During the course of a survey of sapstaining fungi in Korea, a Leptographium was isolated from Pinus densiflora and P. koraiensis logs, infested with the bark beetle Tomicus piniperda. The fungus grew optimally at 25 C on 2% malt extract agar and showed a high level of tolerance to cycloheximide. The Leptographium has unusually short conidiophores and is morphologically similar to L. pini-densiflorae, L. lundbergii, L. yunnanense, and the Leptographiumn anamorph of Ophiostoma crassivaginatum. Comparisons of DNA sequence data for three gene regions, as well as morphological characteristics, confirmed that this fungus represents an undescribed taxon. We consequently provide the name Leptographium koreanum sp. nov. for it here.
在对韩国变色真菌进行调查的过程中，从受松墨天牛侵害的赤松和红松原木中分离出一种长喙壳属真菌。该真菌在25℃的2%麦芽提取物琼脂培养基上生长最佳，对放线菌酮具有高度耐受性。这种长喙壳属真菌的分生孢子梗异常短，形态上与日本长喙壳、伦德伯格长喙壳、云南长喙壳以及厚壁长喙壳的长喙壳型无性型相似。通过对三个基因区域的DNA序列数据以及形态特征的比较，证实该真菌代表一个未描述的分类单元。因此，我们在此为其命名为韩国长喙壳新种。
