Unfortunately I don’t have a scope (or any reactants), but I have these dried (any many others), waiting for the day I do. :)

there are a couple of similar corts in CA and S. CA, all having that reddish-rusty brown sporedrop.

Here’s one example from the San Diego area:

and another from Yosemite, part of the Yosemite Fungal Survey:

DNA will eventually get run on the Yosemite collections.

Beautiful cort here Evan, regardless of name!

Some information regarding reactions to alkaline reagents and also spore dimensions and ornamentation would be most revealing!

Nice photos:)
