It didn’t make sense that I was expressing some uncertainty if the DNA was so similar to other sequences (“0.1% distant”). It was a typo that I have now corrected. I meant to say “1.1% distant.” That makes more sense.

Sorry for the slip.

Very best,

Rod

Awesome!

I’m hoping that Vicksburg, where I’ve since moved, proves to be as fertile a space for new species as Baton Rouge was.

A very good nrLSU sequence has been derived from the voucher of this observation.

We also have a terminal fragment of ITS that connects with the nrLSU sequence. It appears that the species may be new. For the moment, at least, we will give it a temporary code. The LSU is minimally 1.1% distant from all sequences deposited either in GenBank or our local database. The size and cap coloring seem rather distinct; however, having additional material would be extremely valuable.

The terminal motif for the start of nrLSU is of the more common form (“TTT…”) in this case.

We are snowed with molecular data and haven’t checked the spore size and shape yet.

Thank you very much for your continuing support and the fascinating collections.

Very best,

Rod
