This is a brown fruited species with upright, 3cm-high, scaly stems (podetia) and narrow cups occurring on acid soils and dead and rotting wood. It is very variable but the rather large, thick-lipped, brown discs situated at the apices of the podetia are enough to indicate the species. It is common in suitable habitats throughout Ireland.

Key characteristics

  • The brown, convex discs which appear translucent when wet and the coarse peeling squamules on the upright podetia indicate this species
  • The untidier Cladonia squamosa can be very similar, but is Pd- while Cladonia ramulosa is Pd+ red. When wet, the halo of discs of C. ramulosa can often sit perched at the apices of the podetia and come to resemble miniature brown rubber rings.
