Sweet! I have a print of this!! I just swiped some of the spores onto MEA plates a few days ago.
Let's hope for some sclerotia!

Hmmm.. I just looked at this page, Mycotaxon Submissions.
So anyone can write up the paper? Is a certain degree (PhD) needed?

Remember that if this species is described by someone else before you publish something then your name won't stick. If I was you I would write up the description and save the naming for last. That way you can be sure that the name you pick is the one that you want the mushroom to be known as officially. Plus, if you don't make the name official through a respected journal then the name you pick could be invalidated like the first name. Write that description and submit it for peer review.

ITS sequences mutate quickly, right?

"Sequence comparison of the ITS region is widely used in taxonomy and molecular phylogeny because it a) is (due to the high copy number of rRNA genes) easy to amplify even from small quantities of DNA, and b) has a high degree of variation even between closely related species. This can be explained by the relatively low evolutionary pressure acting on such non-functional sequences"
"The ITS region is now perhaps the most widely sequenced DNA region in fungi. It has typically been most useful for molecular systematics at the species level, and even within species (e.g., to identify geographic races). Because of its higher degree of variation than other genic regions of rDNA (for small- and large-subunit rRNA), variation among individual rDNA repeats can sometimes be observed within both the ITS and IGS regions. In addition to the standard ITS1+ITS4 primers used by most labs, several taxon-specific primers have been described that allow selective amplification of fungal sequences (e.g., see Gardes & Bruns 1993 paper describing amplification of basidiomycete ITS sequences from mycorrhiza samples). ITS region is nowadays being used to know the genetic diversity among different strains of bacteria by sequencing the ITS gene."
