gorgeous photos, Ryane.

and what a curious bolete this is! not sure that either of you fellows are correct, tho…I assume that you can taste bitter Ryane, so that would seem to eliminate coniferarum. Maybe another taste test would tell the tale?

Is the cap color as captured “true”? It seems a pretty good match for young coniferarum (listed in BR and B as dark olive gray). Its gestalt really doesn’t look like appendiculatus. Too bad you didn’t save it! Next time…;)

It has reddish/brownish spots/tinges at the base of the stipe.

B. coniferarum can and most often is very brownish-red at the base —
see the photos below. In fact I have not seen many photos that do not
show that at least a bit. Bessette’s description mentions no reddish
on the stipe, but it is in complete contrast to his photograph… as
far as the base of the stem is concerned.

Look at the photos at Bessette et al, Ammirati & Trudell. — in all
cases the stipe shows brownish, reddish discoloration to various
degrees. These are early fruiters. We do not have that many choices
out there to play with.

not B. coniferarum

although the photo doesn’t show this feature, the base of the stipe is red and pink. This feature is reportedly absent on B. coniferarum.

B. abieticola is in the Appendiculati group — Butter Boletes, mild tasting. I am familiar with the species and have photographed it on my site.

This collection seems to be in the calopus group (“Bitter Butter Boletes”) by the looks alone and I questioned it not being bitter. This reminds me of the Oregonian B. coniferarum…

P.S. Also, Irene, B. abieticola has a completely different fruiting window in the higher elevations of Sierra Nevada, early to late summer. Ryane is collections at elevation 20-40m where you can hear the Ocean surf…

P.P.S.

It is very common for people to misinterpret the taste, particularly on young material, or if they were rather shy to take a big bite and chew it sufficiently long – sometimes it has a pronounced after taste… We’ve been held hostage of that taste holdups before.. therefore I suggested we imagine the World outside of it

says “taste mild”..

Has got to be bitter…

Looks bitter and almost certainly acts that way, except for the material being young. We have a lot of B. rubripes (coastal variety) in that area. In this case it reminds me of B. coniferarum, which is a more Northerly species, fruiting rather earlier. I am not aware of other records from Calfiornia, but this being Spruce over there, it is quite likely to be.

This is one is in the B. calopus group more than the Appendiculati…

Ryane, I know where you collected this one – if you see any Corts in that locale, please seize and desist… :-)

Maybe Boletus abieticola?
