Recently we found new Pleurotus sp. isolate KKM 1 that grew on wood logs. The experiments were conducted to study its morphological and phenotypic characters of mycelium and basidiocarps of Pleurotus isolate KKM 1 compared with other cultivated mushroom varieties such as P. eous var. APK1, and P. djamor var. MDU1 and P. florida. Pleurotus isolate KKM 1 was confirmed as Pleurotus djamor by ITS sequencing of rDNA region. Thus, the new Pleurotus sp. isolate KKM1 was named as P. djamor isolate KKM1. | Molecular characterization and phenotypic study of new pleurotus djamor isolate KKM 1
