  • Re: Malaga Cove rarity

    Thanks for your help both. Dick, I'm embarrassed to say I just flicked past T. tripolaris having quickly discounted it as not having flat enough poles. Still

    Charles & Beats, Aha, I thought so!  Charles proves that he does indeed know the genus Auliscus better than I -- that ID is spot on, the Schmidt illustration

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.
