Chemistry would help

I’m sure an expert would know off the top of their head, since this is such a beautiful and well-photographed specimen. But it’s a bit ambiguous to me: it looks a lot like C. macilenta… except the tips of the podetia look more brown than red to me. If you could test directly for usnic or barbatic acid (both are KC+ yellow/orange, though not always easy to diagnose) then you could be sure one way or another. The keys also lead to two species I don’t really know, C. cylindrica and C. ramulosa, the former with dense “isidioid” granules covering the podetia, the latter with finely incised squamules. Neither sounds right.
