This extremely uncommon lichen of clay banks and soft cuttings has a green, filmy washed-out thallus and round spherical discs without a hardened layer (involucrellum) immersed within it. The simple colourless spores contain an abundance of oil bodies. In Ireland, the species is very rare.

Key characteristics

  • Thallus a thin jelly-like film when wet; discs: immersed perithecia
  • Spores simple, colourless with oil bodies; on clay cuttings by roadside ditches.
