Green mold of Phellinus baumii caused by Penicillium was observed in Daegu on August, 2000. The causal fungus was identified as Penicillium citrinum based on their cultural and morphological characteristics. Conidiophores one-stage branched, terminating in a whorl of 3~5 metulae. Metulae mostly 5.2~7.8㎛. Phialides were flask-shaped, 5.7~7.5×2.2~2.7㎛. Conidia were subglobose, 1.8~2.3㎛ in size.
Colonies on Czapek agar were mostly attaining a diameter of 23㎜ within 8 days at 25℃. The optimum temperature for growth of the fungus was about 20~30℃. On the basis of mycological characteristics and pathogenecity test on host mushrooms, the fungus was identified as Penicillium citrinum. This is the first report on the green mold of Phellinus baumii caused by Penicillium citrinum in Korea. The present study was carried out to investigate the preventive effect of Penicillium citrinum by backfill (sand, granite soil, and smash rock). The result showed that the use of granite was 3~10% infection rate and sand was 2~10% infection of P. citrinum.
However, the smash rocks showed no infection of this fungus. The chemical properties of smash rocks was pH 8.4, showing alkalinity. The sand and granite soil
were pH 6.1 and pH 7.5, respectively. These did not have heavy metals such as Mn, Fe, Pb and As.
