Extract from Wikipedia article: Perenniporia subacida is a species of poroid fungus in the family Polyporaceae. It is a plant pathogen that infects Douglas firs. The fungus was originally described in 1885 by American mycologist Charles Horton Peck. Marinus Anton Donk transferred it to the genus Perenniporia in 1967. The four varieties of this fungus originally proposed by Peck, namely Polyporus subacidus var. stalactiticus, P. subacidus var. tenuis, P. subacidus var. tuberculosus and P. subacidus var. vesiculosus, have been shown to be synonyms. The species is inedible.
Perenniporia subacida is a rare polypore fungus found in northern Europe, including north-western Russia. In St. Petersburg and Leningrad Oblast, it grows on deciduous trees, particularly on oak, beech, and birch. The fungus has been recorded in urban parks and forests, where it fruits from July to October, producing resupinate to effused-reflexed basidiocarps with a sour or acidic smell.

Pores of resupinate polypore fungus Perenniporia subacida(?) on a cut surface of a tree in Lindulovskaya Larch Grove, near Roshchino, 30 miles north-west from Saint Petersburg. Russia, September 4, 2018Unnamed Road, Leningradskaya oblast', RussiaIn Leningrad Oblast and north-western Russia, Perenniporia subacida was observed growing on cut surfaces of trees. Specifically, in Lindulovskaya Larch Grove near Roshchino, approximately 30 miles north-west of Saint Petersburg, the fungus was found on a tree cut surface. The observations were made on September 4, 2018. The fungus appeared as a resupinate polypore mushroom, with visible pores on its surface. The pores of the fungus were also observed in detail, providing insight into its morphology. These observations suggest that Perenniporia subacida is able to grow on freshly cut wood in this region, potentially playing a role in decomposing organic matter. Further study would be necessary to fully understand its ecological significance in this area. The specific location and timing of the observations provide valuable context for understanding the habits of this fungus species.
