Mystery liverwort fungus, chapter two

Part 2 in FAM’s series on the mysterious liverwort fungus. What the heck is this? Mycology is hard.

Cabbage monstrosities

The things that were once called Fungi but aren’t anymore are legion. Here’s one of them, a little swimmy thing that causes clubroot of cabbage. It gives cabbage monstrously clubbed roots, and as a bonus, acts as a vector for other diseases. Although we love its monstrous cruelty, we have banished it from the kingdom of Fungi. Be gone!


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.
