Twenty species representing five genera of arbuscular mycorrhizal fungi were isolated from twenty-four soil samples of the rhizosphere of the family Gramineae in Paekryung and Daecheong islands. A few species such as Glomus invermaius, G. marcrocapus var. marcrocarpus and Scutellospora coralloidea were recorded for the first time in Korea. The number of spores per 10g of soil was in the range of $8{\sim}337$ in Paekryung and $16{\sim}349$ in Daecheong island, respectively. The number of species per 10g of soil was $2{\sim}8$ species in Paekryung and $2{\sim}7$ species in Daecheong, respectively. Among them, G. macrocarpus var. macrocarpus was the most abundant species in both islands. The species diversity and evenness were almost similar in Paekryung and Daecheong Islands. Based on the host plants in two islands, the species diversity showed the highest value of 1.63 in Ischaemum crassipes, whereas the eveuness of species showed the lowest value of 0.35 in Eragrostis ferraginea.
