Extract from Wikipedia article: Mycena leptocephala, commonly known as the nitrous bonnet, is a species of fungus in the Mycenaceae family. The mushrooms have conical grayish caps that reach up to 3 cm (1.2 in) in diameter, and thin fragile stems up to 5 cm (2.0 in) long. The gills are gray and distantly spaced. The spores are elliptical, typically measure 7–10 by 4–6 μm, and are white in deposit. When viewed under a light microscope, the gills have abundant spindle-shaped cystidia on the gill edges, but few on the gill faces. The mushroom is found in North America and Asia, where it grows singly or in groups on conifer needles, cones and sticks on the forest floor. It has a distinctive odor of bleach; the edibility is unknown. Similar species include Mycena alcalina, M. austera, and M. brevipes.
Mycena leptocephala is a small to medium-sized agaric fungus with a bell-shaped to conical cap that is 1-3 cm in diameter, typically grayish-brown to reddish-brown in color. The gills are crowded and narrowly attached, and the stem is slender and cylindrical. In St. Petersburg, Leningrad Oblast, and north-western Russia, Mycena leptocephala has been found growing in clusters on decaying wood, stumps, and other organic debris, often in moist, shaded areas such as forests and parks. The fungus typically fruits from late summer to early autumn.

Saint Petersburg, Russia, August 20, 2018Unnamed Road, Sankt-Peterburg, RussiaObservations of Mycena leptocephala in Leningrad Oblast and north-western Russia revealed the fungus growing in various environments. On a tree utilization site in Sosnovka Park, dark grey-brown bonnet mushrooms were found on July 22, 2017. A group of grey-brown nitrous bonnet mushrooms was also observed on the same site. In a pine forest in Lembolovo, nitrous bonnet mushrooms were seen on August 8, 2017. Later, on wood chips in Sosnovka Park, nitrous bonnet mushrooms were found on August 20, 2018, both singly and in groups. The fungus was observed to thrive on tree utilization sites and wood chips, suggesting a preference for disturbed or decomposing wood environments. The consistent appearance of the fungus in these areas over multiple years indicates its adaptability and ability to colonize available substrates. Similar habitats were found in north-western Russia.
