finally makes sense.

It’s been sequenced

and preliminary results suggest that it is not the same as the similar-looking Eastern species

Thanks for your input, Dave.

The cross-section shows a think brown wall that’s distinct from the rest of the context. I think this is typical of Gyroporus. One may surmise that the flesh will eventually turn brittle and get separated from the brown outer shell…

I don’t know the western NA G. castaneus.

These look somewhat like what I know from the east as G. castaneus. But I don’t feel confident about suggesting these are Gyroporus. None of the stipes have been snapped apart, and the sectioned mushroom shows a solid-looking inner stipe context.

Not sure…

…this is G. castaneus. It certainly doesn’t look like the chestnut bolete found in the Eastern USA. I do think it’s a Gyroporus species though, granted these are somewhat of a rarity in the West. Looks like these are mature, judging by the appearance of the pores surface, but the stipe flesh looks firm, not hollow and not brittle/stuffed, like one would expect for many Gyroporus species. If sequencing is performed, please post the results.

did these ever get the DNA run?

seems like a natural, considering its unusual and restricted distribution: Phil’s back yard and a river bottom in the Sacramento Bay Delta!

Samoa, huh? Too bad that one was a data free obsie. Not like this is a common western mushroom. Back it up, Dude.
