On my property we get flushes of brownish/purplish bitter Tylos that have had me guessing for the past few years. I think I’ve finally at least learned to recognize T. rubrobrunneus, but there is another type with stipe color not so mottled as the rubrobrunneus… I think it’s T. violatinctus. When they get old and faded, they pretty much all look the same.

This obs (107035) shows a type that I found in a fairly dense forest of mainly beech. The brown staining seems prominent. The long semi-rooting stipe seems to me to be an intersting character for a Tylo.

oops. I see you said bitter, beech etc….

I retract my guess and humbly slink away…It’s ridiculous how much bitter, old Tylopilus can look alike after their colors of youth have faded. plumbeoviolaceus, violatinctus both have almost identical boring, brown banality in old age….and that may even be true of old amateur mycologists…

if it’s not bitter and found with oak I’d venture T. indecisus…

which is out in CT now. Very slight reticulation at apex and ()unlike T. ferruginneus it usually has a portion of the upper stipe white. I’ve forgotten the chem tests but that should help too
