Radiation-loving fungi: the perfect space food?

http://space.newscientist.com/article/dn11917-radiationloving-fungi-the-perfect-space-food.html

It is mainly saying that a radioactive mushroom grows more and being edible in space it will help the space travelers on extended mission by them being able to have more food. It also explains what will happen if they added more melanin to one mushroom and left one mushroom alone to grow and just zapped them both with gamma rays. As expected the dark colored melanin filled one grew more. Arturo Casadeval thinks that fungi will be able to live in the worst conditions as long as their is radiation. The dark colored fungi uses the pigment that also makes our skin dark, melanin.
1) What type of lifestyle does the fungus in the article have? (Is it saprophytic, autotrophic, or parasitic?) What information lead you to this conclusion?
It is autotrophic and saprophytic. This lead me to these conclusions because if is absorbs radiation which is just another form of sunlight then it's autotrophic. It is saprophytic because it can still absorb dead materials and it loves moist dark places.

2) What benefits or problems can you foresee with this particular fungus?
It will become to radioactive and probably cause harm to the people trying to eat or touch it.

3) List three things you learned from this article in your own words.
I learned that there really is such a thing a a radioactive mushroom. I also learned that they could probably grow on just radiation. I also learned that it could help astronauts in outer space by them having extra food.

4) Infer what potential impact this fungus will have on the environment it grows in.
It probably will cause other things to become radioactive and may cause things to grow larger or die. People may become radioactive and dying might occur of the human race or not.
