Pronunciation varies by accent · noun
(mycology) A small hole or opening through which certain fungi release their mature spores..
The Erysiphacae may possibly have given rise to the Laboulbeniales, the only other group in which a single daughter cell of the oogonium is responsible for the asci, and perhaps to the lower Pyrenomycetes also; these, like the Erysiphaceae, have regularly arranged asci, and in Chaetomium fimete the perithecium is without an ostiole.
Use ostiole when its meaning, tone and grammar fit the full sentence. A synonym is not always a direct replacement.
