Like Gyalideopsis, species in this genus possess structures called hyphophores but in Jamesiella these are isidia-like. J. scotica occurs on wet mountain slopes and along the edges of rocks and boulders in streams and rivers, sometimes attached to old liverwort or moss cushions. The thallus is like a smear of varnish and the pale brown hyphophores like small pegs, flaps or cones. Even though the hyphophores are microscopically small, they are somehow rather conspicuous under a hand lens. In Ireland, there are records from Counties Kerry, Donegal and Galway.

Key characteristics

  • Pale brown, peg-shaped hyphophores (0.1-0.3mm tall) on a varnish-like thallus
  • Upland streams, attached to decomposing liverworts and mosses.
