Abstract
The ability of the decay fungus Chondrostereum purpureum to grow within birch (Betula pendula and Betula pubescens), aspen (Populus tremula), rowan (Sorbus aucuparia) and willow (Salix caprea) stumps or root systems is unknown, although such information would be crucial in understanding its impact on the vegetative growth of broadleaved trees, their ecology and potential biocontrol.
Saplings of these tree species were cut and inoculated with the fungus. After 3 months, 47, 14, 0 and 0% of birch, aspen, rowan and willow stumps, respectively, were dead, and C. purpureum was frequently present within the stumps of all species. In more than half of the birch stumps investigated, the fungus had penetrated into the roots unlike in the other tree species.
Our results indicate that C. purpureum can utilize the woody material of birch better than that of other species, and that penetration into the roots is needed to kill the host
