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,
