Abstract

A survey to assess the diversity of wound-associated Ophiostomatales and Microascales, the so-called ophiostomatoid fungi, on Korean native trees, was undertaken in 2017. Wounds were artificially created, and a fungus resembling a species of Sporendocladia was consistently isolated from the exposed cambium and inner bark of artificially induced wounds on Quercus variabilis. Morphological examination and DNA sequence comparisons based on the internal transcribed spacer (ITS) and 5.8S regions of the rDNA confirmed the identity of the fungus as Sporendocladia bactrospora. This is the first report on S. bactrospora occurring on Q. variabilis in Korea.
