Abstract: Morphological characteristics of several Myxobacteria were studied comparatively to get more knowledge of Myxobacteria and lay a foundation for their classification and identification. Stereomicroscope（SMC）、scanning electron microscope（SEM）and transmission electricity microscope（TEM）were used to observe the fruiting body, colony, vegetative cell and myxospore of Myxococcus xanthu 42-lyheh-1, Myxococcus fulvus sp-lmz-1, Myxococcus stipitatus 42-4-1, Pyxidicoccus fallax 42-10-3, Corallococcus exiguous 42-3-1, Corallococcus coralloides42-x1-4, Corallococcus macropsporus sp-lmz-2, Archangium gephyra 42-10-1 and Cystobacter minus 42-mts-2. This further description of the morphological characteristics will be the foundation of classification of Myxobacteria.
