What does hyphae mean?
Hyphae are the microscopic, thread-like filaments that form the body of a fungus. They may be simple or highly branched, and they grow together in networks known as mycelia. These filaments absorb nutrients, spread through soil or other substrates, and can penetrate the tissues of plants and animals. The word is primarily used in biology, mycology, agriculture, and medical research. Although a mushroom may be the part of a fungus that people commonly notice, it represents only a temporary fruiting structure; most of the organism consists of hyphae growing invisibly through its environment. The plural ending -ae is characteristic of Latin and Greek scientific terminology, but the modern word is also easy to mistake for a group of unrelated threads rather than a specific fungal structure.

Where does hyphae come from?
The word comes from Greek hyphē, meaning “web,” “strand,” or “filament,” through New Latin and scientific English usage. In mycology, the term was adapted to refer to the individual filamentous elements of a fungal body. The adjective hyphal and related biological terms such as hyphomycete were formed within the same scientific vocabulary.
