Lemon lapse time rot

Moldy lemons aren’t victims of just any mold–they have their own specific pair of evil parasites. Here a lemon succumbs to one of those evil Penicillium twins, in time lapse.

Hemlock Rust

Complementary Colors–Hemlock rust

Poplar and hemlock can together support a happy population of rust fungi. Either one alone? No rust. Rusts are weird.


Most people don't pay much attention to fungi, which include things like mushrooms, molds, yeasts, and mildews. Here at Cornell we think they're pretty fascinating. In fact, even the most disgusting foot diseases and moldy strawberries are dear to our hearts. We'd like to talk to you about fungi, so that like us, you too can tell gross stories at the dinner table. Afterwards, maybe you'll notice some things you would have overlooked before, and we think this could be good for the planet.
