Squamulose lichen

A squamulose lichen is a lichen that is composed of small, often overlapping "scales" called squamules.

[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.
