Definitions:

Fungal Filaments

The thread-like structures, or hyphae, that make up the mycelium of a fungus.

Mycelia

The vegetative part of a fungus, consisting of a mass of branching, thread-like hyphae, often found underground.

Hyphae

The long, branching filamentous structures of a fungus, which form the mycelium that is considered the vegetative part of the fungus.

Zygospore-Forming

Refers to a mode of sexual reproduction in some fungi where a zygospore, a thick-walled spore, is formed by the fusion of two haploid cells.
