but odd that the “yellow in young pores” isn’t mentioned in the 2011 Buchwaldoboletus compilation paper here:

http://www.sciencebuff.org/...

Also, the “red and fresh” is mentioned in the same context as “droplets,” which tends to make me also believe “young.” Perhaps Harry just found another species of Buchwaldoboletus with young yellow pores, and assumed it was the same species, since saprobic boletes appeared to be a rarity at the time? I never found that reference where he stated such, though.

Whether the pores blue or not is also confused; no in the Thiers description of orovillus, but yes in some material w/yellow pores labeled orovillus (see MO sightings).

I think that we still have a lot of work to do to deliniate these saprobic boletes, especially to the point of doing accurate macro/photo IDs on em. Hopefully, you saved it and are running DNA samples with Christian. We have to start somewhere.

I certainly don’t feel comfortable doing sight IDs on them. Line up some more ducks, and maybe you’ll convince me; at this point, Buchwaldoboletus is about as far as I’ll go with this.

Sorry Debbie

I don’t have the energy or the time to get into an argument with you about this…
Rehash this: http://mushroomobserver.org/24056

According to Thiers’ original description, the pore surface for B. orovillus is bright red even in youth” Not true, he said “bright
red when fresh”
and later amended this when he found another collection.

spore data?

how did you make your determination, specifically how did you separate this from the many sp. of Buchwaldoboletus that also occur in the area?

According to Thiers’ original description, the pore surface for B. orovillus is bright red even in youth.
