Extract from Wikipedia article: Punctularia strigosozonata is a fungus species of the genus Punctularia. It was originally described in 1832 by Lewis David de Schweinitz as a member of genus Merulius. Patrick Talbot transferred it to genus Punctularia in 1958. Punctularia strigosozonata produces the antibiotic phlebiarubrone.
Punctularia strigosozonata is a species of crust fungus that grows on dead wood. In St. Petersburg, Leningrad Oblast, and north-western Russia, it has been found to typically occur on deciduous trees, particularly birch and alder, in moist environments such as forests and riverbanks. The fungus produces resupinate fruiting bodies with a smooth to tuberculate hymenial surface and a white to cream-colored margin. It is a relatively rare species in the region, but can be locally common in areas with abundant suitable substrate.

Russia, August 10, 2024Russia, Leningrad, Семрино, 188345, 41к-222Observations of the fungus Punctularia strigosozonata in Leningrad Oblast and north-western Russia reveal its presence on fallen aspen trees. On May 7, 2021, the fungus was found on a fallen aspen near Saint Petersburg, with hairy caps of mushrooms visible. A close-up examination showed the distinctive features of Punctularia strigosozonata. Two weeks later, on May 21, 2021, the fungus was again observed on a fallen aspen in the same area. Additionally, on August 10, 2024, the fungus was found on a log in a forest near Semrino, south of Saint Petersburg. The observations suggest that Punctularia strigosozonata is a common white-rot fungus in the region, growing on deciduous tree substrates. The sightings were recorded over a period of three years, indicating the fungus's persistence in the area. The fungus's habitat appears to be restricted to fallen trees and logs.
