googling Paecilomyces farinosus gets a spot-on image for Allen’s photo. But Isaria is the new genus name for it, according to this reference here:

Looks suspiciously like something from Plantae too … top is
kind of fern-like. See what happens in a few days if there are
any left around there.

That’s beautiful Alan, what was it fruiting from, something in the sand or the sand itself?
I wonder if it belongs in Isaria or Cordyceps?
