Psilocybe cubensis group phylogenetic tree * 3
    #27805070 - 06/04/22 12:25 AM (1 year, 7 months ago)

An ITS phylogenetic tree of the Psilocybe cubensis group that I made a couple of weeks ago.  One thing that is pretty clear from this is that Psilocybe cubensis evolved in Asia or Africa, and it's the same species worldwide.  Also there are some closely related species - these tend to have a bit less of an annulus than P. cubensis.

There are a few sequences in here that haven't been published anywhere yet.

Tempted to suggest it evolved in Asia since it appears to be more widespread there.

It appears that way, but Africa is pretty undersampled.  Asia also....

no idea what im talking about here, but i would suggest asia seems the likeliest.  otherwise it wouldve had to cross a desert against prevailing winds right? i guess of course either way it did indeed cross a desert and then an ocean, unless it was back in the desert area before it became desert.
i am just conjecturing a speculative opinion thats likely already been taken into account. but just in case it hasnt and can assist in someway i decided to chime it in ; ). 
shouldnt the name be changed from cubensis either way now though?

:whathesaid: Id like to know the observable differences between all the species in this group!

P.cubensis, P.natalensis, P.indica and the two you mentioned.

One insertion and two substitutions in the ITS sequence, assuming that what I was sent as P. pseudoaztecorum really is that species.  There may be macroscopic, microscopic, habitat or distribution differences as well, but I don't have enough information to know for sure.  People who hunt mushrooms in Asia can help by sequencing collections that resemble cubensis but don't have as much of an annulus.
