Abstract

One of the sapstain fungal species isolated from the stained sapwood of a Japanese black pine in Korea was characterized. The fungal species is tolerant to cycloheximide and has Petosum-like synnema and Sporothrix type synanamorph which are found in the anamorphs of the Ophiostoma piceae complex group. But the species could not form perithecia on MEA. Based on cultural and morphological properties and analysis of the $\beta$-tubulin gene sequence, the fungal species was identified as Ophiostoma quercus. Here, we report mycological characteristics of the anamorphic stage of Ophiostoma quercus isolated in Korea.

한국에서 해송의 줄기변색 부위에서 분리된 변색균류중 한 종에 대하여 그 특성을 조사하였다. Cycloheximide에 저항성인 Ophiostoma piceae complex 그룹에서 보여지는 무성세대 Petosum의 분생포자경과 또 다른 무성세대 Sporothrix의 형태를 지니고 있었다. 그러나 완전세대의 모습인 자낭각을 형성하지 못하였다. 이 균류는 배양적특성, 형태적특성 그리고 $\beta$-tubulin 유전자 염기서열 분석을 통하여 Ophiostoma quercus로 동정되었다. 본 연구에서는 한국에서 분리된 O. quercus의 균학적 특성을 처음으로 보고하고자 한다.
