I never touch the ones that grow in my garden and they just seem to go on their own. Depends which ones you have though?

A picture would probably help. Most are totally harmless, growing on dead organic material such as decomposing wood and bark chips, or dead roots of long-forgotten trees. They are mostly beneficial, playing a major role in the decomposition of organic matter, and the fruiting bodies that we notice are usually to be enjoyed (some eaten, of course), and left to fade and spread their spores. There are a few that are killers, of plants and trees, and a small number are very poisonous if eaten. In the grass they can just be brushed away, and elsewhere, just ignored. Phil J
