Key judgment

Item IdentityWood ear mushrooms are edible fungi of the genus Auricularia; while the representative species of commercial black wood ear mushrooms in East Asia is managed as Auricularia heimuer, verification of the actual spawn and variety species is prioritized. ( MycoBank )
Key roleIt is an edible mushroom focused on texture, supplied for fresh, dried, sliced, powdered, HMR, school meals, and the food service industry.
production methodLog cultivation and sawdust substrate cultivation are distinguished, and recent domestic technical data describes greenhouse sawdust bag cultivation as the primary commercial method. ( Nongsaroo )
Harvesting principleManage Species/Strain·Spawn·Substrate·Culture Date·Occurrence Date·Harvest Cycle·Fruiting Body Size·Color·Thickness·Elasticity·Harvest Date as Lot required values.
Product separationSeparate Fresh → Chilled → Dried Whole/Cut → Powder and Rehydrated/Prepared Product.
Separation of similar itemsA. heimuer, hairy wood ear mushrooms, and other Auricularia spp. are separated into Species/Strain units, and other fungi such as white wood ear mushrooms and silver ear mushrooms are managed as separate entities.
domestic productionIt is confirmed that the Korea Forest Service’s Survey of Forest Products includes items for Mushrooms – Wood Ear mushrooms production volume and production value. The latest detailed raw table figures for 2024 were not directly verified in this v1.0 version and will be entered later after verification of the official raw data. ( Korea National Arboretum )
localizationThe Rural Development Administration and regional agricultural research institutes have been developing domestic varieties of black wood ear and hairy wood ear mushrooms, as well as cultivation techniques using sawdust bags and bottles. ( Rural Development Administration )
Cultivation environmentThe sawdust bag cultivation example in the Nongsaroo consultation materials suggests mycelial culture at 20–25°C and 65–75% relative humidity, and mushroom fruiting at 15–20°C and 85–90%. Management should be conducted strictly according to this protocol example. ( Nongsaroo )
Harvest examplesThe Nongsaroo black wood ear mushroom bag cultivation technique presents a harvest case approximately 75 days after inoculation and pre-harvest watering management. Since there are differences depending on the strain, substrate, and season, these are not fixed as standard values. ( Nongsaroo )
Supply and demand riskThe key factors in competition are the mixing of species and varieties, spawn quality, substrate contamination, temperature and humidity/ventilation, excessive humidity, harvesting labor, storability of fresh wood, dry moisture/rehydration quality, and imported dried wood.
Operating PrinciplesSpecies/Strain–Spawn–Substrate–Incubation–Fruiting–Harvest–Drying/Processing–Buyer Connect the RFQ.
Final goalIt connects the Species, Varieties, Substrates, Lots, and Processing History of domestically produced wood ear mushrooms all the way to Buyer repurchase.

Similarity PrincipleYou must distinguish between Auricularia species, domestic varieties, and hairy-necked snakes.

Modern phylogenetic studies indicate that *heimuer*, which is commercially important in East Asia, is a distinct species from *A. auricula-judae*, which was commonly used in the past. Therefore, the names *Heukmok-i* found in older agricultural records are not converted directly into species names; instead, the classification information of the actual spawn is verified. ( PubMed Central (PMC) )

Since the physical properties of fresh wood ear mushrooms differ significantly from those of rehydrated products after drying, the quality of dried wood ear mushrooms is evaluated separately in the Buyer Application Test for thickness, elasticity, shape recovery, and foreign matter after rehydration, in addition to the drying state .
