Corticioid mushrooms Phellinidium ferrugineofuscum on a bark of a dry spruce tree near Lisiy Nos. West from Saint Petersburg, Russia, August 23, 2017Polyanskaya Doroga, Sankt-Peterburg, Russia, 197755Observations of Phellinidium ferrugineofuscum in Leningrad Oblast and north-western Russia reveal its growth patterns on spruce trees. On February 18, 2017, a crust of the fungus was found on a spruce near Lisiy Nos, west of Saint Petersburg. Later, on August 23, 2017, poroid and corticioid forms of the mushroom were observed on the bark of a dry spruce tree in the same area. The poroid form had a distinct pore-like structure, while the corticioid form had a smooth, crust-like appearance. These observations suggest that Phellinidium ferrugineofuscum can thrive on dead or dying spruce trees in the region, and can exhibit different growth forms depending on the environment. The fungus was found to be present in the area during both winter and summer months, indicating its adaptability to different seasonal conditions.
