Mountain Lichen

Dimelaena

Dimelaena is a genus of lichenized fungi in the family Caliciaceae. Members of the genus are commonly called mountain lichens, or moonglow lichens. They are placodioid crustose lichens, ranging in form from rimose to areolate. The genus has a widespread distribution and contains eight species.

Mountain

A mountain is an elevated portion of the surface of a planet, generally with steep sides that show significant exposed bedrock. Although there are no universally accepted definitions, a mountain is usually considered higher than a hill. By definition, mountains are often thought of as being a landform which is higher than 2,000 feet (610 m). It may either have a limited summit area or be a smaller plateau with high elevation and steep sides. A few mountains are isolated summits, but most occur in mountain ranges.

Lichen

A lichen is a hybrid colony of algae or cyanobacteria living symbiotically among filaments of multiple fungus species, along with bacteria embedded in the cortex, or "skin", in a mutualistic relationship. Lichens are the lifeform that first brought the term symbiosis into biological context.
