Document Summary

Some chytrids are parasites & do not produce assimilative hyphae like those of eumycotan fungi forms produce assimilative structures rhizoids simpler forms are unicellular more complex forms are coenocytic. Hyphae are thick, non-septate and delicate, collapsing in dry air. Sexual reproduction (teleomorphic phase) involves conjunction of morphologically similar gametangia (branches hyphae) to form zygosporangia(zygo te that undergoes meiosis) Colonize terrestrial substrates such as bread, overripe fruit and dung. Hyphae are thin but resistant to drying out, septate and anatomosizing. Thallus formed by the mass of hyphae is called mycelium. Short lived & consists of few special cell types produced inside the ascomata the teleomorph reprod structures. Very long lived is free-living and produces basidiomata, the teleomorph reproductive structures. Includes 3 artificial groups that include both ascomycete and basidiomycete fungi;
