Crustose lichen: grey, brown or olive, smooth or lumpy forming tightly concentrated networks of dark-bordered, map-like mosaics. Discs minute, embedded in the bark, dot or fleck-like often in thin wavy lines. Mature shaded trees, waysides, woodlands, also on sheltered rock.

Key characteristics

  • Densely mosaic-forming especially on heavily shaded or old tree bark
  • Minute apothecia forming broken lines of dots and dashes like multiplying colonies of rod-shaped bacteria.
