초록

The genus Daldinia is a member of the Xylariaceae that has brown to dark brown and phaseoliform single cell ascospores with a conspicuous full germ slit. The isolate of D. childiae collected from Mt. Deuk-yu in Korea were compared with similar taxa, D. eschscholzii and D. concentrica.. Ascospores were $11{\sim}13{\mu}m{\times}5.5{\sim}6{\mu}m$ in size, light brown to brown, unicellular, ellipsoid-inequilateral, with dull round ends. Ascospore showed very faint ornamentation at ${\times}7.0k$ magnification. It is one of the main morphological characteristic Korean collection of D. childiae under SEM level and a main reason of reinterpretation of D. concentrica in Korea. Using KOH-extractable pigment color of stroma, D. concentrica that also has supported the SEM level investigation. Daldinia concentrica, having those characteristic recorded in Korea, should be renamed as D. childiae. However, the isolate will be the first record as D. childiae, having precise morphological description in Korea.
