Exploring Diversity within <italic>Chytridiales</italic> and <italic>Rhizophydiales</italic> (<italic>Chytridiomycota</italic>) in Korea.

Abstract<italic>Chytridiomycota</italic> is the most species-rich phylum of basal lineage fungi with a worldwide distribution. Its species constitute essential components of freshwater ecosystems. However, the diversity of this group in Korea remains understudied. A survey of <italic>Chytridiales</italic> and <italic>Rhizophydiales</italic> fungi was conducted in soil and freshwater environments in Korea, and seven strains were isolated. Based on morphological and molecular data, a previously unidentified, novel <italic>Rhizophydium</italic> species was discovered, designated <italic>Rhizophydium multiplex</italic> sp. nov. In addition, <italic>Chytriomyces hyalinus</italic> and <italic>Globomyces pollinis-pini</italic> were isolated for the first time in Korea. Detailed descriptions and illustrations of the three species are provided. This study highlights the potential diversity of chytrid fungi in Korea. [ABSTRACT FROM AUTHOR]
