This crustose species grows on worked timber (fence post, railings, etc.) and on the bark of evergreen trees in open, hilly districts. It is related to H. scalaris (described elsewhere) which has C+ red scales (squamules). H. caradocensis is C-, has rounder matt, button-like scales some of which may be lifting away from the substratum. H. friesii is very similar when young, but as it matures has more flattened scales which are shiny, not matt. In Ireland, it has been recorded from Counties Antrim, Clare, Tipperary and Wicklow.

Key characteristics

  • Thallus C-, with rounded, dingy matt, button-like squamules greyish-green to brown
  • On wooden posts, rails, debarked trees.
