Lepiota aspera
Spitzschuppiger sting screen Ling ( Lepiota aspera )
The Spitzschuppige or Rough sting screen Ling ( Lepiota aspera, syn Echinoderma asperum, L. furcata var acutesquamosa. 193 and L. friesii: 193 ) is a species of fungus in the family of mushroom relatives. He quite often occurs in deciduous and coniferous forests, along roadsides and in gardens. The fruiting bodies appear from summer to autumn.

Features
Macroscopic characteristics
The first conical to bell-shaped, later flat spreading hat reached a diameter of 10-15 cm. The ochraceous - cream-colored hat skin is filled to the brim with pointed cone dense, brownish scales that form in the center even at the age a more or less closed ceiling. The whitish, later brownish lamellae are densely packed and are forked in stem near often. The 5-10 cm long and 0.5-1.5 cm wide stem has a bulbous thickened up to 2.5 cm, sometimes rimmed base. The Teilvelum hangs as ephemeral and membranous ring after Aufschirmen the hat on a stick. It has a whitish color and down on the edge brownish scales. About the ring of the stem is creamy, including hat colors. The surface is textured fibrous and flaky especially in the lower range. The white meat is smelly luminous gas -like: 193 or after the Stink - screen Ling (L. chris tata ) :57 -58.
Microscopic characteristics
The elongated spindle-shaped spores are 7.5-9 microns long and 2.5-3.5 microns wide. The cystidia on the fins cutting have a clavate - bubble-shaped to roundish - pedunculated shape and come sporadically on the vane surface before. 193
Artabgrenzung
The very rare Ringlose sting screen Ling (L. perplexa ) smells stronger and has no forked lamellae. The Kegelschuppige sting screen Ling (L. hystrix ) is darker in color and microscopically characterized by small, oval spores. The Hedgehog sting screen Ling (L. echinacea ): 194 is reminiscent of a miniature version of Spitzschuppigen sting screen blank - microscopic type by the absence of cheilocystidia be seen: 193 In addition, the inedible Spitzschuppige sting Schirmling possibly with the as. mushroom estimated Commons giant Parasol mushroom Parasol or be confused, which grows in a similar location. However, the latter has a double, freely movable ring and a nutty smelling and tasting meat.
Ecology and phenology
The Spitzschuppige sting Schirmling grows in deciduous and coniferous litter of various deciduous forests and spruce and pine forests, but apparently lacking in natural coniferous forests. He is regarded as nitrogen pointer and grows on base- and nutrient-rich soils. He is often found along roadsides under nettles and other waste places, it is rare in gardens, under hedges, to be found in fields or junipers. The fungus grows mainly 450-700 m above sea level, above it is rarely found. :58 -59
The type fruktifiziert mainly from August to late October, scattered stragglers can to December, are in favorable weather conditions also until January, I found. 58
Dissemination
Gminder (2003) cites in Volume 3 of the series The Great Mushrooms of Baden-Württemberg on Knudsen ( 1981) and defines the distribution area of the sting Spitzschuppige screen blank Australasian austrosubtropisch, boreosubtropisch to boreal. Records consist of Asia (Japan ) and America ( Argentienien, Canada, Mexico, Paraguay and the United States). In North Africa, the species occurs in Algeria and Morocco. In Europe the fungus in the Mediterranean ( Italy, former Yugoslavia) is found rarely. Otherwise, it is scattered to moderately common, but avoids oceanic tinted areas. 59
Relationship
Phylogenetic analysis of the American mycologist Else C. Vellinga indicate a close relationship of Spitzschuppigen sting - screen compact with the flour shield Lingen ( Cystolepiota ) and stained granules screen Lingen ( Melanophyllum ).
