Parmelia adaugescens

Parmelia adaugescens is a species of corticolous (bark-dwelling) foliose lichen in the family Parmeliaceae. Originally described from Japan in 1890, this lichen is widespread across Asia, occurring from Pakistan through the Himalayas to Japan and Taiwan, where it grows on tree bark in humid temperate to subtropical forests. The species forms rosette-shaped growths 8–15 cm across with long, overlapping lobes that have a shiny surface marked by conspicuous pale pores, and it produces relatively large ascospores with a thick outer wall that help distinguish it from related species. It is often found growing alongside other large-lobed Parmelia species in environments ranging from lowland to montane forests, favouring areas with consistent humidity throughout the year....read more on Wikipedia.
