The Stropharia aeruginosa ( Stropharia aeruginosa ) is a species of fungus of the genus stropharia .
features
The Stropharia aeruginosa forms in hat and handle structured fruiting . The hat is 3–8 cm wide, bluntly hunched, later spread out flat, blue-green to chip-green and, with age, somewhat yellowish in color. It has a peelable hat skin thickly covered with mucus and remains of velum floating in it . The surface of the hat becomes sticky in dry weather. The brim of the hat is bent down for a long time, blunt and in young specimens hung with velum flakes. The lamellae, which are slightly bulged on the stem, are initially gray-white to gray-brown and later purple-gray to violet-brown in color. The blade edge is significantly lighter. The stem measures 4–8 cm in length and 0.4–1 cm in thickness. He wears a hanging, grooved ring in the same brownish purple color as the lamellas. It is hollow or full and sometimes thickened towards the base. The stem color above the ring is blue to blue-green when young, below blue to blue-green. The stalk has a flaky, flaky stalk bark when young, which becomes bald with age.
The spore powder is purple-brown. The spores are ellipsoidal and smooth, thick-walled, 7-10 × 5 μm in size and have a germ pore . The species has club-shaped cheilo cystids , only the pleurocystids are formed as chrysocystids.
Ecology and phenology
The Grünspan-Trüsselling lives saprobion table in the deciduous and coniferous litter or very badly rotten wood. It prefers acidic, lime-free, nutrient- and nitrogen-poor soils and can be found in a wide variety of forest types, along paths, in gardens and parks and, more rarely, on meadows.
Its fruiting bodies appear in Central Europe from late summer to late autumn.
distribution
The verdigris is common in the Holarctic . It occurs from Asia Minor across the Caucasus to Eastern Siberia, Korea, Japan, the USA, Canada and Greenland, North Africa and the Canary Islands. In Europe, its distribution area extends from the Mediterranean to Scandinavia, the Hebrides and Iceland, as well as from Great Britain and France to the Baltic States and Russia. In Germany the species is widespread and common, but is increasingly endangered by forestry measures and fertilizer input.
meaning
The verdigris is edible, but not a valuable edible mushroom .
confusion
Easy to distinguish from species of other genera by the slimy, intensely blue-green hat and the white scales .
The Blue Trüsselling ( Stropharia caerulea ) differs in its lack of purple, spore powder and lamellae, which are brown in color. It also has a weaker ring zone and less severe scaling of the stalk. Microscopically it differs through utriform cheilocystids, which are formed as chrysocystids.
The rare whitish- blue truss ( Stropharia pseudocyanea ) occurs more in meadows and pastures, has a conical, pale whitish gray-green hat, a weaker ring zone and smells of pepper.
