The mycelium of the Garden Giant, S. rugoso-annulata forms only fruiting 
bodies after considerable time. The substrate is colonised in three to 
four weeks, but it takes eight weeks before primordia are formed. One 
article by Poppe and Sedeyn in Mushroom Science  XII 1989 suggests 
that sterol, auxine or flavenol could stimulate primordia formation.

Another suggestion is that the depletion of nutrients leads to primordia
