Hi Michael,
	your description sounds very much like Morchella.  I have a protocol 
for fruiting morels that you may be interested in (although it is amazingly 
complex, it is allegedly effective).  I obtained it from Fred Stevens of the 
San Francisco Mycological Society several years ago, when I took a mushroom 
cultivation course taught by him.
	I actually typed the whole thing in and tried to send it to you last 
night, but my mailer freaked out and crashed my PC just as I went to send it. 
	The gist of it is that you grow up the mycelia in a good growth 
medium, refrigerate, soak, case, then fruit.  There is a fair amount of 
humidity, CO2, and illumination manipulation involved.
	If you are interested, please send me an Email and I will be happy to 
type it up and send it to you.
