Rigidoporus lignosus

Rigidoporus lignosus is a species of fungus in the family Meripilaceae. It is a white rot fungus, known for its ability to decompose lignin in wood, leaving behind the lighter-colored cellulose and hemicellulose. This process often results in a white or yellowish appearance of the affected wood, hence the name "white rot".

Taxonomy

The species was first described scientifically by Miles Joseph Berkeley and Moses Ashley Curtis in 1856. The specific epithet lignosus is derived from the Latin word for "wooden", referring to the fungus's wood-decaying habit.

Description

The fruit bodies of Rigidoporus lignosus are polypores, meaning they have pores on the underside of the cap where the spores are released. The caps can reach up to 30 cm (12 in) in diameter, and are typically orange to brown in color. The pores are small and white to cream in color. The flesh of the fruit body is tough and woody, and the taste is mild.

Distribution and habitat

Rigidoporus lignosus is found worldwide, particularly in tropical and subtropical regions. It grows on a variety of hardwood trees, causing white rot. The fungus is also a common cause of heart rot in living trees.

Uses

In some cultures, Rigidoporus lignosus is used in traditional medicine. For example, in Traditional Chinese Medicine, it is used to treat conditions such as asthma and bronchitis. However, scientific evidence supporting these uses is limited.
