Synonym: Calicium polyporaeum.
Common name: fairy pins.
Russian name: Feokalitsium poliporovyy.
Phaeocalicium polyporaeum is a fungus that grows on the fruiting bodies of other fungi, particularly polypores. In St. Petersburg and Leningrad Oblast, it has been found on various substrates, including dead wood and stumps. In north-western Russia, it is considered a rare species, typically occurring in old-growth forests with rich fungal diversity. Records from the region show that Phaeocalicium polyporaeum often infects species of Fomitopsis, Ganoderma, and Trametes, with fruiting bodies appearing in summer and autumn.
Old purple toothed polypore mushrooms (Trichaptum biforme) with algae and tiny black Fairy Pins fungus (polypore club lichen, Phaeocalicium polyporaeum) on its surface on a fallen birch in Sosnovka Park. Saint Petersburg, Russia, March 20, 2017
Unnamed Road, Sankt-Peterburg, RussiaIn Leningrad Oblast and north-western Russia, observations of Phaeocalicium polyporaeum have been made on various substrates, including old purple toothed polypore mushrooms (Trichaptum biforme). The fungus was found growing on the surface of fallen birch trees, particularly in Sosnovka Park, Saint Petersburg. On March 20, 2017, a notable observation was made where Phaeocalicium polyporaeum was present alongside algae and other microorganisms on the surface of Trichaptum biforme. The fungus formed tiny black structures, characteristic of its species. This observation highlights the presence of Phaeocalicium polyporaeum in the region, often associated with specific hosts like Trichaptum biforme, and demonstrates its ability to coexist with other organisms on decaying wood. Further observations are necessary to fully understand the distribution and ecological role of Phaeocalicium polyporaeum in this region. The fungus's presence can indicate a specific stage of decomposition.
