配对试验与菌株的蜜环菌在文化中被用来确定蜜环菌的种类和它们在日本各地的分布。从日本广泛分布的20个担子果中分离出10个蜜环菌间不育群。然后将来自每个互作不育组的2 - 4个单倍体测试菌株与生物和形态学物种配对，其中单倍体测试菌株来自先前研究中鉴定的欧洲和北美。然后将日本单倍体测试菌株与190个单倍体或二倍体菌株配对，并使用相容性反应将其鉴定为种。在日本鉴定的10个不育群中，有7个被鉴定为A。gallica、细叶甲A. nabsnona、黑腹拟步行虫A. ostoyae，A. cepistipes，尖吻拟步行虫A. mellea、黑果草A. sinapina或A. tabescens。其中三组与任何试验种属均不相容。本文还讨论了日本生物种的分布和寄主关系。
Pairing tests with isolates of Armillaria in culture were used to identify species of Armillaria and their distribution throughout Japan. The existence of 10 intersterile groups of Armillaria was determined by pairing haploid single spore isolates obtained from 20 basidiocarps from a wide geographic distribution in Japan. Two to four haploid tester isolates from each intersterile group were then paired to biological and morphological species with haploid tester isolates from Europe and North America identified in previous studies. Japanese haploid tester isolates were then paired with 190 haploid or diploid isolates and compatibility reactions were used to identify these to species. Of the 10 intersterile groups identified in Japan, 7 were authenticated as A. gallica, A. nabsnona, A. ostoyae, A. cepistipes, A. mellea, A. sinapina, or A. tabescens. Three of the groups were not compatible with any of the tester species. The distribution and host relationships of the Japanese biological species are also discussed.
