Phylum Zygomycota_Class Trichomycetes

• Zygomycota is a phylum within the Kingdom Fungi. It includes a diverse group of fungi that are characterized by the formation of reproductive structures called zygospores during sexual reproduction. They are typically saprophytic, meaning they obtain nutrients by decomposing organic matter.
• Trichomycetes is a class of fungi that belongs to the phylum Zygomycota. These fungi are primarily known for their association with arthropods, particularly insects and crustaceans. This is because they are often found in the digestive tracts or on the external surfaces of these arthropods.
• Orders of class Trichomycetes

  • Harpellales
  • Asellariales
  • Eccrinales
• Harpellales


  are primarily associated with insects, especially aquatic insect larvae. They inhabit the hindguts of their insect hosts. The order includes genera like Harpella and Smittium.
• Asellariales


  are associated with crustaceans, particularly isopods. These fungi are often found on the exoskeleton or in the brood pouches of isopods. The order includes genera like Asellaria and Stachylina.
• Eccrinales


  are also associated with insects, particularly the order Diptera They are found in the Malpighian tubules or other internal tissues of their hosts. The order includes genera like Ascochyta and Amoebidium.
• Trichomycetes


  • They form a mutualistic or commensal relationship with their arthropod hosts. They are commonly associated with insects such as beetles, cockroaches, and mayflies, as well as crustaceans like shrimp.
• Trichomycetes


  • They are typically found in aquatic environments, especially in freshwater habitats. They inhabit the digestive tracts, reproductive organs, or other body parts of their arthropod hosts.
• Trichomycetes


  • they often form elongated, thread-like structures known as trichospores. These are part of their reproductive structures and are involved in the dispersal of the fungi and the colonization of new hosts.
• Trichomycetes play a crucial ecological role in aquatic environments, forming symbiotic relationships with various arthropods. They contribute to nutrient cycling in aquatic ecosystems, influencing food webs and exhibiting both mutualistic and parasitic relationships with their hosts. Lastly, trichomycetes stand as captivating subjects of study, offering valuable insights into the intricate relationships between fungi and arthropods.
