May mushroom,

May mushroom (English Calocybe gambosa ) is an edible mushroom of the Ryadovka genus (Latin Calocybe) of the Ryadovkovy family.

Biological description


With a diameter of 4-10 cm, in young mushrooms it is hemispherical or cushion-shaped, relatively regular rounded, opens as it grows, often losing its symmetry - the edges can bend up, take wavy outlines, etc.; in dry weather, the head of the May row may become covered with deep radial cracks. The crowded growth also leaves its mark: as the caps mature, the caps are pretty deformed. The color is from yellowish to white, in the central part it is rather yellow, in the periphery it is more or less close to white, the surface is smooth and dry. The flesh of the cap is white, dense, very thick, with a strong powdery odor and taste.


Frequent, narrow, adherent to the tooth, almost white in young mushrooms, light cream in adults.

Spore powder:



Thick and relatively short (2-7 cm in height, 1-3 cm in thickness), smooth, cap-colored or slightly lighter, whole. The flesh of the leg is white, dense, fibrous.


The May mushroom begins to bear fruit in mid or late May on lawns, forest edges and glades, in parks and squares, on lawns; grows in circles or rows, forming well-visible "paths" in the grass. Disappears completely by mid-June.

May mushroom is considered a very good edible mushroom; one could argue with this (after all, the smell!), but this requires at least practical experience.

May mushroom, May mushroom, St. George mushroom, calocybe May - how many names for one, even a very good, mushroom! It is interesting with what persistence and fearlessness the mushroom dedicated to St. George plows furrows in the capital's lawns; the city allows him more than any other representative of the mushroom kingdom. Still, its people at the very top are a matter of extreme importance even for the mushroom.
