Armillaria spp.

Tykeria London

Taxonomy

Division: Basidiomycota

Kingdom: Fungi

Phylum: Basidiomycetes

Class: Agaricomycetes

Order: Agaricales

Family: Physalacriaceae

Genus: Armillaria

Species: Armillaria mellea

Multicellular, eukaryotic cells
This organism is a decomposer that resides in the forest
Invasive parasitic fungi, can attack a wide range of plants and trees (typically hardwoods and conifers)
Mainly resides underground
Spread by rhizomorphs can also be reproduced by spores
This species has up to 10 isolated reproductive groups
- this means it has different biological species

The researchers extracted the polysaccharides from the rhizomorphs of Armillaria mellea
These polysaccharides were then injected into mice in 100, 200, and 300 mg
As a result all mice with the injection no matter the dosage had a positive response in their immune system
In conclusion, there was an increase in the body weights, a change in the weights of the immune organ, and resisted the changes in the number of peripheral blood leukocytes
- this finding can inspire more research toward making this available for human consumption

This graph shows the results of the extracted polysaccharides being used to treat Alzheimer's
