Rigidoporus microporus

Rigidoporus microporus is a species of fungus in the family Meripilaceae. It is a white rot fungus, known for its ability to decay wood by breaking down the lignin and cellulose that make up the wood's structure. This fungus is found worldwide, particularly in tropical regions, and is often associated with rubber tree plantations.

Taxonomy

The species was first described scientifically by Miles Joseph Berkeley and Christopher Edmund Broome in 1873. The specific epithet microporus refers to the small pores on the underside of the fruit bodies.

Description

The fruit bodies of Rigidoporus microporus are shelf-like, and can reach up to 30 cm (12 in) in diameter. The upper surface is smooth and white to pale orange in color, while the underside is covered in small, white pores. The flesh is tough and woody.

Ecology and distribution

Rigidoporus microporus is a saprophytic fungus, meaning it obtains its nutrients from dead or decaying organic matter. It is particularly associated with the rubber tree, Hevea brasiliensis, where it causes a disease known as white root rot. This disease can cause significant damage to rubber tree plantations, particularly in Southeast Asia.

The fungus is found worldwide, but is most common in tropical regions. It has been reported from Africa, Asia, Australia, Central and South America, and the Pacific Islands.

Uses

In addition to its role in the ecosystem as a decomposer, Rigidoporus microporus has been studied for its potential use in bioremediation. The fungus's ability to break down lignin and cellulose could potentially be used to help clean up polluted environments.
