Similar to L. schrederi (described elsewhere) but closely adpressed, forming fan-like radiating rosettes to 1.5cm diam. These are dichotomously branched at the ends like Fucus seaweeds. The glossy branches are often ridged when dry with nodular outgrowths along the lobes. The habitat is moist, shaded limestone. Ireland the species is known from the Burren, County Clare but there are older records from County Sligo.

Key characteristics

  • Thallus, pale grey-brown, forming rosettes (<1.5cm diam.), dichotomously branched at the tips
