Description: Formerly called Fuscidea hibernica, this lichen was originally described from Ireland, hence the specific name. It is still only known from its north Kerry site where it grows on sheltered, vertical acid rock. It can be told in the field by the grey-green to chocolate brown thallus, and the pale ochre colour of the powdery soredia which test C+ red. Discs are unknown in the Irish material.

Key Identification Features:

• Thallus grey to brown cracked into small 1mm-diam. islands with an ochre clouding of powdery soredia; C+ red; Schismatomma umbrinum is C-.
• Vertical faces of sheltered acid rocks; in gullies.
