Abstract:Fifteen injured Picea abies stems infected with Amylostereum and 14 stems with A. chailletii were cut and dissected. There were no significant differences between the spread of A. areolatum and that of A. chailletii within the stems. During the first 10 years after injury, average vertical spread for both species was 2.8 m, and spread over stem cross section constituted approximately 130-160 cm2, thus affecting 30-40 per cent of the total cross section area. Tunnels made by woodwasp larvae were encountered in every analysed stem, and in all cases they were situated within the columns of decayed wood. Correlation analyses showed positive relationships between wound size and length of decay, between tree diameter at breast height (d.b.h.) and spread of decay over stem cross section, between tree d.b.h. and length of decay, and between width of annual growth rings and decay cross section area.
