Cryptodifflugia spec. 16 µm, aperture 4.5 µm

 

 

This small ovoid, almost spherical, Cryptodifflugia species was present in a sample brought from Cuba by a tourist (2018). The sample was a piece of moss on a tree about 1 km from the cabin where Fidel Castro had his command post in 1958. The moss was rinsed with demineralized water. The water was kept in a glass with sediment on the bottom. I made some wet mounts of the sediment. This species multiplied easily both in the sediment and the wet mounts. The nucleus was remarkable because of a second smaller kind of nucleolus or something else, between the larger central nucleolus and the nucleolar membrane. The specimens also carried a lot of debris around the aperture.
Measurements: Shell Length 16.0-18.1 µm, Breadth 14.5-15.6 µm, L/B 1.1-1.2; aperture 3.8-4.5 µm; nucleus 6.0-6.4 µm, central nucleolus 3.2-3.4 µm, eccentric 'nucleolus' 09.-1.6 µm (n=4).
