Porina huainamdungensis

Porina huainamdungensis is a species of lichen in the family Porinaceae. Known from Thailand, where it grows in lower-elevation montane rainforests, it was described as new to science in 2011. The specific epithet refers to the type locality, Huai Nam Dang National Park in Chiang Mai Province. The lichen lives on the surface of living leaves in the understory of montane rainforests, forming extremely thin, shiny greenish-grey patches with distinctive pale yellow-orange fruiting bodies. It has been found at elevations of 1,400–1,500 metres in protected areas of northern and northeastern Thailand, where it grows on the glossy leaves of shrubs and young trees in consistently humid, shaded conditions....read more on Wikipedia.
