Common name: bicoloured deceiver.

Russian name: Lakovitsa dvukhtsvetnaya.

Extract from Wikipedia article: Laccaria bicolor is a small tan-colored mushroom with lilac gills. It is edible, but not palatable, and grows in mixed birch and pine woods. It is found in the temperate zones of the globe, in late summer and autumn. L. bicolor is an ectomycorrhizal fungus used as a soil inoculant in agriculture and horticulture.

AI-generated description

Laccaria bicolor is a widely distributed ectomycorrhizal fungus. In St. Petersburg, Leningrad Oblast, and north-western Russia, it has been found to fruit in various habitats, including coniferous and mixed forests, often associated with trees such as Pinus sylvestris and Picea abies. The species typically grows in summer and autumn, forming small to medium-sized mushrooms with wavy, wrinkled caps that range in color from purple-brown to yellow-brown, and white to pale yellow gills. It has been recorded in several nature reserves and forests in the region, including the Karelian Isthmus and the Valdai Hills.

AI-generated summary of observations

Observations of Laccaria bicolor in Leningrad Oblast and north-western Russia reveal the fungus's presence in swampy areas and moss. In Sosnovka Park, Saint Petersburg, deceiver mushrooms were found on September 6, 2016, in a swampy area. A year later, on July 6, 2017, bicoloured deceiver mushrooms with unusually long stems were discovered in the same park, growing in moss, except for one upper mushroom. The fungus appears to thrive in moist environments, with sightings in both swampy and moss-covered areas. The variation in stem length suggests adaptability to different conditions. These observations provide insight into the habitat preferences and growth patterns of Laccaria bicolor in this region. Further study could reveal more about the fungus's ecological role and distribution in north-western Russia. The sightings in Sosnovka Park highlight the importance of urban parks as habitats for fungal species.
