Dermatocarpon species- Ghangaria Govindghat trail, Uttarakhand
VoF Week : Lichens for ID- MN160912: Lichen for ID please
On the Ghangaria Govindghat trail
Maybe Cetraria xizangensis
It may be a Lasallia species (family Umbilicariaceae). However, photograph is a fragment of thallus only and other details viz. morphological and chemical constituents are required for correct identification.
This lichen appears to me as Dermatocapron sp.
