BTW, the durhamensis paper gives the location of the 2001 holotype collection — it only something like 15 miles away from where you found your mushroom.

when the confirmation works out. And this is a nice species to add to my local list we operating largely in the outskirts of Durham.

I think they are all the same species. Again the conclusion, naturally, made on the basis of your good photos.

similar also to this older observation Observation 215923?

In each of the observations the pore surface even of the “younger” specimens is dark.

The links you created are good — they are clickable. Thanks for doing this.

Thise is T variobrunneus. Even though the pore surface of a bit.

have to taste a bitter one for comparison one day!

I think linking them is great, is there a special way to do that or should I just mention the obs number in the notes?

Oh, and one more thing, Geoff…

I presume this is the same taxon as your obs 247926. If so, could you please link them together (for each obsie)? Thanks.

We both agree this is NOT T. felleus based on your tasting of this thing, right?

I was hoping it was a more unusual one. I’ve definitely seen a lot of T. felleus in this area.
Okay, Geoff

Thanks for confirming this important detail…
The pore surface color is off for T. felleus; however, the KOH test is in line with what’s reported in NAB/BRB.

IT tastes

For a moment I thought this could just be the Bitter Bolete. Did the flesh taste bitter?
