Marine. Unicellular; small, centric cells. Marine medium.Characterized by shells (tests) made of silica, in two parts.

Freshwater. Filamentous; H-shaped cell walls. Soil-water medium.

Characterized by green plastids and cell walls composed of cellulose.

Freshwater. Unicellular; lunate. Proteose agar.

Characterized by green plastids and cell walls composed of cellulose.

This filamentous cyanobacteria is comprised of heterocysts and akinetes that are terminally located on the filament.

Freshwater. Filamentous. True branching, dimorphic structure. Basic culture solution.

Shipped in a form that provides the best quality specimen. Most are supplied in 16 x 125 mm tubes, 2 oz. jars, or 8 oz. jars..

Marine. Filamentous; unbranched thallus. Erdschreiber’s medium.

Characterized by reddish plastids (rhodoplasts).

Freshwater. Unicellular; heart-shaped cell. Soil-water medium.

Characterized by a lack of rigid cellulosic walls, instead these organisms have pellicles made of protein. They store paramylon instead of starch.

Marine. Unicellular. Erdschreiber’s medium.

Characterized by reddish plastids (rhodoplasts).

Marine. Unicellular; contains same pigments as other Golden Algae but contains haptonema, unique to Haptophyceae. Coccoid, from coccoliths. Marine medium. Characterized by golden yellow plastids.

Axenic culture. Food organism. Tetrahymena medium.

Characterized by cilia; nearly all possess two types of nuclei.
