The distinguishing standard is the presence of a septum that separates the hyphae cells horizontally.
Fungi with a septus are classified into mycomycetes, and those without a septum into lower fungi.
The lower fungi have multiple nuclei within a cell, which is called a coenocyte. Because they have multiple nuclei within a cell, their growth and propagation speed is faster than mycomycetes.
The species generally called mushrooms belong to mycomycetes and have a macroscopic structure that is distinguishable to the naked eye.
Mushrooms differ from green plants in that they have no chlorophyll and propagate by microscopic reproductive units called spores instead of seeds.
All mushrooms are heterotrophic, obtaining nutrients from the outside through their hyphae.
While most of them extract organic materials by decomposing dead matter, some types are parasitic or symbiotic.
Myxomycetes are classified into Ascomycetes that form an ascus with ascospores endogenously, and Basidiomycetes that form a basidium with basidiospores exogenously. In Korea most of the Ascomycetes are Pyrenomycetes and Discomycetes. Among the Pyrenomycetes, Cordyceps militaris, Daldinia concentrica, and Xylaria polymorpha are the most common. Among the Discomycetes, Peziza vesiculosa, Scutellinia scutellata, Helvella lacunosa, Morchella esculenta, Bulgaria inquinans, and Chlorosplenium aeruginosum are the most common.
Basidiomycetes consist of Hymenomycetes and Gasteromycetes. Typical mushrooms are listed in the Hymenomycetes.
