Moldy bread is cool

There’s nothing more fascinating than watching molds grow in time lapse. Or is there? This student post describes the inner life of Rhizopus, a remarkably busy and exuberant genus of molds. It is probably eating something in your kitchen as we speak! Today we admire the magnificence of Rhizopus eating your lunch, and introduce its surprising and extraordinary sidekick.

Of Fungus and Falcons

Sometimes I think fungi in the genus Aspergillus just have more get-up-and-go than other fungi. Some are good, and sure, some are evil — you just have to admire their audacity. Turns out one particular Aspergillus is a notorious enemy of birds, and can even take down a powerful raptor like a hawk or falcon in a matter of days. Read on for more about falconry and fungi in this post by Abby Duvall.

Percy the cat

Ringworm in Cats: Percy’s Case

Old and well-loved cats get infections sometimes. Here is the story of Percy, a cat who has battled several different attackers in the last little while: two fungi, a mystery cat, a virus, and a bacterium. He even generously shared one of them with his human family. But don’t worry, they’re all OK now.

Mycena chlorophanos

This bark glows in the dark! Bioluminescence in mushrooms

The very coolest mushrooms of all are the ones that glow, don’t you think? We don’t know, yet, how they do it, but perhaps there are a few different mechanisms, because we infer that bioluminescence has arisen multiple times over the course of evolution. Why? Well, we have some ideas. These mushrooms remain mysterious though: we don’t know exactly why or how they glow, but they do glow, and that is excellent.

Paul Stamets hunting Agarikon


The fungus Fomitopsis officinalis has a long history of use in North America and elsewhere, both as medicine and as a medium of ritualistic art. Read about Agarikon and its uses, and follow Fungi Perfecti President Paul Stamets on a successful expedition to find this rare mushroom.

Sacred mushrooms

Mushrooms as Sacred Objects in North America

Although surely many Native American peoples were experts on fungi, we have little knowledge of how they used them, particularly the more ephemeral mushrooms. Here’s a primer on three different bracket fungi (conks) used by some native peoples.

Hypholoma sublateritium

Taming The Fungus

Many tasty mushrooms aren’t hard to culture, if you know the tricks. Here is our illustrated primer on making a clean tissue culture of a wild or cultivated mushroom. Later you can try to get it to fruit in your basement or backyard!

smells like maple syrup

Lactarius helvus, the maple syrup milky cap

Milky caps are distinctive mushrooms that “bleed” milk when you break them. So it’s easy to recognize the genus, Lactarius, but it’s often tricky to identify the drab ones to species. Here’s one that smells like maple syrup, or fenugreek. But although it smells like things you can eat, don’t eat it, or you’ll be sorry.

Boletus edulis

How to eat a bolete

King boletes are among the most delicious of mushrooms, so why is it that I am so bad at finding them? Some of their sisters are also delicious edibles; a few are not so good. This piece is not so much a guide to boletes, but rather an account of how to eat them.


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.
