What is this fungus in my Garden? (0/1)

I have had pine mulch under my children's playground for 2 years. This year a strange fungus is coming up everywhere in the mulch. It looks attractive and yellow for a day then like a strange outer space alien plant after that. If I touch it, it releases many black spores at this point. Please have a look at the attached pictures and tell me if you know how to safely get rid of it and if I should be concerned about it for any reason.
Thanks.

DO NOT send attachments to a non-binary NG.

Your attached pictures did not show up on many news servers, so many of us won't see them. Of those who even have a chance of seeing them, many of them filter-out binaries on their end. Others will simply not open any message with an attachment. And others who set their newsreaders to download messages so they can view them off-line will be annoyed that one of them is a huge binary in a discussion group.
Also, most news servers set aside a certain amount of space for each group. As newer messages come in, older messages are pushed out. Posting a text message usually means one text message is pushed out the back end. Posting a picture may mean that two, three or more days worth of discussion will be pushed off the back end. If there was only enough room set aside on the server for a week's worth of discussion, your picture may have pushed off a significant portion of the discussions, and folks who only check in once a week will have to go to an archive site like Google to find out what they missed.
Instead you should have posted to a binary group like alt.binaries.pictures.gardens, and/or provided us with a link to where we could find the picture(s).

Can only guess as my newserver doesn't allow binaries in discussion groups. (See Warren's post for a pretty thorough explanation of the issue regarding binaries.)
However, when anyone posts a 'what is this strange stuff in my mulch' question, I first think of slime molds:

This is a standard problem and questions about it appear every year. You can google for it.
