One difference

vs pessundatum is the warmer brown cap colour in ustale. If you compare them, it’s more of a pinkish hue in pessundatum. And the stem darkens from the base and upwards in ustale, not that dark in pessundatum.

But I’m not quite convinced that every species in this group have got proper names yet..

I think this is different from the understanding of these, as applied to California. Which wasn’t really correct in the first place, so it isn’t like that matters. I’ll have to remember to look up that, when I get back to California. I’ll try to remember to look up source for Europe later today, to see what that says.

But what are the differences here that don’t look like T. pessundatum?

T. ustale is mild, slightly farinaceous
T. ustaloides har a slightly bitter cap cuticle
T. pessundatum slightly bitter

And it doesn’t look like pessundatum..
