| 21. | These fungi form meiotic spores called ascospores, which are enclosed in a special sac-like structure called an ascus.
|
| 22. | The two cells from both the protoperithecium and conidium fuse, yet their nuclei remain separate until ascus formation has occurred.
|
| 23. | The mushroom has a pale yellow or brown thimble-shaped �m, and the presence of only two spores per ascus.
|
| 24. | The spores are made in structures called operculum a lid that is opened when spores are to be released from the ascus.
|
| 25. | Perithecial, ascus and ascospore characters in the fruiting bodies are the key identification characteristics of " O . sinensis ".
|
| 26. | One further mitotic division leads to four " A " and four " a " nuclei in each ascus.
|
| 27. | The tip of the crozier fuses with the penultimate cell while walling itself off from the ascus by the formation of a septum.
|
| 28. | These nuclei migrate into a side branch growing from the base of the ascus that repeats the ascus-crozier formation innumerable times.
|
| 29. | These nuclei migrate into a side branch growing from the base of the ascus that repeats the ascus-crozier formation innumerable times.
|
| 30. | The spore-bearing cells, the operculum, a lid that is opened when spores are to be released from the ascus.
