I’m tickled to death to actually be making a difference. Hope to send you more previously unknown specimens.

The large gray species appears to be novel.

The sequence is not somethings that has been sequenced before. The sequence is distinct in large single gene trees for both nrITS and nrLSU.

So I think we can work with a temporary code name while we are assembling more data.

Thanks for sending this interesting material.

Very best,
