**4. Global mushroom cultivation prospects**

These Mushrooms have long been used in traditional medicine in China, Africa, the Middle East, and Japan particular. Edible mushrooms could only be found in nature and were hard to farm and sustain Wild forest collection is still popular across the world, especially in southern Asia [43, 44] and in developing nations [45]. Auricularia, Flammulina, and Lentinula are examples of mushrooms. Have been most probably initially farmed in China and other Emerging nations around the year 600–800 AD [46]. Pure mushroom cultures were first created from spores and tissue towards the turn of the twentieth century when they were first grown on a wide scale. The quantity of wild mushrooms is decreasing as a result of both degraded surroundings and natural resources, as well as more expensive labor, produced mushrooms provide more food items which decrease food insecurities, they also provide more affordable and healthier meals [47]. With the global population expanding and acreage per capita shrinking, fast industrial development, global warming, and a desire for excellent and functional foods, secondary agriculture and novel crops like mushrooms will be necessary. Mushroom farming might potentially play a significant role in sustainable agriculture and forestry. Agriculture, forestry, and food processing create massive amounts of a diverse range of organic waste. The mushroom industry has a major and extensive influence on livelihoods and reducing poverty. There have been hundreds of discovered fungus species that have made major contributions to human diet and medicine.

Gupta et al., there are now 110,000 species of fungus [48], 16,000 (15%) of which are mushrooms [48, 49]. There are around 3000 types of edible mushrooms from 231 genera [14, 49, 50], with only approximately 200 experimentally grown, In various countries, 100 are economically farmed, 60 are commercially cultivated, and more than ten are

produced industrially. Around 700 of the known 16,000 mushroom species are regarded harmless and have medicinal properties [49]. The inclusion of fresh varieties of mushroom farming for commercial purposes has resulted in a fast expansion of the worldwide mushroom business during the last two decades. Furthermore, mushroom cultivation and development have had a favorable influence in terms of economic growth worldwide, the influence of mushroom farming, mushroom derivatives, and mushroom foodstuffs on human well-being in the twenty-first decade may be termed as a "nongreen revolution."
