Hyphae the feeding network
The vegetative (nutritionally active, as opposed
to the reproductive) body of most fungi is
usually hidden, being diffusely organized around
and within the tissues of the food sources. Most
fungi are multicellular, composed of tiny
filaments called hyphae. The hyphae are composed
of cell walls made of chitin (the same material
that makes up the external skeleton of an
insect), a cell membrane, and cytoplasm. The
hyphae form a interwoven mat called a mycelium,
which is the "feeding" network of a fungus.
