Coriolus versicolor is distributed all over the country, mostly on dead standing trees, fallen trees, dead branches and aging living trees of various broad-leaved trees, and occasionally on decaying trees of coniferous trees such as larch and black pine.
Medicinal characteristics of Coriolus versicolor
The cap is fan-shaped, semi-circular or shell-shaped. Constantly overlapping to form shingles or rosettes, with a diameter of 1- 10cm and a thickness of 1-4 mm, and the surface is densely covered with fluff (hyphae) of gray, brown, blue, purple, black and other colors, forming a multi-color narrow concentric ring belt with thin edges, grayish brown, yellowish brown or yellowish ventral surface, and sterile tubes. The bacteria tube is single-layer, 0.5-2mm long, mostly light brown, with nearly round to polygonal nozzle, with 3-5 tubes per1mm. A slight breath, a faint taste.
Coriolus versicolor identification
Microscopic identification
Longitudinal section of Coriolus versicolor: the outer side of the shell is a villous layer with different lengths and no branches; The hyphae of the shell are closely arranged, and there are many pigment particles in the hyphae cavity. The pulp layer of auricularia auricula is thick and colorless, and the hyphae are closely arranged. The bottom is the bacterial tube layer, and the bacterial tubes are arranged neatly.
The powder is light yellow. Spores are oval, 5-7 μm long and 2-3 μm in diameter. They have two walls, the outer wall is smooth and colorless, the inner wall is light brown, and there are four kinds of hyphae. The villous hyphae are colorless, single or several connected, unbranched, 3-5um in diameter, and there are many granular substances in the hyphae wall. The mycelium of skeleton is thick, 5-7um in diameter, unbranched and flat and colorless. The wall of reproductive hyphae is extremely thin and transparent, with a diameter of 3-4um, unbranched and straight. The entangled hyphae are thin, with a diameter of 65438±0.5-4um, and often bend.
Chemical identification
Take 2g of Coriolus versicolor coarse powder, add 20ml of water, heat in water bath for 65438 00 minutes, filter, take 2ml of filtrate, add 4-5 drops of basic copper tartrate test solution, and heat in water bath for 5 minutes to produce red precipitate.
