This rare Irish epiphytic lichen is only known from one site in south-west Ireland. One reason for its rarity may be its similarity to the commonplace Arthopyrenia analepta (described elsewhere), a species of twigs and small branches which is told through a lens by the presence of a silvery, halo-like ring around the perithecial discs. J. sericea has almost identical discs and ring and so this enables it to avoid detection. However in J. sericea the spores are muriform (not one-septate). It grows on the smooth branches of hazel and oak.

Key characteristics

  • Like A. analepta but with muriform spores; on branches of hazel and oak
  • Search for it among the old woodlands of south-west Ireland.
