Laetiporus sulphureus
Common Schwefelporling ( Laetiporus sulphureus )
The common Schwefelporling ( Laetiporus sulphureus [A 1] ) is a species of fungus in the family Stielporlingsverwandten. The species was formerly placed in its own family of Schwefelporlingsverwandten ( Laetiporaceae ). Young, juicy specimens are edible and taste like chicken cooked. This has the fungus introduced the name " Chicken of the Woods " in the English language.

Features
The vielhütigen, often very large and conspicuous consoles have bright sulfur -yellow to orange colors and often grow at higher altitudes on tree trunks. The hats are spread out flat and mostly like a fan. The surface is velvety hairy, the edge is bent down and often zoned. The vivid sulfur yellow colored bottom is porous and wavy, the pores are irregular pulled round or slightly elongated, per millimeter are 3-5 pores. On the fruit body bottom Guttationstropfen are often formed. The tubes are about 5 mm long, the tube layer will not peel off. Fresh specimens are soft and juicy, the elderly become brittle and chalk or cheesy.
Ecology
The common Laetiporus is a parasite which, preferably less common on deciduous trees to conifers. In the wood, he creates a striking brown rot. As a substrate, he prefers hardwoods with color core, it can infest oak, locust, Prunus species and pastures in Central Europe rarer ( at higher altitudes ) conifers ( larch) are populated. In Central Asia, larch species are colonized by Dörfelt, also in North America conifers are affected. The Schwefelporling can also colonize other deciduous shrubs. Often the infested trees are too old or damaged.
The fungus enters through wounds in the tree, and first decomposes the heartwood. In the following also the sapwood is attacked, leading to increased wind damage susceptibility of host trees. In the shrinkage cracks thick mycelial lobes are formed. He can live on for a long time as Saprobiont until the substrate is completely consumed after the death of the host.
Of course, the Schwefelporling occurs in lowland forests and in more humid oak mixed forests. In addition, it is found in other types of forests, orchards, parks and street trees.
Dissemination
The Schwefelporling was detected on every continent, in the Holarctic he is particularly common in warmer and temperate regions. The European distribution area corresponds Krieglsteiner by the oak. In Germany it is relatively tight spreads.
Importance
The Laetiporus is a parasite that can cause intense brown rot and the death of the infested trees lead. The status and fracture strength of infested trees is greatly reduced. In black locust, the damage is often limited to the trunk.
Feed value
The fungus is edible in the very young state, it quickly becomes very tough and inedible, the raw Schwefelporling is considered toxic. There are observations that Schwefelporlinge, for example, have grown in oak or black locust, can trigger in susceptible individuals vomiting and diarrhea.
