| 1. | The head is granular because of the ostioles of the embedded perithecia.
|
| 2. | The asci elongate into the ostiole, and discharge the ascospores outward.
|
| 3. | The wall is thin and fragile and is yellow to brown, with a short ostiole.
|
| 4. | The infructescence is scion, which is a tiny hole in the crown ( the ostiole ).
|
| 5. | Mature puffballs release their powdery spores through the ostiole when they are compressed by touch or falling raindrops.
|
| 6. | The spores are released through a small opening at the apex, the "'ostiole " '.
|
| 7. | It draws water in through its ostioles and filters out food particles such as bacteria and other micro-organisms.
|
| 8. | The columellae are not connected to the ostioles, but rather, terminate within the gleba at some distance from them.
|
| 9. | Inside the pycnidia are branched and unbranched conidiophores with two-celled pycniospores, which later are ejected from the pycnidial ostiole.
|
| 10. | Female fig wasps arrive carrying pollen from their natal tree and squeeze their way through the ostiole into the interior of the syconium.
