Coniophora puteana is a brown-rot fungus that decomposes cellulose and hemicellulose in wood. In St. Petersburg, Leningrad Oblast, and north-western Russia, it has been found to thrive in moist environments, such as old buildings, wooden constructions, and forest areas with high humidity. The fungus is commonly isolated from decaying timber, particularly spruce and pine, and is known to cause significant damage to wood structures. It grows optimally at temperatures between 15-25°C and relative humidity above 80%. Coniophora puteana has been identified as a dominant species in the mycobiota of wooden buildings in the region, highlighting its importance in wood decay processes.

Cellar fungus (Coniophora puteana) on a dead spruce in lower Sergievka Park. Old Peterhof, west from Saint Petersburg, Russia, October 5, 2017Kurortnaya Ulitsa, Petergof, Sankt-Peterburg, Russia, 198504Observations of Coniophora puteana in Leningrad Oblast and north-western Russia show that the fungus is commonly found on rotten logs and broken trees, particularly spruce. It was observed in various locations near Saint Petersburg, including Lisiy Nos, Kuzmolovo, Dibuny, and Old Peterhof. The fungus was identified as causing brown rot or wet rot on its hosts. In some cases, it was found to be associated with a gall-forming mycoparasite, Nodulisporium cecidiogenes. The observations were made over a period of several months, from April to October 2017, suggesting that the fungus is active throughout the growing season in this region. The fungus was often found on dead or decaying wood, indicating its role as a decomposer in these ecosystems. Its presence was documented through photographs and field notes.
