Known today only from oak lignum at Killarney, County Kerry, L. subtile is a tiny, easily told lichen species. Furthermore, the thallus is usually dense with globose, orange discs. The almost cylindrical lobes form tiny rosettes 0.5-1.5mm diam. (smaller even than those of L. teretiusculum) among the mossy sawn surface of tree trunks (basic lignum preferred) that have been left undisturbed for a few years. In Ireland, the species was formerly in Counties Galway and Cork.

Key characteristics

  • Thallus miniscule, densely fertile, with cylindrical lobes forming rosettes
  • On undisturbed (about four to six years) sawn wood surfaces.
