A New Image Based Taxonomic Guide for cyanoScope users is now on the iNaturalist.org webpage. The guide provides detailed images of cyanobacteria genera with accompanying key physiological characteristics and notes on their ecology, toxicity, similar looking genera, and other useful information. The guide can be used in conjunction with posting your microscope images to help aid in identifications. This guide is being developed by Dr. Robin Matthews of Western Washington University with the help of Dr. Bryan Milstead and Dr. Betty Kreakie. Thanks to the efforts of Dr.’s Matthews, Milstead, and Kreakie, the guide will continue to be updated.
