    Charles, Oops, I was not clear in my last post.  I did not ID 60 taxa in one afternoon -- I merely listed them, altogether different.  It just consists of

    I posted a higher magnification image of D. nitescens. The outer double rows of areolae show up better. I am trying to understand the rows of fingers on either

    Dick, I liked /Diploneis nitescens/, too. Once I expanded the Stidolph plate, I could see what you meant about the double row of areolae between the ribs along

Group Description

This group is a forum intended for those with a serious interest in the study of diatoms (Bacillariophyta). These microscopic organisms are famous for their ubiquitous occurrence in aquatic environments, and for the beauty of their silica-walled frustules (shells). They are among the most important primary food producers, and constitute the base of many important aquatic food chains.

Many of our members are interested in the taxonomy and evolution of the diatoms, while others have an interest in diatoms as esthetic objects. Others may have deeper interests in the ecology of diatoms. We see all of these interests as being fully compatible.

The purpose of the group is to facilitate: (a) communication among diatomists at all levels of expertise; (b) the sharing of images and data regarding diatoms; (c) the furtherance of education concerning diatoms; (d) discussion of diatom collecting techniques, and the cleaning and mounting of diatoms for observation with the light microscope; (e) assistance in identifying diatom specimens; and (f) other purposes that may arise as the group evolves. The group is moderated, the moderators being Dick Carter (United States), Leszek Wolnik (Ireland), and Raymond Hummelink (The Netherlands).

The image on our group homepage was made by Prof. Bill Dailey, and shows the diatom Kittonia elaborata (Grove & Sturt) Grove and Sturt. It is from the famous Late Eocene deposits of Oamaru, New Zealand.
