SUMMARY 1. Measurements of daily growth rates, colony widths and lengths and cell widths and lengths were made on Fotterella tetrachlorelloides Buck and Staurastrum longiradiatum West & West (Chlorophyceae), collected from an eutrophic reservoir close to Madrid (Spain) on nine consecutive days of June 1983.2. F. tetrachlorelloides exhibited growth followed by a period of decay, whilst S. longiradiatum grew more or less continuously throughout the observations.3. A colony length-width relationship was statistically significant throughout the growth period of F. tetrachlorelloides, but not when the population was decaying. This relationship was always statistically significant in S. longiradiatum. There was an inverse relationship between volume and daily growth rate in S. longiradiatum, but no such correlation was found in F. tetrachlorelloides.4. The time course of statistical volume distributions and daily growth rates suggested that F. tetrachlorelloides was undergoing clonal ageing during the study.
