Description: This olive-brown, shiny, foliose lichen with rather stiff upright lobes and grey-white soralia along the margins, grows on trees, shrubs and fence posts. It is rather localized in Ireland despite its otherwise wide distribution. It is easily overlooked as Platismatia glauca but differs in the brown lobes which turn olive green when wet, and in the more brittle and smaller size. Throughout Ireland.

Key Identification Features:

• Leafy epiphyte: olive brown, shiny with stiff tufts of upright lobes
• Soralia on the edges of the lobes; lobes turn olive green in the wet.
