Victor Pelevin’s novel Generation P has attracted both popular and academic interest for its ability to capture the zeitgeist of Russia in the 1990s and a generation searching for a new identity in the ruins of the Soviet Union. However, one element has been largely ignored by scholars: the role of fungi and, specifically, the entheogenic mukhomor. Here we discuss the history of mukhomor in the Russian context and demonstrate how Pelevin’s representations of mukhomor advance the novel’s critique regarding the reinvention of Russia’s identity after the fall of the Soviet Union. We argue that via its mukhomor-induced hallucinations, the novel ironizes the imperial narratives which sought to restore a mythical but allegedly authentic Russian past. The novel plays with the idea that if there is a future that can qualify as authentically Russian, then it should be one where the very notion of Russianness is abandoned. What renders this future authentically Russian is the genetic origin of mukhomor in the Russian hinterland, the very element which enables a vision of the world as such, devoid of symbolic order and of all identities.
