Apical rings of Trichodelitschia bisporula
Joop van der Lee, 19-05-2020 09:59
Joop van der LeeWhen we are investigating characters of species under a light through microscope we do observe that in a 2D picture.
So we have to think in 3D but that is not always possible because our mindset cannot cope with the optical illusion we are looking at.
Accidentally I did find out that we can create a 3D picture by changing the focal distance from the lens to the object using a Plane Objective 100x/1.25 (photo 1 & 2). Probably by stacking photo's you will create the same effect.


The ring is elastic and the distance when the apical system is not fully developed is as follows: Diameter of the outer circular ring is 0,9 um; total diameter is 4,6 um and inner diameter is 2.8 um. Photo-3 is a ring clearly visible with a spore ready to enter.


Photo 4 the ring is connected to an ampty inner wall, photo 5 is the same situation but inside a still present outer wall.


Photo 6 shows the apical ring in the end phase with spore clicked inside and the outer wall still present. 
Photo 7 & 8 show spores inside the ring and outer wall gone.

The ring itself is more oval than it is circular. (photo 9)

Kind regards,

Joop
