Squamarina

Squamarina is a genus of lichens in the family Stereocaulaceae,^[1] although it has recently been suggested that it may belong in the family Ramalinaceae.^[2] They form patches of radiating lobes or overlapping scales, with a well-developed upper cortex and no lower cortex.^[3] They grow on calcareous soil and rocks.^[3] Squamarina lentigera can be used to make a yellow dye.^[4]
