First Report on Isolation of Penicillium adametzioides and Purpureocillium lilacinum from Decayed Fruit of Cheongsoo Grapes in Korea

Two species, Penicillium adametzioides and Purpureocillium lilacinum, were isolated from decayed grapes (cv. Cheongsoo) in Korea. Each species was initially identified by phylogenetic analysis of a combined dataset of two genes. Internal transcribed spacer (ITS) and beta-tubulin (BT2) genes were used for identification of Penicillium adametzioides, and ITS and partial translation elongation factor 1-alpha (TEF) genes were used for identification of Purpureocillium lilacinum. Morphologically, they were found to be identical to previous descriptions. The two species presented here have not been previously reported in Korea.

Two Species of Penicillium Associated with Blue Mold of Yam in Korea

During 2007 survey of post-harvest diseases of yam performed in May and June, severe tuber loss caused by blue mold was observed in Iksan, Cheonbuk Province. Two species of Penicillium were isolated from the infected tubers. Based on beta-tubulin gene sequence analysis, and cultural and morphological characteristics, the isolates were identified as Penicillium sclerotigenum and P. polonicum. P. sclerotigenum, which is a novel to Korea, is presently described and illustrated.
