Plant of the Day (December 9th, 2011) - Trametes hirsuta (Fr.) Pilat.

Autumn time is fungi time, so today's article is about a fungus again. This time, it's Trametes hirsuta (Fr.) Pilat., a fungus from the Polyporaceae family. Common German names are e. g. “Striegelige Tramete” or “Filzige Tramete”. Again, I've found no English names, but the translation of the Latin name means something like “Rough haired Tramete” or “bristly Tramete”.

The fungi of the Genus Trametes have hemispherical mushrooms (Karposoma), which sit on dead trees and tree stumps, which are decomposed by the fungus. The mushrooms of T. hirsuta have 8 to 10 centimetres in diameter (3.25 to 4 inches). They are white or greyish with dark-grey, wavy zones. The whole dorsal site is covered with rough bristles, what gave the species its name. Sometimes, the dorsal site has some green spots, which is caused by symbiotic green algae. The growth area at the base of the mushroom is brown.

The ventral site is white and has many large pores, while the spores are ripe in autumn.

T. hirsuta is a scavenger, which lives on dead wood of trees, especially the wood of the beech Fagus sylvatica L. but also the wood of many other species; mostly deciduous trees and in some, rare cases also on conifers.

The species is spread over large parts of the Northern hemisphere and is native to Europe, Asia and North America, where it can be found in parks, woods and the Edge of forests.

This fungus is not edible. It's flesh is tough, hard and tastes very bad.
