C. gattii (image) Duke University Share Print E-Mail Caption This false-color electron microscope image catches the fungus Cryptococcus gattii in the act of producing its infectious spores. The club-shaped blue structure is a reproductive organ called the basidium, which projects off the fungus body like an apple off a tree. The spores are colored yellow, and are like seeds that can give rise to a new organism.
