This grey to green, shrubby-tufted, often ragged lichen epiphyte is occasional on basic-barked trees in well-lit, often isolated situations: parklands, estates, waysides and should be first compared with R. canariensis. The two species are often confused, but in R. lacera the wide, reticulated branches (>1cm across) are relatively solid and not hollow or inflated. Powdery soredia are revealed through ulcer-like cracks on the surface. Discs are unknown in Irish material. It can be more abundant in exposed, coastal areas.

Key characteristics

  • Branches, flattened, wide and reticulated; never hollow or puffed-out (inflated)
  • Cracks along the edge and on the surface develop into ulcers from which spills powdery soredia.
