IPA: /bəˈsɪdiəˌspɔr/
KK: /bæˈsɪdiəˌspɔr/
A type of spore that is produced by certain fungi, specifically on a structure called a basidium, and is involved in the reproduction of these fungi.
The basidiospore is essential for the life cycle of many mushrooms.
Basidiospore is formed from "basidium" (from Greek "basis", meaning base or pedestal) and "spora" (from Greek "spora", meaning seed or to sow). The word refers to a spore that is produced on a basidium, which serves as a base for the reproductive structure in certain fungi.
Think of a 'base' ('basidium') that produces 'seeds' ('spora') — that's what a basidiospore is, a spore produced from a base structure in fungi.
