we’ve derived a slightly larger piece of the nrLSU gene so that we now have just shy of the “first” 1100 characters of the gene.

Thanks again for this interesting material, Lucy.

Very best,

Rod

I got your note about the name.

I had hoped that you would like it.

I’m glad you did.

Very best,

This species was formerly given the temporary code name…

sp-AUS06,” which is now retired.

Very best,

We were able to get a goodly piece of the “proposed fungal barcode” gene…

from this material and it is a precise match to the sequence we earlier derived from “myrmeciae.” MO #84440 was the previous observation upon which that temporary code is based:

Thanks again for sending the material. I appreciate your efforts as always.

Very best,

This material has been received and accessioned to Rod’s herbarium.
Thanks,

The present species has a membranous and completely white volval sac that is not crumbling.

MO #65016 has a crumbling sac that is turning gray around its upper edge. Also, the latter has a stem that became quite dark where you touched it. That doesn’t appear to have happened in the present case. The cap seems somewhat lighter in the button in the present case. Both species are somewhat squat in overall appearance and have rather long marginal striations. There are distinct similarities; however the differences between the two universal veils and the stem staining of 65016 make we want to hold off on saying they are the same species.

I’m going to move up the priority for sequencing the 65016 material so that we get a chance to see that data sooner.

Very best,

Rod

Different from 65016?

Hi Rod,
I was wondering, do you think mo# 65016 could be a different vaginatae species? It was found in a different place than where I find these (but none as perfect as this one!). I think I sent you it (65016) but you know my memory…

That sounds great, Lucy.

As always, thank you very much.

Yes, of course! It has dried perfectly. Will post it during the week.

It would be interesting to see the spores of this species if it could be collected.

Dr. Wood described a few species of section Vaginatae with a pale grayish or pale brownish-grayish cap. They appear to be separable by spore size and shape in the original descriptions. They also are drawn with slightly different statures. I am not sure what conclusions can be made from the drawings; however, the drawing most like your photographs is vaginata sensu A. E. Wood…the other species being noticeably more gracile as illustrated. I do hope you can get dried material of this one, Lucy.

Very best,

Rod
