Radiata pine (Pinus radiata) lumber from Australia, Chile, and New Zealand is imported into Korea where it represents one of the most important sources of timber. Blue stain of this timber is a serious problem for which an integrated control strategy is being developed. One of the fungi that has been isolated from stained radiata pine sapwood in Korea is a Leptographium sp. that has a distinct Sporothrix synanamorph. The aim of this study was to classify this fungus. Morphological comparisons showed that this fungus is distinct from all other species of Leptographium and especially L. elegans and L. francke-grosmanniae that also have Sporothrix synanamorphs. Comparisons of sequence data for the ITS2 and part of the 28S rDNA genes as well as the β-tubulin gene also confirmed that this fungus represents an undescribed taxon, described here as Leptographium bistatum sp. nov.
