The edible ectomycorrhizal mushroom Amanita javanica is a valuable species protected by forest law in Korea. However, basic characterization data on its use as an important forest resource has been limited. This study was performed to determine mycelia growth characteristics of the domestically isolated Amanita javanica strain NIFoS 1267 on potato dextrose agar media under diverse culture conditions. Physical factors temperature, pH, and light, as well as chemical factors salts, heavy metals, and pesticides were examined for their effects on the growth of the mushroom strain. The mycelia of A. javanica strain exhibited optimal growth when cultured in dark at 30oC in media with a pH of 5–6. Normal levels of growth were observed in media containing up to 2% saline. At a heavy metal ion content of 50 ppm, mycelial growth was not affected by arsenic ion but was affected by cadmium and lead ions. In the tests performed with two pesticides used in Korean forests, the growth of the mushroom strain was not affected by the presence of abamectin, but was inhibited in media containing acetamiprid, emamectin benzoate, or thiacloprid. These results are expected to facilitate artificial cultivation of A. javanica as a new commercial product.
