i didnt read the thread you linked since it was so long. but shrooms are very easy to do. you can simply slice the polyp in a few pieces and they will eventually form a new polyp and a new mouth. if you are looking to make some $$$ you can take a polyp and cut it off its base. get some tank water and the shroom and blend it not alot, but so you still see pieces. once youve blended the shroom you simply pour the slurry over some rock, make sure that the slurry settles on the rock and is not blown around your tank. this is a sure fire way to completely cover almost everything it touches once it seeds out. some people like to cut off pizza pieces from a shroom and pin in to a rock using wedding veil and a rubber, once the piece attatches you can remove the wedding veil. the parent colony will eventually heal back to normal in a week or so...
