Ascus

/ˈæskəs/ noun

Definition

A sac-like structure in certain fungi that contains and releases spores; the basic reproductive unit in ascomycete fungi.

Etymology

From Latin 'ascus' (leather wine bag or sack), borrowed because the spore-containing structure resembled a bag. The word was adapted from botany in the 1800s. Related to 'asci' (plural) and 'ascospore.'

Kelly Says

Scientists borrowed the word for 'wine bag' from ancient Latin to describe fungal structures because they looked like little sacks—it's a great example of how scientists reuse old words when new structures resemble familiar objects!
