Cell type: (AH) ascogenous hypha/ascus
Component: Ascogenous hypha/ascus, immature
| Characteristic | State | Code | Images |
|---|---|---|---|
| Immature septal pore | simple with single central pore | 1 |  |
| Immature septal pore associated structures | endoplasmic reticulum associated with toroid occlusion | 1 | |
| Immature septal pore occlusion | toroid occlusion, i.e., donut-like with central pore | 2 | |

| Notes | ZIO stains lumen of pore membranes, endoplasmic reticulum, and nuclear envelope; PA-CA stains plasma membrane and toroid plug; polysaccharides localized in septum, plasma membrane, and pore membranes. |
| Character Quality | Good |
| Fixation | formaldehyde and gluteraldehyde or glutaraldehyde with osmium postfix; cytochemical staining with osmium tetroxide-zinc iodide (ZIO), or phosphotungstic acid-chromic acid (PA-CA); polysaccharide staining with periodic acid, thiocarbohydrazide or thiosemicarbazide, and silver proteinate |
