The overall requirements for the shape of china Dried shiitake mushrooms are that the cap is thick and neat, the cap surface is smooth, and the size is uniform; the gills are neat and dense; the edges are curled and thick; Crumbs and flakes. Compared with picking fresh shiitake mushrooms, choosing dried shiitake mushrooms needs to be more careful. The selection of dried shiitake mushrooms mainly depends on the "face", which is the cap of the shiitake mushrooms. The thicker the mushroom cap, the more intense the fragrance; the edge of the mushroom cap should be rolled inward, if it is straight, it means it is overcooked. In addition, China Dried shiitake mushrooms can be divided into flower mushrooms, thick mushrooms, thin mushrooms and diced mushrooms in appearance.

Flower mushroom: China Dried shiitake mushrooms have cracked patterns on the cap and are called flower mushrooms. The cracked patterns indicate that more nutrients are accumulated, and the content of protein, amino acids and minerals is high. Therefore, the nutritional value of mushrooms is higher, and the organization is tight, the flavor is strong, and the taste is smooth and tender. The "Tianbaihua mushroom" with white and tender flesh exposed in the crack is the best among them. It should be noted that the patterns on the mushroom caps should be natural, large and small, deep and shallow. Otherwise, it is likely that the common shiitake mushrooms were artificially scratched.

Thick mushroom: "Face collapsed and tight", the flesh is thick, the cap has no pattern, chestnut and slightly shiny; the flesh is dense, the taste is smooth, and the fragrance is strong. Thick mushrooms are 4-6 cm in size, with flat steamed buns or gong-shaped rolls on the edges, and small and few wrinkles are the best products.

Thin mushrooms: China Dried shiitake mushrooms have thinner flesh and are produced in late autumn. The aroma and taste are not as good as those of flower mushrooms and thick mushrooms. When purchasing, it is better to choose the umbrella with less opening and less damage.

Mushroom Ding: It is the "Japanese mushroom" and "Qingming mushroom" mentioned in ancient books. It is the first small shiitake mushroom to sprout during the Qingming Festival. Although it is small, its quality is not bad at all, and it is the most economical. The principle of choosing diced mushrooms is "tenderness", the more tender the more fragrant and smooth.
