  • Blackening podgruzdok – Compared to white-black, this is a larger mushroom. It does not have such frequent plates, and the flesh turns red, and then blackens on the cut.
  • Loader (russula) is often plate-shaped – Quite often found in our forests. It has the same frequent plates, and the flesh on the cut also changes its color from light to dark and black. But the pulp of this mushroom has an unpleasant burning taste.
  • Russula black – The pulp of this mushroom tastes good, and it also turns black when cut. The plates of this fungus are frequent, dark in color.

Such mushrooms, together with the white-black load, are included in a special group of blackening mushrooms. This is due to the characteristic behavior of the pulp on the cut, because it changes its color to black without going through the so-called brown stage. And if you act on the pulp of the fungus with ferrous sulfate, then the color changes are completely different: at first it becomes pink, and then it acquires a green tint.
