Rhizomorpha subcorticalis

Rhizomorpha subcorticalis is a species of fungus in the family Meruliaceae. It is a saprophytic fungus, meaning it feeds on dead or decaying organic matter. The species is known for its unique rhizomorph structures, which are thread-like aggregations of hyphae that resemble plant roots.

Taxonomy

The species was first described in the scientific literature by the mycologist John S. Karling in 1936. The genus name Rhizomorpha is derived from the Greek words rhiza, meaning "root", and morphê, meaning "form". The species epithet subcorticalis refers to the fungus's tendency to grow beneath the bark of trees (subcortical).

Description

Rhizomorpha subcorticalis forms dense, white to cream-colored mats of mycelium beneath the bark of dead or dying trees. The rhizomorphs are typically 1–3 mm in diameter and can extend several meters through the soil or along the surfaces of logs and stumps. The fruiting bodies of the fungus are small, irregularly shaped, and cream to light brown in color.

Distribution and habitat

Rhizomorpha subcorticalis is widely distributed throughout the world, but is most commonly found in temperate regions. It is typically found in forests, where it colonizes the dead wood of a variety of tree species. The fungus plays an important role in nutrient cycling by decomposing wood and returning nutrients to the soil.

Ecology

As a saprophytic fungus, Rhizomorpha subcorticalis plays a crucial role in the decomposition of organic matter in forest ecosystems. It is particularly adept at colonizing and decomposing the wood of dead or dying trees. The fungus's rhizomorphs allow it to explore and colonize new substrates efficiently, and to survive in unfavorable conditions by transporting nutrients and water from areas of abundance to areas of scarcity.
