Thank you, Lisa, for sending in the material. It will eventually be submitted for sequencing.

Thank you!

I am glad you saved it, L. Kimmerling, and thank you for posting, of course. There is nothing wrong for posting unknowns — folks come here for help all the time and they get it frequently as there are a number of excellent identifiers browsing the site.
I will send you my mailing address via MO right after I am done with this comment. If you don’t get it (some ISP’s block MO correspondence or mark it as SPAM mail), let me know through this observation.

I try to be as descriptive as possible! I am still a newbie to mushrooming, but I am absolutely captivated by the fungal world! I apologize for posting so many Unknowns here on MO, but I’m still trying to wrap my head around all of the diversity out there!

I have a large chunk of the cap that I am drying out if you would like a sample. How would I go about sending it?

If you save this collection, I would be interested in a sample for DNA sequencing.

You are welcome

I am not quite sure what you have here as the fruitbody is quite old and beat up. By the way, thank you for a detailed description. The flesh of L. griseum, a European taxon, stains violet, but the same staining of the cap is rather unusual. Its inclusion in BENA is rather interesting. The taxonomy and nomenclature of this species “warrant review” as per Kuo et al. 1

Thank you, @IGSafonov! I still need to acquire that bolete guide!
