Hi Michael.  Morchella mycelium is fairly easy to recognize once you learn 
what it's supposed to look like. It sounds very much like the mycelium you 
ahve described. Fruiting morels is of course another matter entirely...

It is fairly easy to grow on most kinds of medium.  At least it 
grows on nearly every medium I've ever tried.  For some additional 
information on recognition of the mycelium see one of my [old] morel papers:

Volk, Thomas J & Thomas J Leonard.  1990  Cytology of the Life cycle of 
Morchella.  Mycological Research. 94: 399-406

Hope this helps. Please write if you need additonal information.
