Features
Macroscopic characteristics
The fruiting body has a 1 to 3.5 cm wide, hemispherical to flattened, sometimes weakly buckled hat in the wet state has a sticky, dark brown hat skin in young specimens. It fades out in dry ocher - yellow. Occasionally, recent fungi volatile Velumreste the brim. The slats are wide grown on a stick, while only slightly rounded and are quite tight. Young pale ocher, they last a dark brown color with whitish edges. The stem is 3-6 cm long, fibrous and rough, hollow in age and often has a kleinknollige stem base with up to 3 cm long Myzelsträngen. The ocher surface is finely overspun to raufaserig clearly structured. The meat smells like flour or cucumber.
Microscopic characteristics
At the basidia usually two mature, but also 2-4 or almost exclusively 4 spores zoom. The elliptical, usually quite broad to oval and thick-walled spores are laterally slightly flattened and have a thick wall. They are 10.5 to 20 microns long and 7.5-12.5 microns - the size depends on the number of sterigmata on the basidia from. The spores show a up to 2 mm wide, truncated germ pore. The blades cutting densely covered with 20-45 (54 ) microns long cheilocystidia. They look bottle-shaped, at the top often capitate, rarely slender utriform. In contrast to the lamellar surfaces are no or only few cystidia. They usually have a habit utriformen or the same size and shape as the cheilocystidia.
Ecology and phenology
The Raustielige Ackerling populated lawns, pastures, meadows, as well as lean and dry grasslands. But it can also occur in forests and roadsides. The fungus colonized both nutrient-poor and nitrogen-containing habitats and can even man- influenced, disturbed places such as fields, meadows and dunes not stop. The species prefers loamy or sandy soils over limestone or silicate rock.
The fruiting bodies appear mainly May to September stragglers can be found until well into November. , In warm climates, they can seem almost the whole year.
Dissemination
The Raustielige Ackerling is widely used in Europe from Scandinavia to Italy and North America (eg California, Ontario, Quebec) and is also known from Australia and New Zealand.
System
The taxon was first described in 1821 by Swedish mycologist Elias Magnus Fries as Agaricus pediades. 1889 Victor arranged Fayod the species of the genus Agrocybe to.
