|
|
Bluish green mold of Pleurotus eryngii caused by Penicillium was observed in Seungju on Feburary 4, 1999. The causal fungus was identified as Penicillium corylophilum based on its cultural and morphplogical characteristics. Conidiophores one-stage branched, terminating in a whorl of 2∼4 metulae. Metulae mostly 10∼18×2.5∼3.0 ㎛. Phialides flask-shaped, 9∼13×2.2∼2.8 ㎛. Conidia subglobose, 2.5∼3.2×2.5∼3.0 ㎛. Colonies on Czapek agar mostly attaining a diameter of 21 ㎜ within 7 days at 25℃. Colour blue-green soon becoming grey-green. Pathogenicity test by wound inoculation revealed that Penicillium corylophilum caused the same symptoms as observed in the field at 6∼7 days after inoculation.
