Trametes hirsuta

Trametes hirsuta, commonly known as hairy bracket, is a fungal plant pathogen. It is found on dead wood of deciduous trees, especially beechwood. It is found all year round and persists due to its leathery nature.[1]

The cap is whitish gray, with short hairs, sometimes yellowish and tomentose at the edge, and with subtle zoning. The flesh is tough with a soft gray upper layer and a whitish lower layer, separated by a black plane.[2]

Similar species include T. pubescens, which is unzoned, buff in colour, and without layered flesh. T. versicolor is more distinctively zoned.[2]


Lyophilized cell cultures of Trametes hirsuta yield aldehydes from alkenes, representing a biotransformation alternative to ozonolysis.[3]
