What color is the flesh when cut?

Did you nibble a bit of the margin— was it bitter?

If yellow flesh and not bitter, possibly B. regius sensu Thiers

Not a bad idea

the B. coniferarum I’ve seen on the coast have a fine and sometimes obscure reticulum. I can’t really tell anything about the presence or absence of a reticulum from these pictures, other than that one is not immediately obvious.

But given especially the spring fruiting, and sort of atypical range for that species, my guess is still the B. frustosus/B. rubripes complex.

Has anyone confirmed B. coniferarum from the mountains? I would not be at all surprised to see them, especially in the Southern Cascades

Also maybe?

With the darker brown cap, there are periodic reports of Boletus coniferarum from the mountains also. These might be that? Although old dried out ones?
