| Research Abstract |
To elucidate biological species of Armillaria in Japan and its ecological features, the following facts are evident from the results.
1. Among 6 biological species of Armillaria in Japan, four of them are A.gallica, A.ostoyae, A.cepistipes, and A.mellea. And, one of them is compatible with North American biological species IX (NABS IX).
2. From the analysis of nuclear DNA content, nuclear phases of A.mellea are considered to be homothallism.
3. From the regulation of light and temperature conditions, fruit bodies of A.gallica, A.ostoyae, A.mellea, and A.tabescens are formed in the artificial media.
4. At the damaged stands of Armillaria root rot on Japanese red pines, A.ostoyae is only pathogenic fungi. Meanwhile, A.gallica and A.mellea are not pathogenic.
