The genus of Hypoxylon, well known wood degrading fungi, is a member of the Xylariales, which has woody to carbonaceous, brown to dark brown stromata. Hypoxylon moriforme, which was isolated from heavily decayed hardwood, is fairly described by electron microscope. The isolation of H. moriforme will be the first record and the first description in Korea. The species collected, having small size of ascospores $7.5\sim9.0\times2.5\sim4.0{\mu}m$ and asci $75\sim130\times3\sim5{\mu}m$, are taxonomically compared with H. truncatum, which is well known as a popular species in Northeast Asia. And H. bovei and H. annulatum, which are the tropic to subtropic species and also compared with other temperate species of H. moriforme.
