Light initiated fruit body primordia of Coprinus congregatus Bull, ex Fr. grown at relatively high temperature (25°C) require a single dark period or low‐temperature induction for completion of fruit‐body development. The dark period requirement varied with the temperature regime during the inductive dark period A minimum requirement of 2.5 h was found al 15–20°C. Darkness always promotes development of fruit‐body primordial, but cannot, be regarded as an absolute necessity until temperature exceeds about 17.5°C. Normal development of me primordia without darkness was obtained by lowering the temperature to 10°C for 6 h. It appeared that at high temperatures two successive stimuli were required for basidiocarp maturation, a light‐off and a subsequent signal light‐on signal. On the contrary, at 10°C a single low‐temperature signal seemed to be involved. Thus, induction of fruit‐body development could be produced by alternative pathways. These developmental features have been extended to other fungi and compared with the flowering processes of some short‐day plants.
