Of course. This is a normal phenomenon. When Mabo matures, the inside will turn black. Puffball has an outer layer and an inner layer. When I was young, it was white inside and outside, delicious and edible. It can be cooked, tender as tofu, and turns grayish brown when cooked. With a flick of your finger, the dust flies out and the inside is like a sponge. The taste has changed, but it can also be eaten.
Generally, puffball fungus grows in the underground litter layer and likes high temperature and high humidity environment, so it usually appears in July and August with abundant rainfall and is only suitable for living in mountainous areas or semi-mountainous areas with good ecological environment. The fruiting bodies of this objective fungus are generally nearly spherical or pear-shaped, with diameters ranging from a few millimeters to 1 m or more. Usually sessile, sometimes with a false handle.
