Observation 339473: Boletus edulis group

Notes:
Fruiting directly beneath Aspen in urban setting. No conifers within 100yards in any direction. This substrate has historically been proliferated with Amanita muscaria subsp. flavivolvata for nearly ten years. This season was dominated by countless true king boletes in varying stages of growth. The classic netted/reticulation, white stems, tan caps and white hymenium(fading/changing to green).

Two fruiting bodies are available for sequencing.

I have yet to send the sample. I was just mentioning that I was interested to hear his take on the association w/aspens. I had to track down his mailing address from our correspondence last season of the B. edulis var grandedulis. Mailed him a few B. edulis samples from a different location in Thurston CO. I am sending him the sample from this observation today and look forward to hearing back in a few weeks(if he indeed does sequence). Thanks again for your continued support and kindness. Keep in touch!

Thanks, Drew

So, what was Dr. Dentinger’s opinion on the nature of this mycorrhizal association?
Yes, I saw your porphyrosporus observation. Sure, I am fine with adding it to my herbarium, but, to be honest with you, I am not likely to be sequencing it any time soon. Still, it would be interesting to find out if NA collections from both coasts are conspecific with the European taxon and vis-a-vis each other. A few years ago I sequenced one of my eastern collections of porphyrosporus but I don’t think I chose the right locus to answer that question.
As to mushroom hunting, I am pretty much done for the year. :-) I really need to work on straightening out my herbarium… But the season is just beginning for you, my friend, and you’ll be busy. Have fun in the woods and be safe!

Thanks, Igor!

Already have a dried/bagged collection for Dentinger and was excited to hear his opinion of the association w/Aspens. I also thought of you with my recent Porphyrellus samples. Let me know if you’re interested ;). Take care and happy hunting!

Very nice, Drew!

Looks like fungal gods are treating you quite well this season. :-)
The rugolose caps and the unusual association with aspen make it a curious collection. Other than that they look very much like the northeastern edulis, including the purplish discoloration… I am sure Dr. Dentinger will be interested in a sample.
