Abstract
"What are truffles"," opens with a dramatic painting of lightning, tree roots, mycorrhizae and truffles to introduce truffles in history, including ancient speculations (myths) about their origin. A new one to me is that they come from the testicles of Adonis, buried and multiplied by The Furies. Indeed, one Spanish term for a truffle is "turma de tierra," literally a testicle of the earth (we'll return to "turma" later). The relationship of hypogeous to epigeous fungi is briefly noted.
