Collected by David Rust at Sea Ranch in mixed woods (tan oak, Douglas fir, redwood).

This is not fitting neatly into any known and described Bu. sp.

I have never seen this sp. before.

That brilliant yellow context, as well as the really not so red, starting out yellow pores (reddish orange only with age, similar to both some Xerocomellus and Bu. sp.), faked me out.

It has a mild, pleasant taste, too.

What really convinced me is when I looked closely at the fb with a hand lens (something that I didn’t do initially) it clearly showed punctate fibrils on the stipe, not netting.

TOO BAD almost all of the other western sightings of this unnamed species here on MO (B. erythropus sensu Thiers) lack photo documentation.

Not very useful to the myco-community, especially with a rarely encountered CA species.

But we’ve got a useful obsie, now. I will add micro soon.
