| 1. | Total transmittance is the ratio of transmitted light to the incident light.
|
| 2. | The spores are black-brown as spore mass and in transmitted light brownish yellow.
|
| 3. | The transmitted light passes through this boundary with no phase change.
|
| 4. | The images are made with transmitted light, creating clarity and saturation.
|
| 5. | The spores are as spore mass ochre to olive brown, in transmitted light faint-coloured.
|
| 6. | The spore mass is olive-yellow to olive, in transmitted light appearing pallidly olive-yellow, occasionally paler.
|
| 7. | The remaining transmitted light is the green component.
|
| 8. | In thin fragments it appears reddish brown in transmitted light and also leaves a red streak.
|
| 9. | In transmitted light they appear finely thorned.
|
| 10. | Directly transmitted light can, optionally, be blocked with a polariser orientated at 90 degrees to the illumination.
