There are also beliefs that such stone mushrooms provided fertility for the soil and people. Therefore, in some places, the worship of these idols persisted for centuries until the end of the 20th century (and even after being transferred to a museum, elements of the rituals are still performed). The dating of stone mushrooms is approximate; they date back to about 1000 AD. These stone mushroom idols are very similar to two Slavic stone idols from northeast lands: Sheksna idol (in Novgorod museum, Novgorod region, Russia) and Sebej idol (Sebej museum, Pskov region, Russia). These Slavic idols have a face and a phallic shape. Their characteristic feature is a hat.
