I think late day lighting may have influenced the color as seen in the photo(s).

Originally, this collection looked to me like T. violatinctus based on the overall color scheme, and that is why I proposed the name to begin with. However, my low confidence in this name stems from my eventual interpretation of what appear to be olive-brown stains on the stipes — violatinctus shouldn’t do that. At the same time, the stipes of T. rubrobrunneus should be whitish or brownish when young, though Kuo says it can sometimes have a purplish hue, with the darker olive-brown tones gradually taking over as the mushroom ages. In my experience, the classic T. rubrobrunneus in good shape is one of the easiest Tylopilus species to identify. The ambiguity in color presented by the pix, whether real or not, doesn’t make this an easy ID.

It is difficult for me to put into words the color difference between these two species when young. Maybe it’s the reddish purple in rubrobrunneus. They do look different to me.

Thanks for the additional clarification, Walt.

But I do wonder about your level of certainty regarding this collection. Material which I have been highly confident to call rubrobrunneus is pretty similar to this.

The rubrobrunneus/violatinctus thing has been a real stumbling block for me. At least I think I have learned to recognize plumbeoviolaceus.

Igor, I think you’ve made a good point here.

I don’t see the olive tones on the stipes.

This day at Moon Lake was a late day “collecting frenzy.” There was all sorts of nice stuff to gather. It’s either feast or famine with wild mushrooms. When the weather is inviting, they ALL come out.

I had come upon several patched of purplish-capped Tylos this day. I recall at least some of them showing the olive tones on the stipes… but perhaps not necessarily these.

One is apt to wonder… why would I gather so many of these uber-bitter mushrooms? I know this wild foods expert, someone who loves a challenge. She claims to have a plan to turn bitter Tylos into a good edible food. So I’m preserving collections for her. I’ve got some that I am quite certain are rubrobrunneus, and today I gathered more. I also got a nice collection of felleus today. Felleus is the only species of bitter Tylo that is reported as edible. The others are all listed as “edibility unknown.” I’ll be certain to keep collections separate and explain the element of uncertainty to my wild foods friend.

Thanks for casting a bit of a shadow upon my ID.
