On last (4th) photo, P. hesperium on left, P. glycerrhiza on right. I'll bet you recognize this site, and might even remember the trip @eralverson. I think that was the first time I was shown the species...
The last photo is a close-up of spores from this plant showing the uniform shape and size typical of a fertile species.
Same plant as observation: https://www.inaturalist.org/observations/108704828
Uncommon plant about 2dm tall.
Among rocks at base of talus slope.
Also with C. acrostichoides (bottom-right) in the last photo
