Description: The mossy trunks of broadleaved trees in old sheltered woodlands situated in the valleys of the north and west are the best places to search for this species. The grey-green, granular thallus covered with a patchy coating of pale-brown soralia can form thick crusts over mossy tree boles like apple-green emulsion paint. As discs are rare the certain identification of this lichen may depend on spot testing. All reactions are negative. Northern and western Ireland, rare.

Key Identification Features:

• Grey-green granular thallus forming thick continuous crusts (often to 20 or more centimeters)
• Discs usually absent; negative spot tests.
