If the edible condition is only that the mushroom umbrella is partially black rather than moldy, because Tricholoma is a white wild mushroom, the surface is white, and the inside is also white after cutting, so it generally does not turn black, and blackening is only the oxidation of polyphenol oxidase in Tricholoma.
In the case of inedible, if the meat inside turns black, it can't be eaten, because the shelf life of mushroom foods such as Tricholoma is generally not long, and it will turn black after one day. After a long time, it will breed bacteria and lead to deterioration. After eating, it will cause abdominal pain, diarrhea and other discomfort.
