Mushrooms, in the view of modern biologists, are a separate kingdom of living nature on a par with the kingdom of plants and the kingdom of animals. That is, mushrooms are not plants, as scientists previously believed. What we are accustomed to calling a mushroom - be it a cap on a stalk, like that of a russula or boletus, a ball of a puffball or the “hoof” of a tinder fungus - is the fruiting body. The shapes of fruiting bodies are extremely diverse. There are cap mushrooms, bowl mushrooms, cup mushrooms, bush mushrooms (horned mushrooms), balls and clubs (puffballs). From this book you will learn about edible and poisonous mushrooms (and how to distinguish them), as well as those that simply interesting for their unusual appearance. A textbook for primary and secondary school students.
