Condensed mycelia just prior to the onset of fruiting of Lentinus edodes accumulated adenosine 3′,5′‐cyclic monophosphate (cAMP) 9.2 times that of non‐aggregated mycelia (control). Immature fruiting bodies also contained cAMP, 7.9 times that of the control, while cAMP content was low in mature fruiting bodies. The immature fruiting bodies contained the highest level of adenylate cyclase activity, i.e., 3 times that of the condensed mycelia, suggesting that the presence of a high level of cAMP is required for the onset of the fruiting and cAMP may be rather actively metabolized in the stage of maturing fruiting bodies.
