Özet

Occurrence of Heterobasidion annosum s.l. was investigated in 15 coniferous stands in the Giresun and Pontic Mountains in north-eastern Turkey. basidiocarps of the fungus were found in 11 stands. Fifty-two basidiocarp specimens of Heterobasidion were collected from stumps of Abies nordmanniana ssp. nordmanniana and two from stumps of Picea orientalis. Pure cultures were isolated from the basidiocarps and identified with the aid of mating tests. Forty-five (90%) of the specimens collected from A. nordmanniana were identified as H. abietinum and five (10%) as H. annosum s.s. The former species was also found twice on P. orientalis. This is the first report of H. annosum s.s. for Turkey and the first report of H. abietinum on P. orientalis. Heterobasidion abietinum seems to be mostly a saprotroph on A. nordmanniana.
