• Melaspilea interjecta A.L. Sm.

There are no records for this species at present.

This rock-inhabiting scripture lichen has been recorded just once in Ireland from south Kerry. It is easily overlooked for Polysporina simplex owing to the swollen Opegrapha-like discs. It is attracted to vertical, smooth-surfaced slatey rocks. Spores 1723m long, shaped like a figure-of-eight, often breaking where waisted; older spores, brown, warted.

Key characteristics

  • Thallus scurfy, pale with grey, brown or green tones; discs very small (<1.5mm long), black, slit-like at first, then thickening
  • Spore cells (asci) eight-spored, spores one-septate (Polysporina simplex has multispored asci); vertical slatey rocks.
