Identical in the characters of the thallus phyllocladia with var. vesuvianum (described elsewhere) but differing in stalks (pseudopodetia) which are not congested, the upper parts smooth and bare and terminating in an apple-shaped soralium. It occurs along with var. vesuvianum and other members of the genus at former mine sites or on spoil tips. North and west Ireland, also the Wicklow Mountains.

Key characteristics

  • Thallus as in var. vesuvianum but with stalked soralia on long, bare pseudopodetia
  • Hard acid rocks and mine spoil.
