Features
Macroscopic characteristics
The 5-10 cm broad hat is young and brownish hemispherical, then flattened and darker only in the middle, often cracked. The crowded lamellae are fine, first whitish and brownish in color later by the spore powder. The 5-12 cm long and about 1 cm thick stem has a whitish color and has a ring just below the hat. The flesh is firm, white and light brown at the base. It smells normal.
Microscopic characteristics
The spores are elliptical, and of a brownish color.
Ecology
The thermophilic fungus lives on Pappelstrünken, occasionally also on other deciduous trees.
Importance
Cultivation
The Southern Ackerling is edible. He was already cultivated by the Romans, with mature slats were distributed on poplar wood. In Italy and Japan, he is grown and marketed today.
Ingredients
The Southern Ackerling is a unique extracellular enzyme, a functional hybrid of heme - thiolate Haloperoxidase and cytochrome P450 -dependent monooxygenase represents ( Agrocybe - aegerita peroxidase = AAP). It is inter alia capable of brominated aromatic compounds such as phenol and oxygen function ( OH groups) selectively introducing (for example, benzene, naphthalene, pyridine, thioanisole ) in a little activated molecules. The enzyme uses hydrogen peroxide as co-substrate and can therefore be referred to as peroxygenase. It is expected that similar enzymes that hold a promising biotechnological potential, in other agarics ( Agaricales ) occur (among others in the genus Coprinus ).
