Weathering of wood and soil nutrients make it a fertile place for fungus to grow. What you see is the embodiment of a combination of soil and wood decay that provides nutrients for this fungus. The shape is very small, about the size of the tip of a child's little finger. I found it among the bushes. I looked for information about the mushroom, many said that the mushroom should not be consumed. The construction of the mushroom is almost similar to a hard turtle shell, but this is a mushroom, not a baby turtle. Some sources that I found say that the scientific name of this mushroom is boletus .
