Non-septate hyphae, also known as aseptate or coenocytic hyphae, form one long cell with many nuclei. They are the more primitive form of hyphae; species with septate hyphae diverged from a common ancestor with coenocytic hyphae. Most fungi with coenocytic hyphae belong to the class Zygomycetes. While they do not form septa between nuclei, they do form a septum at branch points that connect one filament to another, preventing the entire network from being compromised if one hypha is injured.
