Quite many of the scientific names that we use for mushrooms actually do date from ancient times, and are known through the writings of the Greeks and Romans. It is known that edible mushrooms were collected from forests in ancient Greek and Roman times and highly valued, though more by high-ranking people than by peasants.
The Greek words for various fungi are: ἀγαρικόν, ἀμανῖται, ἀσχίον, βωλίτης, ἴτον, κεραύνιον, μίσου, μύκης, πέζις, σπόγγος etc. And the Latin name: agaricum, boletus, ceraunium, fungus, hervella, misy, pezicae, suillus etc.
