Dan,
I'm kind of doubtful about the importance of having the right fungi too. I deflask Thelymitra and Pterostylis into a mix of perlite and pine based potting mix and they don't seem to get set back much. Actually, I don't know whether the easy species aren't as reliant on fungi or whether they'll associate with a wider range of common fungi than we give them credit for. I think it may be a bit of both.
