Summary Introduction
Concept introduction: Chytrids are the fungal group that has a vessel-like structure called sporangium in which flagellated spores are produced. According to the recent evolutionary studies, chytrids are one of the oldest fungal lineages. Members of this fungal group are decomposers and survive in a variety of habitats.
