B. herbarum is a lichen of mossy, calcareous turf or limestone rock which can occur from sea level up to high level. The thin, slightly warted, varnish-like thallus supports flat, red-brown discs with orange tints in the persistent margin (exciple). B. bagliettoana (described elsewhere) is somewhat similar, but differs in the black discs and green epithecium. In Ireland, the lichen is very rare; north coast.

Key characteristics

  • Often among bryophytes on calcareous turf; thallus, white, varnish-like
  • Discs flat, red-brown; orange colours in the margin and hypothecium.
