AI-generated description

Protostropharia alcis is a psychrotolerant fungus that grows on dung, particularly of carnivorous mammals. In St. Petersburg and Leningrad Oblast, it has been found in urban and natural areas, often associated with fox and dog feces. In north-western Russia, the species is relatively common, with records from various regions, including the Murmansk Oblast and the Republic of Karelia, where it typically fruits in spring and early summer on dung in forests, tundras, and other habitats.

AI-generated summary of observations

Observations of Protostropharia alcis in Leningrad Oblast and north-western Russia reveal its growth habits and characteristics. The fungus was found growing on animal dung on the side of a road around Kavgolovo Lake, between Oselki and Toksovo, north of Saint Petersburg. On August 13, 2024, specimens were observed with rounded caps, and upon closer inspection, the underside of the mushroom displayed its distinct features. A close-up view showed the fungus's growth on animal dung, highlighting its coprophilous nature. The observations suggest that Protostropharia alcis thrives in this region, particularly in areas with abundant animal waste, such as roadsides and fields. The species appears to be well-adapted to the local environment, growing vigorously on dung deposits. These findings contribute to our understanding of the ecology and distribution of Protostropharia alcis in north-western Russia.
