The sensitivity to gravitational stimulation of excised stems of the mushroom fruit body of Coprinus cinereus was determined using clinostat rotation to remove partially‐stimulated stems from the normal unidirectional gravitational field. For the strain and conditions tested, the presentation time (the minimum time of stimulation required to elicit a gravitropic reaction) was determined to be 9.6 min. This is the first time the presentation time has been determined for a fungal gravitropic response. Constructional details are given of the clinostats employed in the research and their further use is discussed.
