1, look at the color

When mulberry yellow is picked, the front color is bright yellow. After drying, the color will become dark yellow or brown. The whole yellow face is like satin, and different colors will appear on the yellow face from different angles. The Phnom Penh of Phellinus linteus, which is short in years and small in size, is obviously thick. With the increase of growth years, there will be less and less Phnom Penh.

2. Look at the shape

The shape of mulberry Phellinus linteus is not fixed, mostly semi-circular or other irregular. The identification mainly depends on the back texture, and there are obvious horizontal rings on the back, and the interval between rings is obvious. If the age is long, the back will crack and there will be nail-sized cracks. The more rings, the longer the years of Phellinus igniarius.

Color of wild mulberry Phellinus linteus after cutting

The front of wild mulberry Phellinus igniarius is brown, with clear tree texture, hard texture and high density, and the back is delicate yellow. Generally, the yellow surface is the same brown, which will be particularly yellow in the sun.

The authentic wild mulberry Phellinus linteus is dark brown after being cut, and it is not said that there are yellow hyphae and yellow edges overflowing, but all of them are yellow hyphae after being cut. It is a lie that merchants selling poplar Phellinus linteus deliberately deceive people in order to make huge profits. At present, the most fake mulberry yellow on the market are poplar yellow and Martin fragrant yellow, because these two kinds are closest to mulberry yellow in appearance.
