GO:0000144	Definition	Composed of the conserved family of filament forming proteins called septins as well as septin-associated proteins, a septin ring initially forms in unbudded cells at the future site of bud emergence in close apposition to the cytoplasm face of plasma membrane. The ring expands into an hourglass shaped collar as the mother-bud neck develops during bud formation. The septin ring acts as a scaffold for other proteins that function at the bud neck and as a diffusion barrier to prevent the flow of some membrane proteins from the bud into the mother.
