The most delicate mushroom (Marasmius wettsteinii) is an inedible mushroom from the family of non-flippers.

External description of the mushroom

The tenderest mushroom (Marasmius wettsteinii) is a small-sized mushroom, consisting of a cap and a leg. The tiny size, in fact, determines the reason for the classification of this mushroom as inedible and not of particular nutritional value.

The mushroom caps are characterized by a diameter of 2.5-7 mm. At first they have the shape of a hemisphere, and then, when the mushroom ripens, they open. In their central part there is a characteristic brown hump. The hats are very thin, have a wavy edge and radial folds on the surface. in fresh mushrooms, the color of the caps is white, and subsequently turns brownish. The most delicate hymenophore is represented by white plates slightly adhered to a barely distinguishable collar.

The stem of the fungus is characterized by a shiny surface of dark brown color, covered with small hairs. Its length is 2-6 cm, and its thickness is 0.4-0.8 cm. The size of fungal spores is 7.5-10 * 3.5-4.8 microns. They are ellipsoidal in shape, smooth to the touch, and have no color.

Habitat and period of fruiting

Active fruiting of the most delicate non-fertile plant (Marasmius wettsteinii) lasts from July to September. This type of mushroom grows in mixed and deciduous forests, on a coniferous bed of spruce (rarely fir) needles. Even less often, the most delicate non-nippers can be found on fallen pine needles.

Similar species, distinctive features from them

In terms of its external characteristics, the most delicate nonnium is similar to the bristle-legged nonnium, however, in the latter, at a young age, the cap is characterized by a brownish color, and in addition, this type of fungus forms curves of black rhizomorphs.
