External description

Hat: very small. It is only 0.5-1.5 cm in diameter. The hat has the shape of a hemisphere at a young age. Then it becomes prostrate, but not completely. A narrow and deep depression is visible in the central part of the cap. The surface of the cap is radially fibrous, with deep rises and depressions. At first glance, it may seem that under the skin of the cap there is no pulp at all, and that the surface of the cap is inseparable from infrequent plates. The caps are pure white at a young age and grayish yellow in mature and overripe mushrooms.

Flesh: the mushroom has a very thin flesh, almost none. The pulp has a hard-to-notice pungent odor.

Plates: plates adhered to the collar framing the leg, not frequent, white.

Spore powder: white.

Stem: very thin stem is up to 8 cm long. The stem is brown or black in color. The lower part of the leg is of a darker shade.


It is found in places of high humidity. It grows on dead trees, as well as on coniferous and deciduous litter. Marasmius rotula is found quite often, usually in large groups. Fruiting period from about July to mid-autumn. Due to its small size, the mushroom is very difficult to spot.


It differs from the same wheel-shaped mushroom – Marasmius bulliardii, while this mushroom does not have the same pure white color.


the wheel-like non-nipple is so small that it hardly contains poison.

Genus feature

the mushroom belongs to the genus Tricholomataceae. A feature of this genus is that the fruit bodies of Marasmius rotula have the ability to dry out completely during a drought period, and after rain they return to their previous appearance and continue to grow and bear fruit.


Other mushrooms belonging to the marasmus are rather details of the forest mechanism, and not ordinary mushrooms. Separate parts of this mechanism are scattered throughout the forest, and the system continues to function. In the process of ripening, the non-stinker somehow grows dull and dies, becomes the same as its numerous relatives. It can be identified by its wheel-like shape and a pronounced collar at the place of attachment of the plates. Although, a mature mushroom can hardly be called beautiful.
