It's kind of a suprising to me that it was a fungus and not a plant that developed this ability. After all, plants already feed on elecromagnetic radiation.
The chlorophyll in plants is finely tuned to absorb specific wavelengths of light. It already has a hard time with green light compared to blue light, and it's simply not going to work at all with radiation that has wavelengths that are orders of magnitude shorter. Chlorophyll acts like a little antenna that gets excited by certain light frequencies, but ionizing radiation would just blow the chlorophyll molecules apart and destroy them.
Taking advantage ionizing radiation is going to require a completely different mechanism than plant photosynthesis, just like you can't use glass lenses or parabolic mirrors to focus X rays or gamma rays. Plants probably have no more chance of having such a mechanism than fungi do.
