Аннотация:Four new taxa of the lichenized, foliicolous ascomycete genus Chroodiscus are described from Southeast Asia: Chroodiscus defectus Papong & Lücking, Ch. homchantarae Papong & Lücking, Ch. khaolungensis Papong & Lücking and Ch. khaosokensis Papong & Lücking. Chroodiscus argillaceus (Müll. Arg.) Lücking & Papong ( = Chroodiscus parvisporus Kalb & Lücking) is introduced as new combination. The genus as currently circumscribed now includes 14 taxa, which are keyed out here. A short discussion on the putative evolution and taxonomic treatment of species pairs in this genus is included.
