Trametes hirsuta

A species of fungus in the family Polyporaceae

Trametes hirsuta is a species of fungus in the family Polyporaceae. It is a common wood-decay fungus that is widely distributed in temperate regions. This species is known for its distinctive hairy cap surface and its role in the decomposition of wood.

Description

Trametes hirsuta is characterized by its semicircular to fan-shaped fruit bodies, which can grow up to 10 cm in width. The upper surface of the cap is covered with fine, hair-like structures, giving it a hirsute appearance. The color of the cap can vary from white to grayish or brownish, often with concentric zones of different shades.

The underside of the cap features a pore surface with small, round pores. The spore print is white, and the basidiospores are cylindrical to ellipsoid in shape.

Habitat and Distribution

Trametes hirsuta is commonly found on dead hardwoods, particularly on oak and beech trees. It plays a significant role in the decomposition of lignin and cellulose, contributing to the nutrient cycle in forest ecosystems.

This species is widely distributed across temperate regions, including North America, Europe, and Asia. It can be found year-round, but it is most commonly observed in the fall and winter months.

Ecological Role

As a saprotrophic fungus, Trametes hirsuta is involved in the breakdown of dead organic matter. It is a white rot fungus, meaning it primarily degrades lignin, leaving behind the lighter-colored cellulose. This process is crucial for the recycling of nutrients in forest ecosystems.

Uses

While Trametes hirsuta is not considered edible, it has been studied for its potential applications in bioremediation and biotechnology. The enzymes produced by this fungus, such as laccase, have been explored for their ability to degrade environmental pollutants and in the production of biofuels.
