Ergosterol (ergosta-5,7,22-trien-3β-ol) je sterol prisutan u gljivicama, i imenovan po ergotu, zajedničkom imenu za članove gljivičnog roda Claviceps iz koga su ergosteroli prvobitno izolovani. Ergosterol se ne javlja u biljnim i životinjskim ćelijama. On je komponenta ćelijske membrane kvasca i gljivica, gde ima istu ulogu kao i holesterol u životinjskim ćelijama.

Ergosterol se javlja u travama poput raži[5] i lucerke, kao i u cvetajućim biljkama, npr. hmelju.[6]. Međutim, obično se smatra da je ergosterol detektovan zbog fungalnog rasta na biljkama (kontaminacije), jer glijvice formiraju intergralni deo sistema razlaganja trave. Ergosterolni testovi se mogu koristiti za određivanje fungalnog sadržaja u travi, žitaricama i storčnoj hrani.[7][8].
