I took microbiology in college and we totally did NOT do this...the scientists in the mycology lab at the J. Craig Venter Institute sure decided to spice up their lab with a little holiday art by growing fungus. Their website showed three photos of holiday fungus art: a green Christmas tree, a snow man, and a white Christmas tree. See below and hover over the rest of the images for the names of the fungi used to grow into these funky holiday forms!
