<p>  (1) A new genus Pseudotaxiphyllum Iwats. was segregated from Isopterygium. The new genus is easily distinguished from Isopterygium by having gemmiform propagules, well differentiated annuli, mostly dioicous inflorescence, and by lacking pseudoparaphyllia on stems and branches. Seven species were transferred to the new genus from Isopterygium. Six species were reduced to the synonymy. (2) A new combination, Isopterygiopsis pulchella was made. The species has papillose rhizoids from leaf axils, differentiated annuli, and filamentous propagules, but no pseudoparaphyllia on branches and stems. These characters are similar to Isopterygiopsis muelleriana.</p>
