This tiny, non-lichenised ‘bark-pimple’ lichen is an epiphytic species of smooth-barked trees such as hazel. The thallus varies little (perhaps a shade) from the colour of the bark. Visually, it is similar in appearance to A. analepta (described elsewhere) but has smaller spherical discs (perithecia) and three-septate spores with a distinct perispore. In Ireland, the species is well distributed throughout.

Key characteristics

  • Like A. analepta but rarer, with perithecia smaller and spores three-septate with a distinct perispore
  • Mostly found on hazel.
