I’m still trying to learn P. tenella. Notice that many of these, young though they are and not forming full hoods yet, nevertheless have sort of convex tips, like maybe they’re considering forming hoods. The few specimens of P. tenella I’ve seen have even narrower and more elongate lobes and the tips curl back a little (especially once they’ve formed soredia). I think zaca has some good photos showing this. (Although, it’s entirely possible some of his alleged P. tenella are extreme forms of P. adscendens just like this observation. I don’t think he’s had the opportunity like you have to have an expert review his specimens.)

T.Esslinger was in town and checked all my Physcia-type specimen

All of my P.tenella turned out to be P.adscendens. It looks like in the environments where they are small and not doing well they don’t form hoods at all.

But so cute!
