Boletus is a symbiotic ectomycorrhizal flesh fungi forming mycorrhizas with trees of Pinaceae, Fagaceae and Betulaceae. The species in the genus have relatively strong host specificity to enhance the growth of host plants and some of them are flavorful. But Korean rarely consumes these kinds of mushrooms and B. edulis has not been reported in this country. In the genus twenty six species have been reported in Korea, but the number is expected to increase as collection efforts are intensified. Keys to the families of Boletaceae and Strobilomycetaceae, to the genus of Boletaceae and to the species of Boletus were provided based on published keys and the descriptions of species reported in Korea. However, the key to the Boletus species did not include all the species occurring in Korea and not all the ones in the key are indigenous.

Tricholoma matsutake ectomycorrhizas are unique in their morphology: not bifurcated broom shaped roots with not easily wettable brilliant and profuse white hyphae. To understand these characteristics the ectomycorrhizas were investigated with electron microscopy. T. matsutake ectomycorrhiza have thin mantle and typical Hartig net development in the epidermis and cortex, but no fungal mantle on the root apex. There were no penetrating hyphae inside of the cells of either epidermis, cortex or stele. Inside of the walls of epidermis and cortex cells are lined with ca. $2{\mu}m$ hemispherical amyloplasts. The brilliant hyphal surface was covered with various fine amorphous granules. The hyphal cell wall was thin membrane less than $0.3{\mu}m$ thick. There is no clamp connection on the hyphae. This thin membraneous cell wall with high elasticity can be related to survival strategy of the species without plasmolysis under frequent soil water stress environment. And the coarse hyphal surface with some water repellency can control sudden inrush of water of the hyphae with an extremely low osmotic potential. It is concluded that no mantle on the tip can induce mycorrhizas not bifurcated and that finely coarse surface of T. matsutake hyphae can make the hyphae brilliantly white but less wetted.
