Toxic Deformed Mushrooms Found During Ukrainian Mushroom Foraging Season

Ukrainian mushroom foragers participating in the autumn peak of the “quiet hunt” have encountered deformed porcini mushrooms infected with a parasitic fungus that produces dangerous toxins, according to reports from unian.net. September and October mark the height of the mushroom season in Ukraine, driving both experienced collectors and amateurs into local forests while sparking advice-sharing in online communities such as the popular Facebook group “Sēnes.”

Parasitic Fungus Makes Porcini Mushrooms Unsafe to Eat

Recent social media posts in the “Sēnes” Facebook group featured photographs of asymmetrical and irregularly shaped porcini mushrooms, prompting questions about whether the specimens remained safe to eat, unian.net reported. Experienced foragers in the comments identified the specimens as ordinary porcini affected by the parasitic fungus Hypomyces. According to experts within the Facebook group, the infection destroys the internal tissues of the mushroom and causes severe physical deformation.

Separately, a resident of the Volyn region discovered 10 giant mushrooms, with one individual specimen weighing more than one kilogram—the largest she had ever found.
