Macroscopic features

Conocybe Tenera is a small, saprobiontisch living fungus . The hat is 1 to 2.5 cm wide and conical to broadly bell-shaped. He is hygrophan . Its tones range from light brown, ocher brown or cream to cinnamon. The color darkens with age. In the course of time, a grooving of the edge of the hat sets in. Dried up fruit bodies can be pale yellow. The hat surface is smooth. The lamellas are closely spaced, narrow and attached in an ascending manner. Young they are mostly light brown or beige, later ocher to cinnamon brown, depending on the hat. Lamellettes are mixed in. The fragile, long stem is hollow and frosted near the tip, the color is dull yellow or pale brown. It has winding grooves and is finely powdered. In length it measures 4 to 11 cm, in diameter in about 0.15 to 0.4 cm of constant thickness. There is no ring or remnant of a ring. The base of the stem is partially slightly thickened but by no means bulbous. The meat is tough, juicy and looks glassy. The mushroom has a mild odor. The taste is earthy and mushroomy.

Microscopic features

The rather large, thin-walled spores are yellowish-brown, smooth and elliptical with an apical germ pore. Dimensions are 11–16 by 6–8.5  μm . The basidia are 20–26 by 8–9 μm in size and have four spores. The cheilocystidia measure around 17.5-25 by 10.7 μm. Caulo- and cheilocystids are lecithiform. There are no pleurocystids. The spore powder is light yellow to reddish brown.

ecology

The fungus inhabits fertilized green areas such as meadows, fields or garden lawns and grows on paths. It occurs less often in forests. Its distribution areas are limited to all of Europe and North America . The growing season extends from May to September at the latest.

Species delimitation

The mushroom, like all known Conocybe species, is considered inedible. It can be confused with the milk-white velvet hood ( C. albipes ), which is related to the genus , and which often claims comparable locations, or with the more similarly colored gold dung mushroom ( Bolbitius vitellinus ). Some species of the genera of arable crops ( Agrocybe ), fertilizers ( Panaeolus ) and bald heads ( Psilocybe ) also show a certain similarity, for example the habitually comparable conical bald head ( Psilocybe semilanceata ).
