Pseudoplatyophrya nana (KAHL,1926) FOISSNER,1980.DIC.

Pseudoplatyophrya nana (KAHL,1926) FOISSNER,1980.The large yellow arrow indicates the feeding tube specialized for the puncture of fungal cells upon which P. nana feeds. This tube projects from the ventral surface of the cell.The red arrow indicates the small adoral organelle composed of about 7 ciliated kinetids just posterior to the base of the feeding tube. The green arrow indicates the curved paraoral membrane to the right of the feeding tube. From a non-flooded Petri dish culture of topsoil collected at a public park in Boise, Idaho.November 2006.DIC.

Pseudoplatyophrya nana (KAHL,1926) FOISSNER,1980.DIC.

Pseudoplatyophrya nana (KAHL,1926) FOISSNER,1980.The yellow arrow indicates the feeding tube by which P. nana punctures and feeds on fungi and yeast cells. The green arrow indicates the unusually large oblong micronucleus.DIC.

Pseudoplatyophrya nana (KAHL,1926) FOISSNER,1980.DIC.

Pseudoplatyophrya nana (KAHL,1926) FOISSNER,1980.The red arrow indicates the large refractile bean-shaped micronucleus. The micronucleus conforms to the surface of the macronucleus but lies outside the nuclear envelope. One of the two cilia of the posterior terminal dikineted of of kinety 2 is elongated to almost the length of the cell (yellow arrowhead). The shorter cilium of the pair is shown by the green arrowhed). DIC.
