Protoparmelia badia is sometimes found in the ornithocoprophilous associations. See
L. García Sancho (1988) La vegetación liquénica ornitocoprófila de espolones en el alto sistema central español. Acta Bot. Barc., 37:223-236 (Ornithocoprophilous lichen vegetation on spurs from the high Sistema Centrala of Spain, a very interesting paper).
Dermatocarpon intestiniforme has perithecia, bluish colour with black lobes margins, thallus covered by pruina, and lobes in certain parts with intestine form (intestiniformes). Common in sub alpin stages, although normaly on calcareous rocks. Good description in G. Clauzade & C. Roux, Likenoj de Okcidenta Europo.
Molt interessants les "ornithocoprophilous communities" i en especial la foto que ens mostres. Felicitats per la captura i molt interessant l'explicació.
