External description

At first, the cap is bell-shaped, cone-shaped, then it becomes prostrate and depressed. In the center there is a tubercle, grooved edges. Slimy, shiny and clammy skin. Rather dense, cylindrical, thin stem. Rare fleshy, wide plates, slightly descending, sometimes with a continuation in the form of thin lines on the top of the leg. Loose white flesh with a weak but sweet taste and pleasant smell. Elliptical smooth white spores, 11-15 x 6-9 microns. The color of the cap changes from brown to olive green and darkens towards the center. Above the leg is white, below it is covered with ring-shaped growths.


Medium quality edible mushroom.


Sweetheart is found in coniferous and mixed forests, most often with spruce and pine.
