This is a characteristic species of short, calcareous grassland. It is minute and gristly with tiny, shiny brown, cylindrical lobes (often less than 1mm wide) when wet, and a wrinkled, cellophane-like, lobe-shrivelled thallus when dry. The entire plant could fit the space of a one cent coin.

Key characteristics

  • The habitat, minutely shrivelled, foliose thallus and lack of abundant isidia are good pointers
  • Although there are other similar black, foliose lichens, most are flattened to the substrate or much larger
  • The miniscule L. teretiusculum is almost crustose with even smaller, brittle-looking lobes and is virtually invisible to the naked eye, unless abundant.
