Plural of 'acervulus'; small cup-shaped or disc-shaped structures where spores are produced in certain fungi.
From Latin 'acervulus,' the diminutive form of 'acervus' (heap). The '-ulus' ending makes it 'little heap,' and 'acervuli' is the standard Latin plural form used in scientific taxonomy.
These tiny fungal structures are like miniature fruit factories—they're so small you'd need a microscope to see them, but they contain thousands of spores ready to spread the fungus. Scientists realized fungi had organized these microscopic production lines millions of years before humans invented factories!
