Extract from Wikipedia article: Ascocoryne sarcoides is a species of fungus in the family Helotiaceae. The species name is derived from the Greek sarkodes (fleshy). Formerly known as Coryne sarcoides, its taxonomical history has been complicated by the fact that it may adopt both sexual and asexual forms. Colloquially known as jelly drops or the purple jellydisc, this common fungus appears as a gelatinous mass of pinkish or purple-colored discs. Distributed widely in North America, Europe and Asia, A. sarcoides is a saprobic fungus and grows in clusters on the trunks and branches of a variety of dead woods. Field studies suggest that colonization by A. sarcoides of the heartwood of black spruce confers some resistance to further infection by rot-causing fungi. A. sarcoides contains the antibiotic compound ascocorynin, shown in the laboratory to inhibit the growth of several Gram-positive bacteria.
Ascocoryne sarcoides is a species of fungus that belongs to the family Helotiaceae. It is characterized by its pinkish to orange-colored apothecia and white to cream-colored flesh. In St. Petersburg, Leningrad Oblast, and north-western Russia, Ascocoryne sarcoides has been found growing on decaying wood, particularly on coniferous trees such as spruce and fir, in moist and shaded areas, often near water bodies or in swampy terrain. The fungus typically fruits in late summer to early fall, with a peak in August and September. It is considered a relatively rare species in the region, but can be locally abundant in suitable habitats.

Saint Petersburg, Russia, September 23, 2017Ulitsa Zhaka Dyuklo, 67, Sankt-Peterburg, Russia, 194214Observations of Ascocoryne sarcoides in Leningrad Oblast and north-western Russia show that the fungus grows in various locations, including Sosnovka Park and Dubki Park in Sestroretsk. It was found on rotten timber, cut trees, stumps, and upper surfaces of stumps. The fungus was observed in different stages, including cup stage, and exhibited a purple color. Multiple sightings were recorded in 2016, specifically on August 25 and October 2, and in 2017, on September 13 and 23. The fungus seems to thrive in these areas, with repeated observations in the same locations over time. The variety of substrates and consistent appearance suggest that Ascocoryne sarcoides is a common species in this region, particularly in parks and wooded areas. The observations provide valuable insights into the habitat and growth patterns of this fungus.
