This species is known to occur throughout the Republic of Korea, often in the temperate forests and on the soil beneath Pinus densiflora, Carpinus laxiflora, Quercus acutissima, Q. mongolica, and Castanea crenata. If any wild populations of this species remain at its known localities, they may be threatened by logging and wood harvesting, much like Pinus densiflora, Quercus acutissima, and Quercus mongolica, however further research is required in order to confirm this claim. Until further research regarding this species’ present distribution, habitat preferences, and potential threats is carried out, its population trends remain uncertain, and so this species is listed as DD.
The holotype of this species was initially found in the Republic of Korea, Sobaek Mts., in the vicinity of GuIn sa (temple), under Pinus densiflora and Acer palmatum, at an altitude of 596m, and at coordinates N 37°01′ 51.17″, E 128°28′ 39.41″ on the 11th August 2013. Additional specimens have been located in the following locations and on their respective dates: Republic of Korea, Bo-eun, Songnisan Mt., under Carpinus laxiflora and Quercus mongolica, alt. 350m, N 36°32′13.92″, E 127°49′45.23″, 15th August 2013; Hocheon, Dong-myeon, under Pinus densiflora and Quercus acutissima, alt. 172m, N 37°41′56.05″, E 127°57′21.52″, 18th August 2013; Mt. Gaya, Ye-san, under Pinus densiflora and Castanea crenata, alt. 225 m, N 36°43′ 17.24″, E 126°36′58.30″, 17 July 2014 Mt. Chiaksan, Won-ju, under Quercus mongolica and Pinus densiflora, alt. 289m, N 37°25′30.46″, E 128°04′09.11″, 22nd August 2015; Young dong, Sangchon-myeon, Mulan Valley, under Castanea crenata, alt. 356 m, N 36°06′02.30″, E 127°53′02.88″, 25th August 2015; Muju, Unjangsan Recreational Forest, N 35°54′04.22″, E127°24′54.14″, alt. 420m, 31st August 2016. These appear to be the only known recorded specimens of this species.
Until further research regarding this species’ potential threats and wild distribution is completed, it remains difficult to assess the current population trends of this species.
Population Trend: Uncertain
This species has been located growing on soil underneath Pinus densiflora, Carpinus laxiflora, Quercus acutissima, Q. mongolica, and Castanea crenata, within the forests of the Republic of Korea.
No literature appears to mention specifically any direct threats to this species, however it is known that some of the species with which this species has been found could be threatened. Pinus densiflora, Quercus acutissima, and Quercus mongolica are all thought to be threatened by logging and wood harvesting, however further research is required in order to assess to what extent these threats extend to the known localities of Cantharellus koreanus.
Protection of this species’ habitat may be required for successful conservation, provided that further research yields useful information regarding this species’ potential threats.
Further research into this species’ wild distribution and habitat preferences is essential for the accurate classification of this species.
