Extract from Wikipedia article: Pseudoplectania nigrella, commonly known as the ebony cup, the black false plectania, or the hairy black cup, is a species of fungi in the family Sarcosomataceae. The fruit bodies of this saprobic fungus are small blackish cups, typically up to 2 cm (0.8 in) broad, that grow in groups on soil, often amongst pine needles and short grass near coniferous trees. Pseudoplectania nigrella has a worldwide distribution, and has been found in North America, the Caribbean, Britain, Europe, India, Madagascar, New Zealand, and Japan. The fungus produces a unique chemical compound, plectasin, that has attracted research interest for its ability to inhibit the growth of the common human pathogenic bacterium Streptococcus pneumoniae.
Pseudoplectania nigrella is a small, cup-shaped fungus that grows on soil, moss, and decaying plant material. In St. Petersburg, Leningrad Oblast, and north-western Russia, it typically fruits in spring and early summer, often in coniferous and mixed forests. The fungus has a dark brown to black exterior and a pale interior, with a diameter of 1-4 cm. It is considered a rare species in the region, but can be found in areas with rich soil and abundant organic matter.

Russia, May 11, 2021Unnamed Road, Leningradskaya oblast', Russia, 188695Observations of Pseudoplectania nigrella in Leningrad Oblast and north-western Russia show that the fungus grows in various environments, including spruce forests, moss, and roadside areas. In Pavlovsk Park, it was found on Angliyskaya Alley, in moss, and on roadside soil. Similarly, in a forest between Lembolovo and Orekhovo, it grew on roadside mossy soil, under spruce trees, and among spruce needles. The fungus formed dense clusters, colonies, and large groups, indicating its ability to thrive in these areas. It was also found on sandy soil covered by spruce needles, often accompanied by moss and lichen. The observations were made in May 2017 and 2021, suggesting that the fungus is active during this time period in the region. Overall, Pseudoplectania nigrella appears to be widely distributed and adaptable in Leningrad Oblast and north-western Russia.
