Scytinium lichenoides

Description: This species bears a close resemblance to L. gelatinosum, but is essentially a plant of mossy tree boles and rocks in old, damp woodlands away from limestone. It can be distinguished by attention to the margins of the lobes from which arise fibril-like cylindrical extensions (isidia) giving the thallus a generally ‘bushy’ appearance, and the lower surface which is strongly wrinkled below. If discs are present these are frequently ringed with ‘eyelashes’ (isidia) which are never seen in L. gelatinosum.

Key Identification Features:

  • Usually on mossy tree boles and woodland walls away from limestone
  • Bushy with numerous fibril-like extensions, the thallus strongly wrinkled below with discs fringed with eyelash-like isidia.
