big bolete book can be found at this link:

Per your advice, I’m waiting for the upcoming edition of the Bessettes’ book. Without it (or its predecessor), I’m stuck with two guidebooks that are of no help here. Without the aid of microscopy – which is to say, with some considerable guesswork – Kuo’s key sends me to Boletus lewisii, which is as good a candidate as I can find.

Interesting collection…

It was a good idea to preserve this material…
Not much in the way of bluing, a healthy dose of red on the stipe, and the context is marshmallowy. They are not B. bicolor, but some of the morphology points in that direction. I wouldn’t be surprised if the two are closely related.
Anyway, who know what these might be… Have you tried to key them out in the big bolete book just in case?
