It belongs to a large fungus with a cylindrical cap. Within 40 minutes after opening the umbrella, the marginal fungus folds dissolve into ink-like liquid, and the stalk becomes slender. The cap is 3 ~ 5 cm in diameter, 9 ~11cm in height, and the surface is brown to light brown, which breaks into larger scales with the growth of the cap. Mushroom meat is white. The stipe is white, cylindrical, slender, and gradually thickens downward, 7 ~ 25 cm long,1~ 2 cm thick and smooth.

Distributed in temperate and subtropical humid areas. After rain, it will grow rapidly, mostly in grassland and forest ground, and even grow on the roof in rainy season. This mushroom is generally edible. But it contains gastrointestinal tract irritants such as carbolic acid, and also contains many alkaloids such as adenine, choline, spermine, tyramine and tryptamine, as well as sterols. It may cause poisoning after eating, and it is easy to cause poisoning when eating with alcohol such as beer.

So I suggest not to eat it. After all, we don't eat it very often. This mushroom is often found in my hometown, but the old people in my hometown didn't want to eat it. .
