This inconspicuous lichen grows mostly on the leaves and stems of mat-forming mosses such as Hypnum cupressiforme agg., and willow bark. It looks very like A. muscigena (described elsewhere) and will apparently grow with it, but is distinguished by the three-septate spores and paraphyses with capitate apices. In Ireland, the species is known from the County Antrim coast.

Key characteristics

  • Very like A. mucigena but spores three-septate
  • On slightly bleached leaves of mat-forming mosses and on willow bark.
