As might be expected, chytrids are adapted to live in an aquatic environment. In the Chytridiomycetes there are six orders, each with distinct zoospore architecture: Chytridiales, Spizellomycetales, Rhizophlyctidales, Rhizophydiales, Cladochytriales, and Lobulomycetales (Hibbett et al.

Most are saprotrophic with some members being pathogenic on plants, animals, protists and other fungi. Phylum Chytridiomycota. Chytrids reproduce both sexually and asexually, which leads to the production of zoospores. The kingdom Fungi contains five major phyla, which were established according to their mode of sexual reproduction or use of molecular data. The following is a brief description of each phylum. They are one of the few groups of fungi with active motility, producing spores that move using a single flagellum. Scientific Names.

The parasitic chytrid Batrachochytrium dendrobatidis is thought to be responsible for a worldwide decline in amphibian populations. When most species reach a B. dendrobatidis threshold of 10,000 zoospores, they are not able to breathe, hydrate, osmoregulate, or thermoregulate correctly. Some chytrids are saprobes while others are parasites that may be harmful to amphibians and other animals. Reference taxon from EOL Dynamic Hierarchy Trunk, Globicultrix M. Krings, N. Dotzler & T. N.

Select reasons why chytrids differ significantly from other fungi ☆most members are aquatic ☆the reproductive cells have flagellum. This name is derived from a Greek word chytridion, which means little pot, and this describes the structure that contains unreleased zoospores. Chytrids are zoosporic fungi classified in the phylum Chytridiomycota, which currently includes two classes, Chytridiomycetes and Monoblepharidomycetes. There are five phyla of fungi: Chytridiomycota, Zygomycota, Glomeromycota, Ascomycota, and Basidiomycota. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Some species thrive as parasites on plants, insects, or amphibians, while others are saprobes. The only class in the Phylum Chytridiomycota is the Chytridiomycetes. Like all fungi, chytrids have chitin in their cell walls, but one group of chytrids has both cellulose and chitin in the cell wall. It is estimated that there are approximately 1000 species of chytrids. Chytridiomycota (true chytrids) are aerobic zoosporic fungi that operate as saprotrophs and pathogens in freshwater, brackish, and marine habitats, and are also abundant in soil.
