Soft rot decay of treated wood in ground contact and loss of service-life remains an important economic issue worldwide. This study determined the identity of unclassi (204-1, 35-1, TS4M3, 25M3) isolated from wood in-service. Phylogenetic analysis clustered strains into a single clade homologous with internal transcribed spacer (ITS) rDNA showed minor differences at single bases for strains 35-1 and 25M3. Compatibility occurred between TS4M3, 25M3 and 204-1 but not 35-1, lagerbergii with strain 35-1 least aggressive. Light microscopy showed Type I diffuse soft rot cavity formation reminiscent of TS4M3, 25M3 and 204-1 but always less for 35-1. Strains 35-1 and TS4M3 showed highest Cutolerance on CuSO indicate the homology and decay morphology, although considerable intra-variation exists.fied Phialophora strainsPhialocephala dimorphospora. Sequencing ofPhialophoraor Phialophora botulispora. Birch was more rapidly degraded than pine for all strains,P. dimorphospora. Growth rates at 15, 20 and 26°C were similar for4 and micronized copper incorporated into malt extract agar plates. Results indicate the Phialophora spp. A strains represent P. dimorphospora as suggested by strong strong homology and decay morphology, although considerable intra-variation exists.
