and hot damn!

We got some DNA sequences!

Hi Debbie, I am a student in Dr. Matheny’s lab, and we got some very exciting DNA sequencing results from your secotioid Inocybe! I am looking forward to doing some more microscopy and writing some descriptions for this one. I can maybe send you some more details via email if you like…

looks good for a secotioid Inocybe!

Brandon Matheny peeked at this obsie and wants to sequence the mushroom.
There are only three species of secotioid Inocybes known worldwide (one a Auritella), all from Australia.

If so, this would be the first from NA! ;)

Geez, who knew there could be so many cheap thrills in the genus Inocybe?

thanks guys, for peeking at this odd fruit body.

I am gonna run it by Mathany and see what he thinks. He ran the DNA on a couple of other unusual Inocybes that I sent him. Plus, he could probably let us know if Inocybe is really out of the question here or a possibility.

All we have right now is silky cap, brown spores. Arora in MDM does list angular spores as one of the possible manifestations for Inocybes here in NA.

Regardless of basal genus, an interesting find.

apparent secotioid form.
