Which structure is elongated buds that have failed to separate and are connected together to form a link-of-sausage appearance?

• A. Septate hyphae
• B. Aseptate hyphae
• C. Pseudohyphae
• D. True hyphae

Answer: (C)

Pseudohyphae form when budding yeast cells fail to detach after division, creating a chain of elongated cells that remain connected and resemble a string of sausages. This appearance comes from successive buds that do not separate completely, so you see linked, sausage-like cells rather than a single, continuous filament. It’s a hallmark of certain yeasts, like Candida, under specific growth conditions. This differs from true hyphae, which are long, continuous filamentous structures that make up the mold form and can be septate (with cross-walls) or aseptate (without cross-walls). Pseudohyphae are not true hyphae because the cytoplasm isn’t continuous through a seamless filament—the cells stay attached only at constricted points after budding.
