Fungi and other organisms traditionally recognized as fungi, such as oomycetes and myxomycetes slime molds , often are economically and socially important, as some cause diseases of animals such as histoplasmosis as well as plants such as Dutch elm disease and Rice blast. Apart from pathogenic fungi, many fungal species are very important in controlling the plant diseases caused by different pathogens.
For example, species of the filamentous fungal genus Trichoderma considered as one of the most important biological control agents as an alternative to chemical based products for effective crop diseases management.
Field meetings to find interesting species of fungi are known as 'forays', after the first such meeting organized by the Woolhope Naturalists' Field Club in and entitled "A foray among the funguses"[ sic ]. Some fungi can cause disease in humans and other animals - The study of pathogenic fungi that infect animals is referred to as medical mycology. It is presumed that humans started collecting mushrooms as food in prehistoric times. Mushrooms were first written about in the works of Euripides B.
The Greek philosopher Theophrastos of Eresos B. It was later Pliny the Elder 23—79 A. The word mycology comes from the Greek: The Middle Ages saw little advancement in the body of knowledge about fungi.
Rather, the invention of the printing press allowed some authors to disseminate superstitions and misconceptions about the fungi that had been perpetuated by the classical authors.
The start of the modern age of mycology begins with Pier Antonio Micheli 's publication of Nova plantarum genera. The term mycology and the complementary mycologist were first used in by M. For centuries, certain mushrooms have been documented as a folk medicine in China , Japan , and Russia. Current research focuses on mushrooms that may have hypoglycemic activity, anti- cancer activity, anti- pathogenic activity, and immune system -enhancing activity.
Recent research has found that the oyster mushroom naturally contains the cholesterol-lowering drug lovastatin , mushrooms produce large amounts of vitamin D when exposed to ultraviolet UV light ,  and that certain fungi may be a future source of taxol. From Wikipedia, the free encyclopedia. While mushrooms and toadstools poisonous mushrooms are by no means the most numerous or economically significant fungi, they are the most easily recognized.
The Latin word for mushroom , fungus plural fungi , has come to stand for the whole group. Fungi other than mushrooms are sometimes collectively called molds, although this term is better restricted to fungi of the sort represented by bread mold. For information about slime molds, which exhibit features of both the animal and the fungal worlds, see protist.
