I think I had used Phillips while first trying to ID this one. I see now that his online depiction of bolaris includes some material that looks a lot like this one, except maybe that there’s more white on the caps in Rogers Mushrooms. Bolaris does seem like the best fit.

C. bolaris is a medium-sized cort with a red floccose veil on cap and stem.

Peck’s croceifolius was described as a small and tiny species with an umbonate cap, orange coloured gills and yellow stem, looking like an intermediate between Dermocybe cinnamomeus and semisanguineus, and has been interpreted as a synonym to malicorius.

Yeah, a real eye catcher.

And that color in the pic is exactly what it looked like.

C. bolaris was one of the other possibilities I ran across. Is there any particular trait(s) observable in these pics that favors the bolaris ID?

what a cool cort!
