nucleotide sequence,

According to Alan the nucleotide sequence is a match for P. ovoideocystidiata, the microscopic characters are also a match so I don’t know why we can’t agree that it is that species?

Regardless of whether or not these are Ovoideocystidiata, mushrooms don’t know where we say they do and do not grow. Our knowledge of where and when mushrooms grow is always expanding.

P. ovoideocystidiata only occured around the Ohio River Valley?

How could this be ovoideocystidiata?

I was talking to Alan about these specimens and he said that the sequencing for these turned out to be a match for P. subaeruginascens but to me the microscopic characters are a match for P. ovoideocystidiata, it may be possible that the two species are synonymous and the microscopic characters for P. subaeruginascens are a lot more versiform than the original description shows!

The microscopic characters here are a better match for P. ovoideocystidiata.
The pleurocystidia here are globose-pyriform and a good match for the second type of pleurocystidia described for P. ovoideocystidiata.

For P. subaeruginascens the pleurocystidia would be broadly fusoid-ventricose with an obtuse apex.
