An '''''ostiole''''' is a small hole or opening through which [[algae]]<ref>Fletcher, R.L. 1987. ''Seaweeds of the British Isles. Volume 3 Fucophyceae (Phaeophyceae) Part 1'' p.304 British Museum (Natural History) {{ISBN|0-565-00992-3}}</ref> or [[fungi]] release their mature [[spore]]s. 

The word is a  diminutive of [[wikt:ostium|"ostium"]], "opening".

The term is also used in [[higher plant]]s, for example to denote the opening of the involuted  [[syconium]] ([[fig]] inflorescence) through which [[fig wasp]]s enter to [[Pollination|pollinate]] and breed.
The species pharamacosycea have an arrangement  interlocking pattern but there is an exception because of insipdia because it is partly cover the ostiole. On the adaxial side of the bracts is made out of cubic cells, that has a staining reactions and contain phenolic compounds. 

Sometimes a [[stoma]]tal aperture is called an "ostiole".<ref>"Synergistic Pectin Degradation and Guard Cell Pressurization Underlie Stomatal Pore Formation", {{doi|10.1104/pp.19.00135}}</ref>
