ABSTRACT
A fungal-speci–c phase-contrast opaque body, the Spitzenkörper (apical body), located at or just below the tip of the apical cell, is thought to drive hyphal growth. The
Spitzenkörper consists of a heterogeneous population of vesicles surrounding a core that contains polysomes, microtubules, and actin, and serves as a supply center for the distribution of vesicles containing materials necessary for tip extension.
