Description: This poorly-known species is nearest in appearance to L. hutchinsiae (described elsewhere) but the thallus is virtually inconspicuous or immersed; it grows on pebbles or along tiny limestone crevices. Discs not frosted; orange to dark brown translucent with a dark rim showing through when wet. In Ireland, the lichen is thinly scattered.

Key Identification Features:

• Like L. hutchinsiae but with no visible thallus; growing on fragments of rock, pebbles, and in fine cracks and crevices: limestone
• Disc orange to brown; translucent with a dark rim when wet.
