The thallus of this rarity has been compared to L. lichenoides and L. gelatinosum. However, this distinctive species is blue-grey with rounded lobes. The matt upper surface carries a fine furry tomentum. Clusters of granular or lobe-like isidia are present. Usually it forms cushions on thick mossy mats of Isothecium myosuroides in humid, sheltered habitats often on the leaning trunks of oak and birch: County Kerry and west County Cork.

Key characteristics

  • Thallus blue-grey, lobes rounded with granular or sub-lobate isidia, densely furry in places
  • Cushion-forming on Isothecium myosuroides on oak and birch; south-west Ireland.
