I have one mushroom that's seemingly healthy and growing and another that is closed up and decidedly *not* healthy. They were purchased and placed at the same time, about 5 weeks ago, and have had identical treatment. The sick mushroom was initially larger and seemed healthier than the smaller green one, but started going down hill about about two weeks ago. Any ideas why one mushroom seems to like things and the other goes "tango uniform"? What can I do to rescue this sick mushroom?
