Stereocaulon alpinum

Stereocaulon alpinum (NL: Stereocaulon alpinum / EN: Alpine foam lichen / DE: Alpen-Korallenflechte / FR: Stéréocaule alpin) is a lichen. A lichen is a union between a green alga and a fungus. The fungus gains oxygen and carbohydrates from the photosynthetic activities of the alga, whilst the alga obtains water and mineral salts from the fungus. The fungus also provides protection against being washed away and from drying out in warm weather. This partnership is called a symbiosis.
