Ganoderma lucidum, commonly known as old cow liver, is a globally distributed scaffold fungus. The spore body of this fungus can reach up to 30-40 centimeters (12-16 inches), with a hard texture and woody texture. At the beginning of growth, it appears white, but soon turns deep reddish brown. It grows in the form of mycelium in both live and dead trees. Ganoderma lucidum can grow individually, sporadically, or in groups. Its fruiting body has a diameter of up to 3-30 centimeters, a length of 5-50 centimeters, a thickness of 1-10 centimeters, a hard texture like leather, and a woody texture. The upper surface of the fruiting body is covered with reddish brown conidia.

Agaricus bisporus is a fungus belonging to the mushroom family and genus, also known as mushroom, foreign mushroom, etc. The fruiting body of Agaricus bisporus is medium-sized, with a cap width of 5-12 centimeters. It is initially semi spherical, later flattened, smooth, slightly dry with a gradual yellow color, and the edges are initially curled inward. Mushroom flesh is brown, thick, slightly reddish after injury, with a unique mushroom aroma. The gills are initially pink, then brown to black brown, dense, narrow, free, unequal in length, with a stem length of 4.5-9 cm and a thickness of 1.5-3.5 cm. They are brown, smooth, silky, nearly cylindrical, soft or medium solid inside, with a single-layer, white, membranous ring in the middle of the stem, and easy to fall off.

This species is a large mushroom widely distributed in southern China, commonly found in fields, grasslands, flower pots, or other areas. Its prominent feature is the green color of its mature gills and spore prints. The main feature is a large body size, white cap, and brown flake scales; The surface of the stem is smooth and often has developed fungal rings. The flesh at the base of the stem turns reddish brown after injury; Fungal folds are detached, white in childhood and lead green in old age. This toxic substance has caused widespread poisoning cases in southern China. It appears harmless to humans and animals, with a morphology similar to that of an edible species. It is widely distributed, likes to grow in large groups, and has a good taste, among other factors, making it one of the most commonly ingested poisonous mushrooms.

Sulfur bacteria, also known as sulfur porous bacteria or sulfur colored porous bacteria, are a type of fungus. In the early stage, it is tumor like, resembling a brain marrow, with a tile shaped arrangement of fungal caps, and the meat is tender and crispy after sweating. The cap is 8-30cm wide and 1-2cm thick, with a sulfur colored to bright orange surface, fine or no fluff, wrinkles, no ring, thin and sharp edges, wavy to lobed. Mushroom meat is white or light yellow in color, with sulfur colored pores that fade after drying. The pores are polygonal, with an average of 3-4 pores per millimeter. Spores are oval shaped, nearly spherical, smooth, colorless, 4.5-7 × 4-5 μ m. The important feature of this bacterium is the tile shaped arrangement of fruiting bodies, which are sulfur colored. Eating it during childhood has a better taste.
