Description: This is a lichen of high ground that has the appearance of a Porpidia and the discs of an Aspicilia. The grey or rust-coloured thallus is cracked like a mosaic into areoles, each of which usually bears a single flat disc (to 1.5mm diam.), often with a central ‘pip’ of tissue or umbo. It grows on damp schistose rocks, often on exposed scree. The spores are simple, almond-shaped. In Ireland: Brandon Mountains, County Kerry and Connemara, County Galway.

Key Identification Features:

• Thallus grey or rust-coloured, rather elegant in appearance: like a Porpidia with Aspicilia-like discs
• Discs flat sometimes with an umbo. Mountainous areas; on rocks (schists) and stable scree.
