Looks like only two species of Chrysothrix common in Ozarks

C. xanthina on trees, C. insulizans on rock. Latter should be K+ reddish, and forms tiny round patches (which you can see in these photos).

Note that this is reported as C. chlorina in the Ozarks flora. Look instead at Lendemer’s sterile crust key. It also includes C. onokoensis (K- and more diffuse), but I found that there are no specimens of C. onokoensis for Missouri in the NYBG.
