Three Gram-negative, facultatively anaerobic bacterial isolates were obtained from the fruiting bodies of the edible mushroom Hericium erinaceus showing symptoms of soft rot disease in Beijing, China. Sequences of partial 16S rRNA gene placed these isolates in the genus Pantoea. Multilocus sequence analysis based on the partial sequences of atpD, gyrB, infB and rpoB revealed P. eucalypti and P. anthophila as their closest phylogenetic relatives and indicated that these isolates constituted a possible novel species. DNA-DNA hybridization studies confirmed the classification of these isolates as a novel species and phenotypic tests allowed for differentiation from the closest phylogenetic neighbours. The name Pantoea hericii sp. nov. [Type strain LMG 28847(T) = CGMCC 1.15224(T) = JZB 2120024(T)] is proposed.

Four Gram-negative-staining, facultatively anaerobic bacterial isolates were obtained from the fruiting bodies of the edible mushroom Pleurotus eryngii showing symptoms of bacterial blight disease in Beijing, China. Nearly complete 16S rRNA gene sequencing placed these isolates in the genus Pantoea. Multilocus sequence analysis based on the partial sequences of atpD, gyrB, infB and rpoB revealed Pantoea agglomerans as their closest phylogenetic relatives. DNA-DNA hybridization and phenotypic tests confirmed the classification of the new isolates as a novel species. The name Pantoea pleuroti sp. nov. [type strain KCTC 42084(T) = CGMCC 1.12894(T) = JZB 2120015(T)] is proposed.

Four Gram-negative-staining, facultatively anaerobic bacterial isolates were obtained from a fruiting body of the edible mushroom Pleurotus eryngii showing symptoms of soft rot disease in Beijing, China. Partial 16S rRNA gene sequencing, together with partial rpoB sequencing, placed these isolates in the genus Pantoea. Multilocus sequence analysis based on the partial sequences of gyrB, rpoB, infB and atpD revealed Pantoea dispersa and Pantoea gaviniae as their closest phylogenetic relatives and indicated that these isolates constituted a possible novel species. DNA-DNA hybridization studies confirmed the classification of the new isolates as a novel species and phenotypic tests allowed for differentiation from the closest phylogenetic neighbours. The name Pantoea beijingensis sp. nov. [type strain LMG 27579(T) = KCTC 32406(T) = JZB2120001(T) (deposited at Institute of Plant and Environment Protection, Beijing Academy of Agriculture and Forestry Sciences)] is proposed.
