The fungus soaked for a long time and then sun-dried can eat, as long as the fungus is not moldy, sun-dried and then soaked can be eaten. But the fungus soak for a long time, easy to have bacterial growth, and easy to have the possibility of mold, at the same time, due to the long soak after the fungus in some nutrients will lose some, thus affecting the taste. So it is recommended to soak in moderation, and the time should not be too long.
