Why is the fly agaric also called the toadstool? How does the oyster mushroom manage to catch threadworms? And what does the ink cap have to do with ink? These are just a few of the questions that "The Little Mushroom Book" answers in 30 portraits. The kingdom of fungi is full of surprises, as the fruiting bodies commonly referred to as mushrooms represent only a fraction of the entire organism. Catrin Cohnen takes us into the fascinating world of fungi with their diversity and shows their significance for humans: as food and medicine, but also as poison and destroyer. She also shares the cultural and historical backgrounds, including legends and fairy tales in which mushrooms play a role. Lovingly detailed watercolors by Diana Lawniczak illustrate the volume.
