Junghuhnia pseudozilingiana is a rare polypore fungus. In St. Petersburg and Leningrad Oblast, it has been found growing on decaying wood, particularly coniferous tree stumps and logs. In north-western Russia, the species has been recorded in various forest habitats, including spruce and pine forests, often associated with moss-covered substrates. Fruit bodies are annual, resupinate to effused-reflexed, with a greyish-brown to brown crust and white to yellowish pores. The fungus is considered a saprotroph, contributing to wood decomposition in these ecosystems.
