It’s a great match for sponsus.

Very best,


This one appears not to have been scheduled for sequencing.

That matter is corrected.


Thanks for the update Rod.

Good to hear you’re back fully restored and armed.

I’m sorry that you didn’t hear back from us. This material was accessioned into our herbarium around the turn of the year (subdrawer unit is labeled “December 2016”). The label also indicates that the specimen has not been sampled for sequencing. That is what I can report at the moment.

I had a computer crash on 18 October, and am just restored to operating condition as of yesterday evening. Full genetic database, herbarium database, etc. were rescued. Some older programs had to be replaced with newer versions. Anyway, I think the computer is working again. I was using Mary’s computer in the interim. So I kept up with some things.

Very best,


Thank you very much, Ron.

We’ll see what we can do at this end.

Very best,

I went back today to see if the one that I had left mostly buried had grown any.
It was still there and still mostly buried as was another smaller one (added photo).
As was the case with the Sonoma collection, this species seems to have a tendency to develop mostly underground.
I’ll dry these up and send the entire collection.

The spore measurements do fall in the range of what small sample I have recorded.

Can you spare part of the collection?

I’ve been hesitating in posting sequences because our sample size is still small. Since this material comes from a different county than the first material you sent, this would be worth sampling.

Very best,
