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. [2] Squamulose lichens are composed of flattish units that are usually tightly clustered. They are like an intermediate between crustose and foliose lichens.
Examples of squamulose lichens include Vahliella leucophaea , Cladonia subcervicornis and Lichenomphalia hudsoniana .[3]
