Coprinellus impatiens – Pin striped inkcap

Synonyms: Agaricus impatiens, Coprinarius impatiens, Coprinus impatiens, Psathyrella impatiens, Pseudocoprinus impatiens.

Common name: pin striped inkcap.

Russian name: Navoznik nedotroga.

Extract from Wikipedia article: Coprinellus impatiens is a species of fungus in the Psathyrellaceae family. First described in 1821, it has been classified variously in the genera Psathyrella, Pseudocoprinus, Coprinarius, and Coprinus, before molecular phylogenetics reaffirmed it as a Coprinellus species in 2001. The fungus is found in North America and Europe, where the mushrooms grow on the ground in deciduous forests. The fruit bodies have buff caps that are up to 4 cm (1.6 in) in diameter, held by slender whitish stems that can be up to 10 cm (3.9 in) tall. Several other Coprinopsis species that resemble C. impatiens may be distinguished by differences in appearance, habit, or spore morphology.

AI-generated description

Coprinellus impatiens is a species of fungus that belongs to the family Psathyrellaceae. It is characterized by its small to medium-sized cap, typically 1-4 cm in diameter, which is initially bell-shaped and later becomes convex or flat. The cap surface is often wrinkled or veined, and ranges in color from brown to greyish-brown. The gills are crowded, free, and turn black as the spores mature. This fungus has been found in St. Petersburg and Leningrad Oblast, where it grows on soil, humus, and decaying organic matter in forests, parks, and other urban areas. In north-western Russia, Coprinellus impatiens typically fruits from June to October, often in association with deciduous trees such as birch, alder, and willow.

AI-generated summary of observations

Observations of Coprinellus impatiens were made in Leningrad Oblast and north-western Russia. The fungus was found growing on burnt ground in Tarkhovka, near Sestroretsk, west of Saint Petersburg. On August 18, 2018, the inkcap mushroom was observed, with its gills visible. The species was identified as Coprinellus impatiens, although the identification is tentative due to the use of "(?)". The habitat of the fungus suggests that it can thrive in areas with disturbed soil and potentially high levels of nutrients, such as those found in burnt areas. Further observations are needed to confirm the identity of the species and understand its distribution and ecology in the region. The observations provide valuable information on the occurrence of Coprinellus impatiens in north-western Russia, highlighting its presence in Leningrad Oblast.
