Acrospore
Definition
A type of asexual spore, conidium, or microscopic reproductive body that develops and separates exclusively at the upper extremity or apical zone of a specialized hyphal filament (conidiophore). This cellular structure, specific to lower fungi, is formed through terminal constriction or budding, ensuring highly efficient airborne dispersal of genetic material in the environment for species propagation.
