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…D.
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?
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!
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!
