Learned something new from you, as always!

This is an indicator species for the Sierras

If you could see the size of these things, you’d see they were 10x too big for Trentepohlia (in addition to being yellow instead of orange, due to vulpinic acid instead of carotene). Unfortunately there are a number of cryptic species, in both the fertile (L. columbianum) and the infertile (L. vulpina) groups, most of which don’t even have names yet. Since there is no sign of apothecia on these, maybe it’s best just to go with L. vulpina group and leave it at that. (The bright yellow color and high elevation suggest L. lupina, however.)
