Mycena flavoalba

White Yellow helmet Ling ( Mycena flavoalba )

The white Yellow or Citron Mycena ( Mycena flavoalba ) is a species of fungus in the family Schwindling relatives ( Marasmiaceae ). It is a fairly small, pale yellow-colored helmet Ling with a more or less vivid yellow Hutmitte. Its spores are inamyloid. The fruiting bodies appear from May to November usually gregarious forests and meadows.

Features

Macroscopic characteristics

The cap is 1-2 cm wide, tapered, curved to campanulate and later flat. In the age of the edge is finally bent upwards. The Hutmitte often wears a small papilla, whereby the hat appears stocking cap shaped. The hat is pale yellow to lemon yellow, the center is usually colored much stronger. The brim is grooved translucent and coarse.

The sometimes somewhat remotely located, whitish fins have grown bulged on a stick. You can have a pink glow sometimes. The blades are cutting the same color and the spore powder is white.

The long and thin looking, cylindrical stem is 4-6 ( 8) cm long and 0.2 cm wide. It is hollow and pale yellowish or almost colorless translucent. The smooth handle surface is completely fine frosted by Zystiden. The thin, translucent, yellowish flesh is pretty tough and resilient separates in violation of a water-clear juice from. The fungus smells and tastes normal.

Microscopic characteristics

The elliptic, 5.5-9.5 × 3.5-4.5 inamyloiden spores measure microns. The smooth cheilocystidia are bellied up bottle-shaped and often have a long extended neck. The hat skin is relatively kurzhyphig, in between there are thinner hyphae that bear many small extensions.

Artabgrenzung

The relatively frequent Yellow White Mycena can be relatively easily recognized with some experience. For a reliable determination but necessarily microscopic characteristics are to be used. A particularly important feature is the inamyloiden spores. Other important features are the dry stalk and the unstained, same color blades cutting.

The Stretchable Mycena ( Mycena epipterygia ) may look quite similar. His cutting blades can be removed with a needle as a gelatinous filament and its stem is coated with a rubber-like stretchable skin.

Ecology

The Yellow Helmet White Ling is primarily a type of mesophilic beech and fir-beech forests. It is found sometimes in hornbeam - oak and ash sycamore Schatt slope forests, and occasionally also in honey grass - oaks, oaks elms and Erlenauwäldern. In pine and spruce forests, he was detected. Furthermore, it occurs in forest and shrubbery borders, to half and full dry grasslands and not heavily fertilized, often moss -rich meadows, and along roadsides and in parks.

The fungus lives saprobiontisch on rotting leaves or needles, as well as on dead, strong vermulmtem wood. It can also grow directly on the ground. He loves bright, grassy or mossy places on predominantly neutral to alkaline, fresh soils that are well supplied with bases and nutrients and lockerhumos. As a substrate, it uses almost equally deciduous and coniferous wood, especially that of beech and spruce. The fruiting bodies appear from late July to the end of November, rarely do you find them earlier, but you can find stragglers to early January in mild weather.

Dissemination

The fungus was detected (USA), in the Canary Islands, North Africa (Algeria, Tunisia ) and Europe in North Asia (Israel, Caucasus), South America, North America. In the Holarctic he is meridional spread to boreal. In southern Europe, it is found from Spain to Romania. In the West it is found in France, the Benelux countries (often up quite often ) used and in Great Britain, where he northward though is rare, but up to the Hebrides. On the Irish island it is rare. It is found throughout central Europe and in Fennoscandia and in Estonia in the north- east. In Finland, its range extends northward to the 69th degree of latitude. In Germany the species is distributed widely. From the coastal areas to about the Main Line, he is quite patchy and scattered distributed, while it is moderate and non- stationary cases even fairly widespread common in southern Germany into the Alps.

Importance

The Yellow Helmet White Ling is not edible mushroom.
