My hometown is Suiyang Town, Dongning County, Heilongjiang Province, which is the hometown of black fungus. I love the streams, rivers, and mountains in my hometown, but I love the black fungus in my hometown even more. My hometown invested 10 million yuan on July 3, 2002 to build the now famous black fungus wholesale trading market at home and abroad. Its completion has guaranteed income for our households in Suiyang Town and surrounding towns. Jiang Runhao, vice president of the National Edible Fungi Association, came to Suiyang Town for inspection and wrote the words "Dongning black fungus, the first in China". In just one year, our town has become the largest black fungus distribution center in the country. The scientific name of black fungus is Auricularia auricula (L. EXHook) Underw, also known as fungus, light fungus, and cloud fungus. It belongs to the fungus Basidiomycetes, Tremella order, Agaricaceae, and Auricularia genus. In the genus Agaric, the main species are Auricularia auricula, Black Wrinkle Agaric, Agaric agarica, Brown Agaric, Hairy Agaric and Light Agaric. Black fungus is a large fungus composed of mycelium and fruiting bodies. Mycelium is the vegetative organ of black fungus, equivalent to the roots, stems, and leaves of higher green plants, and is the main body of black fungus. Mycelium is composed of many five-color transparent, tubular hyphae with transverse septa and branches. It can absorb water, inorganic and organic nutrients from the matrix for the growth and development needs of black fungus, and produce reproductive organs - fruiting bodies at a certain development stage. Black fungus is famous for its crispiness and is an indispensable condiment in Chinese recipes. It is also a nutritious food and contains a variety of vitamins (carotene, vitamin B1, vitamin B2, and nicotinic acid).
