Fungi: The Kingdom That Is Neither Plant nor Animal is a 3D virtual gallery on MyGallery3D, a walkable online exhibition of 14 works. Step inside and explore it in your browser: no app, no headset.
Step into this 3D virtual museum of fungi and walk through it in your browser: the mushroom on the wall is not the organism, only its fruit.
Fungi are not plants. Their cell walls are built from chitin, the material of arthropod exoskeletons, and they are genetically closer to animals than to plants, having split from us around one billion years ago. The body of the fungus is the mycelium, a mat of threads in the soil. One Armillaria colony in Malheur National Forest is estimated at 2,400 years old and spans some 2,200 acres.
More than 125 species of fungi glow. The light is greenish, at a wavelength of 520 to 530 nm, continuous, and produced only by living cells. Every glowing species is a white rot fungus that breaks down lignin, and all share the same enzymatic mechanism. Why they do it is unsettled: the light may lure animals that carry spores away, or warn grazers off.
Nothing grows that fast. A mushroom begins as a primordium less than two millimeters across, and the cells of the cap and stalk take days to form underground. What happens overnight is inflation: the fruit body pulls water up from the mycelium and expands cells that already exist. Raw brown mushrooms are 92% water. Parasola plicatilis can balloon, release spores and collapse within a day.
Over 90% of plants depend on mycorrhizal symbiosis. The fungus threads into the root, hands over phosphorus, nitrogen and water pulled from soil the plant cannot reach, and takes sugars in return. By some estimates mycelial networks receive well over 10% of a host plant's photosynthesis output. Fossils in the 407 million year old Rhynie chert show the arrangement already running before plants had roots.
