Fungi, their diversity, structures, and biological processes. Culinary uses belong in Ingredients; their ecosystem relationships belong in Ecology.
Test your knowledge with these top questions!
How does a feeding mycelium break down food before absorbing nutrients?
Fungal enzymes work outside the body, turning large food molecules into smaller ones that the network can absorb.
What gives a gilled mushroom spore print its spoke-like pattern?
Spores drop from the gills onto the surface below, leaving a record of the cap underside without using ink.
What falls from a mushroom cap to form a spore print?
Individual spores are usually too small to see clearly, but a mass of them forms a visible deposit.
Why do mushroom collectors often make spore prints on both black and white paper?
A print can help narrow down a mushroom identification, but matching spore color alone cannot establish that a mushroom is edible.
Which feature of a mushroom spore print helps identify the mushroom?
A mushroom cap and its spore deposit can have very different colors, so the cap alone does not reveal the print color.
Mycelium can be processed into a flexible, animal-free substitute for which clothing material?
Sheets of fungal mycelium can be made into materials for bags, shoes and furniture without using animal hides.
Mycelium can bind farm waste into a biodegradable alternative to which protective packing material?
The fungal threads grow around loose plant pieces, holding them together in a lightweight shape that can be composted.
Why can a mushroom reappear after its cap and stalk have been picked?
Picking a mushroom removes a fruiting body, while the longer-lived feeding network can survive inside soil or wood.
Piedmont's famous white truffle season peaks each autumn in which Italian town?
Alba's prize is Tuber magnatum, a white truffle so hard to grow on farms that it is still gathered from the wild.
The truffles shaved over pasta are the fruiting bodies of which kind of organism?
A truffle cannot make its own food, so it trades soil minerals and water for sugars from a partner tree's roots.
