WHAT IS A MYCELIUM?
Mycelium is the vegetative part of a fungus consisting of a mass of branching, threadlike hyphae that exists below the ground or within another substrate.
The familiar hat-like head and stalk of a mushroom carries the reproductive structures of ascomycetes and basidiomycetes fungi and is formed of hyphae, but considered separate from the mycelium part of the fungus.
It is through the mycelium that a fungus absorbs nutrients from its environment.
It does this in a two stage process.
Firstly the hyphae secrete enzymes onto the food source which breaks down polymers into monomers.
These monomers are then absorbed into the mycelium by facilitated diffusion and active transport. Mycelium is also a vital component in many ecosystems in that it helps increase the efficiency of water and nutrient absorption of many plants and also is vital to the decomposition and breaking-up of plant material to form the organic part of soil and to release carbon dioxide back into the atmosphere.
WHAT IS HYPHA ( PLURAL HYPHAE)?
In fungi, the hyphal filaments form the feeding thallus, called the mycelium.
Hyphae are also found enveloping the gonidia in lichens, making up a large part of their structure.
A typical hypha consists of a tubular wall, usually made of chitin, which surrounds, supports, and protects the cells that compose a hypha.
For most fungi, a cell within a hyphal filament is separated from other cells by internal cross-walls called septa (singular septum).
Septa may contain pores large enough for for ribosomes, mitochondria and even nuclei to flow between cells.
Some forms of parasitic fungi have a portion of their hyphae modified to form haustoria that are able to penetrate the tissues of a host organism. Similar, yet mutualistic forms of penetrating hyphae called mycorrhizae are important in assisting nutrient and water absorption by plants.
To put it in nutshell; hyphae are the branches of a mycelium;and mycelium is the body of a fungus. The other term is Thallus.
Just as branches are important for a plant / tree; hyphae are important for a fungal mycelium.

hyphae are the little white threads that grow from fungal spores. basic unit of a fungus. long before the mushroom is seen above ground there are tons of threads of hyphae under the ground.

Aliens are usually portrayed as not wearing clothing because authors of such stories realize that the compulsion to wear clothing, even when one doesn't have to, is a human perversion that people of other planets aren't expected to have. Utility - Small backpack. Fulfills all my needs to carry stuff that pockets do. Protection - Live in a warm climate and avoid arc welding, space travel, and arctic exploration. Style - People are fine, just the way we are. Comfort - Nothing is more comfortable than wearing nothing. Cover - Clothing traps germs and bugs against us. People easily get used to seeing other humans. Naturists know better, but you'll never know, because you've never tried it.

Yes, hyphae are tubes that fungi form, and they're used for feeding, and they can anchor the fungi down. They can also form reproductive structures.
