Kenneth G. Rainis and Bruce J. Russell. 1996. 287 pages. This is probably one of the easiest to use and most informative guides to microorganisms available. Organized into 4 categories (monerans, microfungi, protists, and microanimals), each organism is described by habitat, characteristics, behavior, and taxonomic grouping, and is accompanied by a full-color photograph. The 115 microorganisms described here should represent 75 to 90% of your finds. Tips on collecting and viewing, along with suggested projects, are included. Flexicover.
