This rare Porocyphus is extremely scruffy so is easily missed while searching lake margins for lichens. It has a brown, minutely shrubby-granular appearance (which could easily be mistaken for isidia) composed of fragile, much-branched cylindrical lobes. It was reported from Lough Inagh, Connemara in the nineteenth century but there are no recent records. I have seen it growing along the edges of Llynnau Cregennen in west Wales and around Loch Lomond, Scotland, on basic to ultrabasic rock.

Key characteristics

  • Brown, minutely scrubby-granular thallus only resolved under a hand lens
  • Shaded lake margins on ultrabasic rock; never recorded from rivers.
