Gloeophyllum odoratum is a brown-rot fungus that grows on coniferous wood. In St. Petersburg, Leningrad Oblast, and north-western Russia, it has been found to commonly occur on spruce and pine trees, particularly in urban areas and forests with high levels of humidity. The fungus produces distinctive yellow to orange-brown fruiting bodies with a strong, sweet odor, often growing in large clusters on decaying wood. It is a saprotrophic species, playing a role in decomposing organic matter and recycling nutrients in the region's ecosystems.
