Fungus Amongus: How Mushrooms Run the World
Episode Overview:
In this insightful episode of Wildly Curious, Katy and Laura dive into the fascinating world of fungi, exploring their essential roles in our ecosystem, medicine, and more. They highlight how mushrooms aren’t just weird-looking growths in the woods, but vital organisms that shape life as we know it. From decomposition to aiding plant growth and even curing diseases, fungi are nature’s hidden powerhouse.
Expanded Key Topics
Fungi Basics:
There are over 144,000 known species of fungi, and scientists discover more every year. It’s estimated that 90% of all fungi are still unknown to science!
Five main groups of fungi: chytrid fungi, zygomycetes (bread molds), glomeromycetes (soil fungi that form symbiotic relationships with plants), ascomycetes (includes yeasts and molds like those causing athlete’s foot), and basidiomycetes (mushrooms and toadstools).
Fungi’s Role in Decomposition:
Fungi, along with bacteria, are the main decomposers in ecosystems. They break down organic matter into essential elements like carbon, oxygen, nitrogen, and phosphorus, which are then released back into the environment to nourish plants and other organisms.
Without fungi, we’d be overwhelmed with dead plants and animals, as nothing would decompose effectively.
Mycorrhiza:
Mycorrhizae are fungi that form symbiotic relationships with plant roots, helping them absorb water and nutrients like nitrogen and phosphorus more efficiently.
90% of all plants rely on mycorrhizal fungi to thrive. Without this relationship, many plants would struggle to survive.
Fungi in Medicine:
One of the most famous medical discoveries, penicillin, was derived from a fungus. This antibiotic has saved millions of lives by fighting bacterial infections.
Fungi are used in producing various other medications, including immunosuppressants (preventing organ rejection) and cholesterol-lowering drugs.
The Largest Living Organism:
The honey mushroom in Oregon is the largest living organism on Earth, covering over 2,000 acres and is estimated to be over 2,400 years old. This underground network kills trees as it spreads, making it both a marvel and a menace in forest ecosystems.
Fungi and Human Health:
While fungi can sometimes cause problems (athlete’s foot, ringworm, etc.), they are vital to life. Only about 300 species of fungi are harmful to humans, while the rest are beneficial or neutral.

Fun Fungi Facts
The term "fungi" is the plural form of "fungus."
Some mushrooms glow in the dark due to bioluminescence! These fungi are known as foxfire.
A fungus called Ophiocordyceps can control the minds of insects, turning them into “zombie” hosts to spread spores.
