The tiny white things are the mites. Found inside a Coneflower Rosette Mite Gall (Family Eriophyidae) on Echinacea sp.

Photographed with a microscope.

Here is what the gall looks like:

The oblong orange thing is possibly a plant bug pupa for the same species as the nymph seen here:

iNat isn't able to give me meaningful suggestions,
Searching around for diseases of Purple Coneflowers, I find reference to "an eriophyid mite that causes the flower to develop lumps or bumps or leaf like structures growing out the side". (See link.) I also find references to "an eriophyid (family Eriophyidae) that has yet to be taxonomically categorized, so it has no scientific name or approved common name... generally referred to as the Coneflower Rosette Mite based on the damage that it causes to coneflowers". (See link.)
So I'm sticking it in Eriophyidae. Improvement welcomed.
