How big are fungi?
Yeasts are microscopicyou could fit several hundred of them, side by side, along the diameter of a pinheadas are individual hyphae. In some fungi, hyphae may mass together to form fleshy structures such as mushrooms. There are even fungi with filamentous bodies that extend for miles! Some of these form mushroom-like structures that pop up on tree trunks far apart from one another, but you cant see most of the filamentous body that extends through the soil between the trees. Photos taken from airplanes show the shape of the giant fungus by revealing the damage it has done to plants.
