I found this parasitized spider on the underside of a Pawpaw leaf (Asimina triloba) about 1 meter above the ground in Athens GA USA. A post on the Ascomycetes of the World FB group showed a similar spider and said it was Purpureocillium atypicola, which Wikipedia tells me is related to cordyceps.

We went on a night foray with UV flashlights. There were little bits of ground that reacted with this bright orange under the UV light. It is barely noticeable as a rusty powder on the leaf and needle litter when in daylight. When we picked it up this (mycelium?) powder was not visible on our hands in daylight but turned our hands bright orange under UV light.
I think it might have been a leaf litter decomposer.
