Abstract:
The newest order in Chytridiomycota, Rhizophydiales, shows remarkable genetic divergence and zoospore ultrastructural diversity. From submersed mud from a marsh near an oligotrophic lake in the Patagonia region of Argentina, we isolated a previously undescribed chytrid in Rhizophydiales with unique 28S rRNA and ITS1-5.8S-ITS2 sequences and a distinctive zoospore and thallus. In a combined LSU + 5.8S phylogeny of representative taxa in the order, the nearest relative to this new species is Rhizophlyctis harderi, and their zoospores share several similar character states. A new genus is erected for this chytrid, the first to be brought into pure culture from this region. © 2008 by The Mycological Society of America.
