1. Auricularia auricula fruiting bodies are clustered and often overlap with tiles. Spike leaflike or nearly forest-like, with wavy edges, thin, 2-6cm wide, the largest reaching 12cm, and about 2mm thick, with short lateral stalks or narrow base, fixed on the substrate. At first, it was soft colloid, sticky and elastic, and then it was slight cartilage. After drying, it shrinks strongly and turns into black hard and brittle keratin, almost like leather. The back is curved outside, purple-brown to dark blue-gray, with sparse short fluff. The villi are brown at the base, gradually tapering upward, almost colorless at the top, (115-135) μ m× (5-6) μ m, with concave inside, smooth or slightly veined, and dark brown to brown. Mushroom meat is formed by locking hyphae, with a thickness of about 2-3.5 μ m, in which the seed layer is born and consists of basidiomycetes, basidiospores and lateral filaments. The basidium is 60-70μm long and about 6μm thick, with obvious diaphragm. Spore kidney
Shape, colorless, (9- 15) μ m× (4-7) μ m; Conidia are nearly spherical to ovoid, (115) μ m× (4-7) μ m, colorless and often appear on the surface of seed layer.
2. The fruiting body of Auricularia polytricha was cup-shaped at the beginning, and gradually changed into spike-shaped to leaf-shaped, gelatinous and tough. After drying, the bone was soft, mostly smooth, and the base was often wrinkled, with a diameter of 10- 15cm, and it shrank strongly after drying. The sterile surface is grayish brown to reddish brown with fluff, (500-600)μm×(4.5-6.5) μ m, colorless, and only the base is brown. The seed layer is purple-brown to nearly black, smooth and slightly wrinkled, with white powder or spores on it when it matures. The spores are colorless, kidney-shaped, (13- 18) μ m× (5-6) μ m. ..
3. The dried fruiting bodies of Auricularia auricula are in a string, gelatinous and cartilaginous shape. Cup-shaped in childhood, discoid to leaflike in later stage, (2-7)cm ×( 1-4)cm, 5- 10mm thick, with flat or wavy edges. The subsoil layer is depressed, with a thickness of 85- 100μm, obvious folds and grid formation. The infertile face is milky yellow to reddish brown, smooth, and the fluff is sparse and colorless; Villi (35-185) μ m× (4.5-9) μ m. The spores are cylindrical, slightly curved, colorless and smooth, and (10- 13) μ m× (5-5.5) μ m. ..
