530 FORM TYPE SLIDE by Klaus Kemp

This type slide of 530 forms of diatoms is shown with dark ground illumination. It was produced for the author by special request by the late Klaus Kemp near the end of the 20th century. I asked him to produce a slide of every diatom he had access to. Every specimen is finely preserved with its features clearly visible with the appropriate resolution and magnification. Unfortunately, he was unwilling to supply me with a matching species list. Shown below are some of the individual forms shown at higher resolution and magnification via DIC illumination.
