Hypha

[1] In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium.

In most fungi, hyphae are divided into cells by internal cross-walls called "septa" (singular septum).

The Spitzenkörper is part of the endomembrane system of fungi, holding and releasing vesicles it receives from the Golgi apparatus.

The direction of hyphal growth can be controlled by environmental stimuli, such as the application of an electric field.

Hyphae are found enveloping the gonidia in lichens, making up a large part of their structure.

In nematode-trapping fungi, hyphae may be modified into trapping structures such as constricting rings and adhesive nets.

Bulk fungal tissues, cords, and membranes, such as those of mushrooms and lichens, are mainly composed of felted and often anastomosed hyphae.

[15] Hyphae are described as "gloeoplerous" ("gloeohyphae") if their high refractive index gives them an oily or granular appearance under the microscope.
