Abstract

The occurrences of ectomycorrhizal fungi were investigated in a pine-mushroom forest at Hongcheon, Korea. The fairy rings of Tricholoma matsutake were figured by the sporocarp places of T. matsutake for three years $(1995{\sim}1997)$, and the occurrences of other ectomycorrhizal fungi were surveyed with x and y dimensions for two years $(1996{\sim}1997)$. The diameters of fairy rings of T. matsutake ranged from 2m to 10m, which indicated that the age of the fairy rings as $10{\sim}50$ years when we consider that the growth of the fairy ring used to show about 10 cm per year. Russula bella, R. sororia, R. delica and Cantharellus minor were the major species occurred on the site during the survey period, and each species occupied 16.0%, 12.8%, 12.4% and 7.0% of total mushroom occurrence, respectively. From the results, we could conclude that the surveyed stand was a productivity-declining forest from the view point of pine-mushroom production. In addition, Amanita pantherina, Suillus bovinus, Ramaria flaccida and Laccaria amethystea were considered to be the indicator species for declining of pine-mushroom productivity since some fruiting bodies of the species appeared around the fairy ring of T. matsutake.

대한민국 홍천의 송이 발생림에서 외생균근성 버섯의 발생상에 대하여 조사하였다. 송이 균환은 3년간$(1995{\sim}1997)$의 송이 자실체 발생위치를 토대로 파악하였고, 다른 외생균근성 버섯의 출현 위치는 x축과 y축의 좌표를 표시하며 2년간$(1996{\sim}1997)$ 조사하였다. 송이 균환의 직경은 $2{\sim}10m$의 범위를 나타내어, 송이 균은 대체로 연간 10 cm 정도 생장하는 것을 감안할 때 균환의 연령은 $5{\sim}50$년에 달하는 것으로 여겨졌다. 무당버섯(Russula bella), 회갈색무당버섯(R. sororia), 푸른주름무당버섯(R. delica), 애기꾀꼬리버섯(Cantharellus minor)이 조사기간에 주로 출현한 버섯이었는데 그 출현빈도는 전체 조사된 종류의 각각 16.0%, 12.8% 12.4% 및 7.0%를 차지하고 있었다. 조사자료를 분석한 결과, 연구대상지는 송이의 생산량이 감소하는 숲으로 여겨졌다. 또한, 마귀광대버섯(Amanita pantherina), 황소비단그물버섯(Suilllus bovinus), 다박싸리버섯(Ramaria flaccida) 및 졸각버섯(Laccaria amethystea)은 송이의 균환주변에 많이 출현하여 송이 생산성이 감소하는 상태에 있음을 나타내는 지표종으로 여겨겼다.
