[0002] Edible fungi are large, edible fungi (commonly known as mushrooms). There are over 350 known species of edible fungi in China, most of which belong to the subphylum Basidiomycota. Common edible fungi include shiitake mushrooms, straw mushrooms, button mushrooms, wood ear mushrooms, white fungus, hericium erinaceus, bamboo fungus, matsutake mushrooms, button mushrooms, red mushrooms, ganoderma lucidum, cordyceps, truffles, white mushrooms, and boletus. A few belong to the subphylum Ascomycota, including morels, saddle mushrooms, and truffles. These fungi thrive in different regions and ecological environments.
