Nature of Sparassis crispa

[Stametsfam]

     I am perplexed by Sparassis crispa. Not mycorrhizal,
 it does seem to be dependent on complex ecological
 constituents. I have gotten so far as to get a flat
 plateau of convoluted ridges - an aborted  fruitbody -
on  sterilized conifer sawdust. Does anyone have any 
insights into its ecology or suggestions for its cultivation
 - indoors or outdoors in natural landscapes. Does anyone
 know of any successes in cultivation?

     Thank you very much.
