Features

Macroscopic characteristics

Conocybe Tenera is a small, saprobiontisch living fungus. The hat is 1 to 2.5 cm wide and tapered to broadly bell-shaped. He is hygrophanous. Its tones range from light brown, ocher-brown or cream to cinnamon. The color darkens with age. Over time is a grooving the hat brim. Dried fruit bodies may be pale - yellowish. The hat surface is smooth. The lamellae are closely standing, attached narrow and ascending. Young they are usually light brown or beige, and later the hat ocher to cinnamon brown accordingly. Lamella tablets are intermingled. The fragile, long stem is hollow and near the top of frosting, the color is dull yellow or pale brown. He has a squirming grooving and is finely powdered. In length it measures 4 to 11 cm in diameter at about 0.15 to 0.4 cm uniform thickness. A ring or ring group does not exist. The stem base is partially thickened slightly but not bulbous. The meat is chewy, juicy and has a glassy. Odor of the fungus is mild. The flavor goes into the earthy Mushy.

Microscopic characteristics

The rather large, thin-walled spores are yellowish - brown, smooth and elliptical with an apical Keimpore. Dimensions yield 11-16 times 6-8.5 microns. The basidia are 20-26 times 8-9 microns in size and 4- sporig. The cheilocystidia measure about 17.5-25 times 10.7 microns. Caulo and cheilocystidia are lecithiform. Pleurocystidia are not present. The spore powder is light yellow to reddish - brown.

Ecology

The fungus lives in fertilized green areas such as meadows, fields or gardens and lawns growing on paths. Less commonly, it occurs in forests. Its distribution is limited to areas all over Europe and North America. The growing season extends from May to September at the latest.

Artabgrenzung

The fungus is, like all known Conocybe species, considered inedible. Possibility of confusion exists with the congeners milk white Samthäubchen (C. albipes ), which is often claimed comparable sites, or more similar colored gold dung fungus ( Bolbitius vitellinus ). A certain similarity also have some species of the genera of Ackerl Inge ( Agrocybe ), fertilizer Linge ( Panaeolus ) and bald heads ( Psilocybe ), such as the habitual comparable Spitzkegelige bald ( Psilocybe semilanceata ).
