Three species of the genus Euphoriomyces (Laboulbeniales) were found newly from Korea. E. agathidii (Maire) Tavales was collected from Agathidium sp. (Leiodidae, Coleoptera). The characteristic traits of this species are the distal portion of the primary axis composed of $5{\sim}11$ superposed layers and bearing more or less the elongated appendages. E. cybocephali (Thaxter) Thaxter was collected from Pseudocolenis hilleri Reitter (Leiodidae, Coleoptera). The primary axis of this species composed of $5{\sim}9$ superposed layers is simple, not branched and a single antheridium occurs on the apex of the secondary axis. E. sugiyamae Majewski was collected from Scaphisoma rufum Achard (Scaphidiidae, Coleoptera). This species is very unique in having the antheridia formed as coner cells with lateral necks.
