| Generally speaking, fungus refers to all fungi, bacteria and slime molds. Thus phycomycetes, neurospora, basidomycetes, and deurteromycetes belong to this group. By mushrooms, we mean most of the basidiomycetes with caps and stems such as the pine-mushroom and oak-mushroom, and some of the ascomycetes, which includes the peziza and hellvela. Phycomycetes and deurteromycetes are not considered mushrooms |

| Furthermore, mushrooms can be classified by their method of nutrient intake. |
|
Fungi
generated by
decomposition |
Grown in compost resulting from fermentation of straw and grass .Represented by button-mushrooms. |
| Rotten wood fungi |
Oak-mushrooms, auricularia, Celtis sinensis, Pleurotus ostreatus, Grifola fromdosa, and several other mushrooms use the operation of enzymes putrefy wood and intake necessary nutrients. These mushrooms were originally found in naturally in rotten wood and similiar wood is now being used to cultivate them. They use their own enzymes to decompose undigested polysaccharide, such as cellulose and lignin, and convert them into substances that can be used in their metabolism. |
| Mycorrhiza |
Includes the pine mushroom, Boletus edulis, and Amanita melleiceps, which symbiotically live on the tiny roots of plants. These mushrooms' symbiotic relationship to the plants is called mutualism on living things because special organs are linked to the living roots to absorb nutritive substances. |
| Parasitic fungi |
These mushrooms absorb nutrients from living animals and plants, and the relationship is not symbiotic. Ar millaria mellea are parasitic on trees and Cordyceps militaris are parasitic on insects, spiders, and other mushrooms. |

| Domestic oak-mushrooms are classified according to the shape of the pileus, or "cap," and can be divided into "Hwago, Hyanggo, Hyangshin, and Donggo." |
|
| The pileus of the Hwago is barely opend, and the flesh is thick. The surface of the pileus is cracked like a turtle shell and contains a lot of white powder between the cracks. The pileus of the well-known Donggo opens less than 50%, and the edge of the pileus is sufficiently rolled. The flesh is thick and slight cracks can be seen on the surface of the pileus, but with few wrinkles. |
|
| The pileus of the Hyangshin is opened, more than 80% and the flesh is thin. Hyanggo's opening-degree is between that of Donggo and Hyangsins, where the shape is either hemi-globous or oval. |
|
| Oak-mushrooms are widely produced across the country, but 60% of the total are produced in Chungchong and Gyeongbuk Provinces. Especially, the Chungbuk Province produced, 1557 tons in 1998, covering 38% of the entire oak-mushroom production. |
|
| Oak-mushrooms are also produced in Jin-an (Jeonbuk), Yangsan and Keoje (Gyeongnam), Changheung and Hwasun (Jeonnam), and Wonsung (Kangwon). |
