What is Heterobasidion annosum group S identified in north-eastern China about?

## Summary Samples of __Heterobasidion annosum__ were collected in two stands of mixed forest in Changbaishan Nature Reserve in north‐eastern China. Pure cultures were isolated from 15 specimens growing on __Abies, Picea, Pinus__ and __Populus.__ Mating tests showed that all these collections belong to the S inter‐sterility group. The compatibility of Chinese homokaryons with S homokaryons from Europe was 100%. Clamp connections appeared almost equally in both strains of each pairing, and no distinct demarcation line formed in the pairings. The mating frequency of Chinese isolates with the European F group was also high, approximately 94%. These matings, however, were usually unilateral and a more or less distinct demarcation line was present in most of the pairings. The Chinese isolates were completely intersterile with the European P group. The S group of __H. annosum__ in north‐eastern China appears to have similar morphology and ecology as in Europe. It is common on __Abies__ and __Picea__, but is not a serious pathogen in the pristine forests of north‐eastern China.
