On dry, sandy soils of heath and moor expect this cushion-forming lichen to be a frequent component of the lichen flora. The notched-tipped basal squamules, grey-green to brown above and white below with a hint of mauve are its dominant feature. The fruiting stalks (podetia) produce cups that proliferate from the centre. The thallus is K-. Throughout, except in central southern Ireland.

Key characteristics

  • The abundant basal squamules (2-3mm long) grey, blue-green or brown above, contrasting with the lower surface which is white with a mauve cast, is diagnostic. Podetia small, to one centimetre tall proliferating centrally. Dry, sandy soils and dunes.
  • The subsp. verticillata (described elsewhere) has poorly developed basal squamules and forms tall, multiple tiers from the centre of the cups.
