Porpidia hypostictica
Porpidia hypostictica is a species of saxicolous crustose lichen in the family Lecideaceae. Found in Jilin, Northeast China, it was described as a new species in 2015. It is characterised by its white to grey-white thallus with yellow, oxidized patches near the edges. It contains hypostictic acid as the only major secondary metabolite; its species epithet refers to this lichen product.
