Does anyone know what the heck this is?

I know this is EXTREMELY off topic, but I noticed this pop up in my yard a few days ago. I had 2 or 3 of these pop up in a different spot in my yard about this time last year. It is the size of a fist, and as you can see they litterally rip the ground open when they come up. I know it is some kind of fungus but I nor anyone around me have ever seen anything like it before, and it seems to only be happening in my yard. Do any of you know what this is, or maybe have seen something like it?
