I noticed there is yellowish L.vouauxii photographed by C.Bjork on Ways of Enlichenment.

Well apparently so does Lepraria vouauxii!

At least the specimen I saw was fully leprose, and keys out to L. vouauxii (or some rare boreal thing which I’ll just ignore for convenience!)

Then it’s probably something else altogether, then!

Only Lepraria neglecta regularly grows in full sun, I think.

This yellow Lepraria (or whatever it is)

actually grows in the open quite often – I see it on sandstone bluffs all the time.

This doesn’t look leprose

The yellowish one, at least. (The bluish-white one looks like typical Lepraria.) Try Leprocaulon instead… is it even reported for the Great Lakes region?

Interesting observation that the crust appears to be extending the range of the normally shade-loving Ramalina intermedia! Of course both Lepraria and Leprocaulon also love shade… so what gives! :) There is something clearly unusual about this site…

I just added few more photos showing Ramalina intermedia

that grows only over Lepraria on this boulder (bottom three photos). Interesting detail – the spot is in full sun, facing south, except maybe in summer when it’s in partial shade. Does growing over this particular Lepraria allow R.intermedia to tolerate sun better? It’s supposed to be species of shade.

The item of interest here is yellowish Lepraria

It stands in stark contrast with other Lepraria types. It also hosts a healthy growth of Ramalina which tends to shy away from immediately adjacent white Lepraria
