  Mycelium - Wikipedia, the free encyclopedia
Mycelial mats have been suggested (see Paul Stamets) as having potential as biological filters, removing chemicals and microorganisms from soil and water.
The use of fungal mycelia to accomplish this has been termed "mycofiltration", although there is no reason to suspect that the process is any different from that of bioremediation using fungi.
Mycelium can also be used to cultivate psilocin and psilocybin mushrooms.

 Method for obtaining mold spore material - Patent 4280000
This leaves some of the mycelia within the medium, and some medium and spores may be removed with the barrier and lie on the opposite side of the barrier from the first group of mold spores and mycelia.
By peeling the sheet 17 from the medium 13, the spores 21 and the mycelia 23 on the face 25 are separated from the spores and mycelia on the face 27 and/or in the medium 13.
Following drying, the removed mold spores 21 and mycelia 23 are sieved by a sieve 31 to separate at least major portions of the mold spores from the mycelia to thereby obtain the sieved mold spore material 32.

Shiitake mycelia extract is considered valuable by modern herbalists to support treatment for chronic fatigue syndrome, herpes simplex types 1 and 2, western equine encephalitis, for liver problems such as hepatitis, and for other virus-induced conditions.
The polysaccharide-protein complex, a new peptidomannan, KS 2, and a water-solubilized lignin derivative, EPS-3, are key constituents of the extract.

 Patent 6,558,943
Before propagating fungal mycelia in the SSF medium, the mycelia may be pre-cultivated in a solid culture medium and then in a liquid medium.
After the mycelia have multiplied to cover most of the medium, approximately 0.5 cm in diameter of the mycelia are cut and transferred toga flask containing a liquid culture medium.
After the mycelia have been inoculated, aerated, and thoroughly mixed with the SSF granules, the SSF granules-containing bottle is sat on the shelf in the incubator until harvest time.

Cells were harvested by filtration, washed successively with cold sterile water and cold acetone (10 ml acetone per gram wet weight of mycelia; 1:10, w/v) on a Buchner funnel.
The shrunken mycelial mat was held for 3h under cold acetone (1:10, w/v) at —20 C. The mat was transferred to fresh cold acetone (1:10, w/v) and stored for a further 3h at —20 C. The dehydrated mycelia so obtained were desiccated under vacuum (to remove acetone vapors) for 20 min.

The ascomycota fruiting body is composed mainly of entangled monokaryotic hyphae from the male and female mycelia rather than of dikaryotic hyphae formed from the joining of hyphae from the two mycelia, as in the basidiomycota.
Most varieties of yeast do not form multicellular filiments like the mycelia and hyphae of other fungi, though they do live in massive groupings called colonies.

Cell wall type, sugars in extracts, morphology and color of mycelia and sporangia, G + C content, membrane phospholipid composition, and heat resistance of the spores are all important in classifying these organisms, as is comparison of 16S rRNA sequences and pulse-field electrophoresis of large DNA fragments produced by restriction endonuclease digestion
