Abstract

Morphological and culture characteristics of the novel Phellinus linteus variant KACC93057P collected in Korea were characterized in this study. The surface of the was angular, sessile, tough-woody, concentrically zonate, and dark brown in color. Basidiocarppores were circular, with 5-7 pores per mm. The hyphal system was dimitic, and basidiospores were ellipsoid or oval, $4.5-6{\times}4-5$, exhibiting characteristics typical of P. linteus. The optimum temperature for mycelial growth was $25-30^{\circ}C$, and optimal pH for growth was 5-7. The mycelial growth rate of P. linteus KACC93057P was faster than that of other P. baumii isolates. On growth medium, KACC93057P formed aerial mycelia with density higher than that of other isolates. The internal transcribed spacer (ITS)-ribosomal DNA sequences were closely related to the sequences P. linteus complex.
