The biochemistry and the physiology of the higher fungi has recently begun to attract attention among biologists. Extensive studies on fruit-body formation in Schizophyllum commune by Wessels (1965) afforded valuable information on this problem and in Agaricus, observations have been made primarily on the hormone control of fruit-body development, and the effects of different wavelength light on the precess of growth. Physiological and biochemical studies on the process of fruit-body formation and development in Hymenomycetes, especially of those fungi whose fruit-bodies are differentiated into a stipe and pileus, have seldom been reported. The present investigation was carried out using Coprinus macrorhizus as a test organism in an attempt to investigate the process of stipe elongation and test the efficacy of a shadowgraph apparatus for the quantitative measurement of short term growth in fungal tissue.
