Questions

I have small brown mushrooms growing in groups on my lawn. Is there any way of removing them for good. They seem only to grow after it rains for a few days. It is realy annoying as i try to take good care of my garden, thanks for any remedies you can give me.

I planted my rhurbarb in a sunny/shady site in my garden,a few weeks now the leaves are being eaten away and the plant is wilting. What could cause this and is there any cures???
