I’ve seen C. thiersii in the spring in Washington State near the snow line. The spore measurements fit this species. My notes for C. thiersii say: “KOH reactions: granular yellow to purplish red extra cellular pigments, depending on age of dried specimen”.

They do look something like C. thiersii

although the caps were a little more darker reddish brown than the photos show.
Also, the C. thiersii is normally found in the Sierras during the spring.
