Two have worldwide distribution and one is just in Asia. Which one is sensu stricto?

According to my DNA analysis

of the sequences in Genbank, Polyporus arcularius from Costa Rica is the same as that from the USA, however the European sequences are different. Since Polyporus arcularius is a name from Europe, it probably can’t be applied in North America.

Since Polyporus tricholoma is a name from Cuba, it is more likely to be the correct species for this observation.

is widely distributed in North America.

I think Polyporus arcularius is a European species

Not sure if we get it in North America. I collected this so I could sequence it and find out.

Why not P. arcularius?
