Batrachospermum is a freshwater form of wide distri- buti<i)n, with a preference for spring brooks, though occur- ring I in any water that is not stagnant. It grows in branching filaments often several inches long, enveloped in a thick coat of soft transparent mucus. The color is bluish or yellowish-green, dirty yellow or brownish. Attached to some stick or stone in a rivulet its sprays, of more than frond-like delicacy, float freely in the water. Hydrurus grows in branched colonies embedded in a tough mucilage, attached to rocks in cold mountain streams. The colonies are often several inches long. Their color is olive green. They have a pltimose appearance, and are of very graceful Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Needham, James G.
