Identifying specimens can be a challenging process, especially when relying solely on light microscopy and limited by a small collection of literature resources. A specimen may take months, or sometimes years, to identify, but with still no guarantee that the identification is correct. Many species today require culturing, electron micrographs, and/or genetic analysis to be identified with certainty. Consequently, I have many specimens from past seasons that remain unidentified. I thought I would post some of the more intriguing ones so others can hopefully share their expertise and aid in the identification. I thank everyone for their contributions over the years. Maintaining this website has been an ongoing learning (and enjoyable) experience.
