1, identified by shape
The shape of wild Phellinus igniarius is mostly semi-circular, and the texture on the back is obvious, which is a circle of horizontal annual rings with large annual ring spacing. Old Phellinus linteus' back will crack and have fingernail-sized lobes. Wild Phellinus igniarius is generally older with obvious annual rings.
Step 2 distinguish by color
When the wild Phellinus igniarius was just picked from mulberry trees, its color was bright yellow. After drying, it will turn dark yellow and brown, and the edge of Phellinus linteus will also have a golden edge. However, the older Phellinus igniarius, the less the number of Phnom Penh, the less obvious it is.
Step 3 tell by taste
Wild Phellinus igniarius has a faint fragrance when it is not dried, and completely dried Phellinus igniarius has no taste. Only by cooking dried Phellinus linteus in water will it give off the same smell as mushrooms. Phellinus linteus water will not be bitter or sour, and it will be sweet after careful tasting.
Step 4 distinguish by size
The size of wild Phellinus igniarius will not exceed the size of the palm, generally only 5 ~ 20cm long, which can be judged by fingers. The whole Phellinus igniarius is thick, with rough front and scales falling off, but the wild Phellinus igniarius has smooth and bright edges and does not absorb water like a sponge.
Brief introduction of Phellinus igniarius
Phellinus linteus is a perennial fungal substance, which is the fruiting body of Phellinus linteus, a fungus of Polyporaceae, and is used as medicine. The fruiting body is what we call a leaflike body, woody, mostly hemispherical or other irregular shapes. The back of the bacteria is black or black-yellow, with obvious horizontal rings. After a long time, the back will crack, the belly will be brown or yellow, and the edge will be yellow.
