Yes, much more common to the north.

Ryane’s (which I found and have the collection of) also had Grand Fir and Western Hemlock there too. It’s common in the Mushroom Corners area of JSF, probably with Hemlock, but the forest are so mixed in there it’s hard to pinpoint. And a lot of these conifer Corts jump to Tanoak as they come south.
I have never seen it in the solid Sitka Spruce groves of the far north coast, but is very common in the mixed spruce/fir/hemlock forest, once again next to impossible to pinpoint the associate without doing root-tip analysis.

Alan’s picture from the collection at the HBMS show last year was a small fraction of what I saw when I collected it.

There is Sitka Spruce at Salt Point.

camphoratus is more normally seen to the north…

too bad you didn’t save this, Darv. If confirmed, it might be a first record for SP.

Ryane Snow found it with Bishop Pine in Mendo, altho in the PNW I believe that it is more of a Sitka Spruce associate.

The nose dose know.

But does what’s behind the nose know that young camphoratus smells like old traganus? At least in CA…

camphoratus has a very strong odor, nasty, too, like rotting potatoes.

traganus can smell like over-ripe pears or goat musk (yum!).

the visual macro qualities may be variable, but the odors in this case are quite distinctive.

next time, scratch and sniff. ;)

suggests C. camphoratus as well. Purplish vs. light brown to cinnamon-brown for young C, traganus.

Flesh of young traganus

Flesh of young camphpratus

C. traganus seems like the best choice.

I do not remember the odor and I did not collect it. It was found on a SOMA foray and was quickly photographed. The base is so dark, too dark for C. camphoratus, and the mushrooms are very young, still with a fragile cortina. The upper flesh in the stipe could simply be not very mature yet and thus lacking the brown color.
