摘要：One new species of lichenicolous fungus ( Endococcus xanthoparmeliae ) along with four new records ( Cercidospora caudata , Clypeococcum cladonema , Epicladonia simplex and Lichenostigma cosmopolites ) are described based on floristic work on lichens and lichenicolous fungi in the Bogil, Chuja and Jeju Islands of South Korea, bringing the total number of lichenicolous fungi species recognized in South Korea to nineteen. The new species grows on the epilithic foliose lichen Xanthoparmelia coreana , while Cercidospora caudata , Clypeococcum cladonema , Epicladonia simplex and Lichenostigma cosmopolites grow on Caloplaca bogilana , Xanthoparmelia coreana , Cladonia sp. and Xanthoparmelia coreana , respectively.The new species is described in detail and compared with the morphologically most similar species of the genus, while brief description and ecology is being provided for the new records. Furthermore, presence of Endococcus verrucosus in South Korea is also being confirmed and a brief description of that too is also provided
