Twenty-four Alternaria strains have been isolated from wood samples in Korea and submitted to phylogenetic analyses. The gene trees generated from the ITS and histone gene region sequences revealed that, among the genus Alternaria, two species, Alternaria alternata sensu lato (s.l.) and Alternaria tenuissima, are involved in wood discoloration. In addition, the histone gene was useful as a marker for differentiating between A. alternata s.l. and A. tenuissima.
