Abstract

A Leptographium sp. unknown in Japan was isolated from Japanese red pine (Pinus densiflora) in this study. Pairing of different strains of the fungus gave rise to mature perithecia of an Ophiostoma sp. Characteristics of this teleomorph were similar to those of Ophiostoma piceaperdum, but the fungus had larger ascospores. The anamorph state had 2 to 3 primary branches, and was similar to Leptographium truncatum, L. yunnanense, L. pini-densiflorae, and particularly to L. koreanum. Comparisons of partial actin, β-tubulin, and rDNA sequences data showed that the Japanese fungus is L. koreanum. Pairing of strains from Japan with the ex-type culture of I. koreanum gave rise to mature perithecia confirming this identification. The teleomorph of I. koreanum is thus described here as Ophiostoma koreanum.
