I’m at a complete loss…

how you are having so much difficulty understanding this…

Maybe you should try e-mailing Alan asking if he is interested in adding this collection to his phylogenetic tree.

Do you think that these explanations are enough?
Florida, Italy and Washington, Italy and Mexico are points in a map. Do they have another meaning?

He did explain it…

“/papilionaceus clade 1 – Contains Galeropsis desetorum, in addition to Panaeolus papilionaceus collections from Florida and Italy
/papilionaceus clade 2 – Contains P. papilionaceus-like species from Washington, Italy and Mexico”

Without DNA evidence we can not know which one of these clades your observation would fall under and without more work on those collections or others with DNA we still have more work ahead of us to figure out what the real P. papilionaceus is. The bottom line is that DNA evidence has shown there is more than one P. papilionaceus in Europe.

Finally, I could access the link provided by Byrain in a previous message
My first thought was: Ok, “someone” give some results about his work; But, what credit can we give to it? Since “someone” is one of our partners on MO, Alan Rockefeller, maybe he can explain to us his work and where can we find it. In particular, what in his work is relevant for this observation, and by extension to similar observations?

That’s my usual state. Coming from certain people I use it as a compliment.
The matter is that was can not open the link you supply, my compute doesn’t permit!

Look at the link I provided.

what are the clades?

If you refer to varieties of P. Papilionaceus, I know at least three. But these all belong to the same species and are not a group of species.

There are two different P. papilionaceus clades in Europe

Panaeolus papilionaceus. Never saw a reference to the others in Europe. Undescribed are … undescribed.

P. papilionaceus, P. rubricaulis, P. venezolanus and probably some undescribed species known from DNA, see here. http://www.shroomery.org/...

Panaeolus papilionaceus group?

P. antillarum and P. semiovatus have less pigment and should have sulphidia.

Microscopy added.
