It does suggest that Leptonia as traditionally circumscribed is not a good genus. However, I noted that the type for Leptonia, Leptonia euchroa, was not included in the analysis so it isn’t clear to me at least Leptonia won’t one day be resurrected in some new form.

Thanks for providing the link to the article. This makes for a much more compelling argument than just saying "I heard there’s some molecular evidence for ".

The gist is that Leptonia is nested within Entoloma and not in a coherent way, either. It is a ¨bad genus¨
