dolipore septum

The term "dolipore septum" refers to a specific type of septal structure found in fungi, particularly within the Basidiomycota group. A septum is a cross wall that divides a hypha, which is a tubular filament forming the body of a fungus. While some fungi have simple septa, the dolipore septum is more complex. It features a pore cap that surrounds a central swelling and the septal pore itself. This unique structure allows for the passage of cytoplasm and smaller organelles between cells, but it restricts the movement of nuclei. This is distinct from a pseudoseptum, which is a perforated septum found in some algae and fungi.12
