Mating tests were used to identify 282 basidiocarp specimens of Armillaria collected in 15 Chinese provinces, mostly in northern and southwestern parts of the country. Fourteen intersterile taxa were found, including the species A. borealis, A. gallica, A. mellea s.str., A. ostoyae, A. sinapina and A. tabescens and eight so far unnamed taxa called Chinese Biological Species (CBS) C, F, G, H, J, L, N and O. The CBS F might be A. singula, previously recorded from Japan, but six Chinese groups, C, H, J, L, N and O, are probably new biological species. The sexual system of 13 taxa is tetrapolar heterothallism. Homothallic forms also were found; they show a low degree of sexual compatibility with A. mellea s.str. and tentatively are included in the CBS G, but it is unclear whether this is a homogeneous group. Notes are presented on the distribution and ecology of the identified taxa.
