A couple weeks ago I walked outside and found several dozen mushrooms in the mulch/pine needles around one of our trees. I was really worried because that tree sustained a lot of damage during our snow storms last year and I was worried that maybe this was an early clue that it had died.
Then they started popping up everywhere! Here's a big collection near my compost bin:

I think maybe they sprouted from fungi that were in the mulch I bought last year from the city.
Then, while I was wondering what - if anything - to do about them, they dried up and shriveled away during our heat wave last weekend. How fun! I wonder if they will come back?
