ABSTRACT
Various types of ectomycorrihzal root were observed from the bases of the basidiocarps collected from the four different soils of WalAk Mt., JoRyeong Mt, MinJuJi Mt. and hills near Korea National University of Education; The dichotomous ectomycorrihzal roots were mainly found to be from the interactions of the Pinus roots with the basidiocarps of Boletus and Amanita species. The black single bat-like ectomycorrihzal roots with the darken rhizomorphic mycelia were mainly found to be from the interactions of the Quercus roots with the basidiocarps of Russula species. The pyramid and the monopodial-pinnate ectomycorrihzal roots were also found to be from the interactions of the Pinus and deciduous tree roots with the basidiocarps of Russula and Boletus species. The distinguished structures of the mantle and Hartig net in the cortex layers were observed to be from the roots related to the genus of Pinus in the anatomical sections. However, the aggregated (premeated) structures of mantle and Hartig net in the cortex layer were found to be in the black and bat-like ectomycorrihzal roots. The structures of cross section in the ectomycorrihzal roots, especially the roots related to the host-plants of Pinus, were observed to be different from those according to the fungal species of the basidiocarps collected. The ectomycorrihzal root not reported or confirmed by the anatomical sections were newly found to be from the bases of the basidocarps of Amanita castanopsidis, Boletus laetissimus, B. violaceofuscus, B. speciosus, Clitopilus prunulus, Leccinum rugosiceps, Russula. alboareolata, R. bella, Strobilomyces confusus, Tylropilus neofelleus, and T. plumbeoviolaceus. From the observations mentioned above, the various types of ectomycomhzal roots were speculated to be formed between the different host plants and the different species of basidiocarps.
