A few boletes and something interesting.

[John Smalldridge]

The first appears to be Boletus ornatipes except that it is very bitter and leaves a yellow residue on your hands.

The next is Pulveroboletus ravenelii

This is one of the difficult for me to ID red and yellow boletes.

And finally a B. edulis type that I left in the truck to study later and forgot about that dried out completely in its whole state. Maybe a new way to save herbarium samples.

The first maybe Pulvorboletus ravenelii since it supposedly has a coating of dry yellow powder (the name powdery sulphur bolete is quite descriptive) or Suillus americanus though that is supposed to have a yellow coating of slime and not powder (the name chicken fat mushroom sounds right).

Oh wait the second one is Pulvorboletus ravenelii.

I have no idea then.

[John Smalldridge]

I don't believe the first two photos are P. Ravenelii because of a lack of blue bruising of the pores and no ring on the stem.

I think the first one is Retiboletus ornatipes (same thing as Boletus ornatipes). Bitter flavor is not unusual in this species, except it's usually not very intense.

The red & yellow boletes become even difficult after the colors fade, which looks like this may have been the case with the ones in photos 6 through 9.

Last one looks like B. variipes.

Thanks Dave. I had already ID'd the last one as B. Variipes, but thought it was interesting that it had dried out completely in its whole state.
