Your specimen looks pretty much like the entity or entities I find in the NJ Pine Barrens growing in association with pitch pines. I hear someone recently sequenced this material (not 1, but 3 loci!) and, not surprisingly, found no matches in GenBank for any of the 3 genes. The closest relation was a collection of L. piceinum , a conifer-associated species, from the heart of Europe. I think this kind of outcome is going to be true for most North American scaber stalks. It’s going to be a long and painful road to get this mess sorted out properly.

…is a European taxon to my knowledge. Many North American scaber stalk inherited European names, but most of species on this continent are likely to be very distinct from their Old World counterparts. I won’t be surprised if there is going to be a divide between the two coast and the mid-west arising from exclusive host-specific mycorrhizal relationships so common in Leccinum. The European Leccinum has already been studied pretty thoroughly through molecular sequencing means, while here in the USA it seems like we are light years away from that kind of effort — we are still using old names, most of which don’t apply, or names from Smith & Thiers’ The Boletes of Michigan.

This was found in a predominately pine forest area, but there may have been other trees near this collection (Douglas Fir and Cedar, mainly). I did not observe any color changes.

I was glancing at this site: http://www.alpental.com/...

It reminded me of this collection.

Do you have a habit description or a list of tree species growing in the vicinity? What about the color changes of the exposed flesh?

Does anyone recognize this species?
