Having or producing exactly two spores; characterized by a pair of reproductive cells in fungi or plants.
From bi- (two) plus porous (from Latin 'porus,' pore or opening). This combines -ous (adjective suffix) with the biological concept of spore production.
Bisporous fungi are actually quite common in nature, though you'd never know it—these microscopic organisms are quietly reproducing in soil and on food, following their two-spore strategy!
