Squamulose lichen

Source: Wikipedia, the free encyclopedia.
Placidium arboreum is a squamulose lichen with squamules that become green when wet.

A squamulose lichen is a lichen that is composed of small, often overlapping "scales" called squamules.[1] If they are raised from the substrate and appear leafy, the lichen may appear to be a foliose lichen, but the underside does not have a "skin" (cortex), as foliose lichens do.
