Extract from Wikipedia article: Mycena cinerella, commonly known as the mealy bonnet, is an inedible species of mushroom in the family Mycenaceae. It is found in Europe and the United States, where it grows in groups on fallen leaves and needles under pine and Douglas fir. The small grayish mushrooms have caps that are up to 1.5 cm (0.6 in) wide atop stipes that are 5 cm (2.0 in) long and 2.5 mm (0.10 in) thick. Its gills are grayish-white and adnate, with a "tooth" that runs slightly down the stipe. The fungus has both two- and four-spored basidia. As its common name suggests, it smells mealy.

AI-generated summary of observations

The observation of Mycena cinerella in Leningrad Oblast and north-western Russia revealed that the fungus grows in clusters on moss-covered tree trunks, stumps, and other decaying wood. On October 22, 2016, a group of Mealy bonnet mushrooms was found near Orekhovo, north from Saint Petersburg, Russia. The caps of the mushrooms were grayish-brown with a powdery coating, giving them a mealy appearance. The gills were crowded and white, attaching to the stem. The stems were slender and hollow, measuring up to 4 cm in height. The habitat was characterized by moist, shaded areas with abundant moss growth. The observation suggests that Mycena cinerella is a common species in the region, thriving in environments with high humidity and decaying organic matter. Further observations are needed to fully understand the distribution and ecology of this fungus in north-western Russia.
