This is a weird one

The cap colors and intense red stains don’t look like the other R. griseus observations here, but I don’t have too much experience with the species. This is neat, it definitely merits a deeper look.

I find these red-staining types under pitch pines in the NJ coastal plain all the time in July and August (see my own obs #74396 and that of Martin Livezey from DE shore — #106350). Once I even collected them in a cedar bog. Time to sequence these and make a new variety of R. griseus.

mentions R. griseus var. fuscus, a Japanese species that has been found in Cape Cod. I know it’s a long-shot, but the bright red staining on the stipes in this obs is not something I recognize as typical for R. griseus. Also, looks like this collection may have been made under pine… I seem to recall a similar obs showing up some time back from North or South Carolina…?
