It should be B. frustosus

This specie was wrongly demoted into a varietal rank of B. calopus — which is a big and very obvious mistake as they do not look quite similar at all and I know both well. The molecular data supports the speciation too. Someone has to simply put a quick paper together and straighten the matter…

apparently B. coniferarum is a PNW species…

with a darker cap than calopus when young, less pronounced reticulation and no red on the stipe (as Christian mentioned). Rubripes has a smooth stipe, completely red in age, and w/out reticulation.

They all have yellow pores.

Photos of all three in the Bessettes Book, as well as descriptions in Thiers, and a nice treatment of coniferarum in “Mushrooms of the PNW” by Trudell and Ammirati.

It’s better with bitter?

Good to know!

I am still becoming acquainted with high country boletes as well. Been finding B. edulis var. grandedulis for a couple weeks now in lodgepole pine-aspen forest. You should encounter some good specimens with all this precipitation we are gratefully receiving. Good Luck!

Also doesn’t have that much red (or any) on the upper stipe, from what I’ve heard.
I hope to find both when I head up to the North Sierra soon.

debating between B. calopus and B. coniferarum, but i guess coniferarum has whiter tubules than this specimen. The reticulation on the stalk is indicative that is isn’t B. rubripes from what I have read. Thanks for the input!

One of the bitter boletes

B. calopus or perhaps B. rubripes, although the latter may have a paler cap – I don’t have field experience with it.
