the spores are typical of the genus Gyroporus…

which is, as you noted Doug, more typically an Eastern North American or European species. In “California Mushrooms, A Field Guide to the Boletes”, Thiers mentioned them as a rare but not unheard of find in Northern CA, with all of the earlier collections made by Dr. Walt Sundberg from one specific area in the Sacramento River Delta, under one specific tree (oak)! Other West Coast collections have been from OR and WA.

If you had Oregon oak among your tree associates in Sebastopol Darv, could this mushroom maybe also be an inadvertant transplant? Still, a cool find, and a good edible, but too rare at this point out West to sacrifice to the fry pan!

Thats a weird thing to see in Cali.

I didn’t think these were seen in California. Those spore at least don’t look like your normal Bolete spores. What about other Boletiod genera in California, more common ones, are there any of those that have spores that look like that?

wow Darv, nice find!
