"...here's the really funky thing about C. sphaerospermum: Although scientists have shown that the fungus flourishes in the presence of ionizing radiation, no one has been able to pin down how or why. Radiosynthesis is a theory, one that's difficult to prove.
The mystery began back in the late 1990s, when a team led by microbiologist Nelli Zhdanova of the Ukrainian National Academy of Sciences embarked on a field survey in the Chernobyl Exclusion Zone to find out what life, if any, could be found in the shelter surrounding the ruined reactor.
There, they were stunned to find a whole community of fungi, documenting an astonishing 37 species. Notably, these organisms tended to be dark-hued to black, rich with the pigment melanin."
