Unidentified_plant_or_fungi

This is in my backyard under a pecan tree. It's always in shade and since I moved here last year, there is a build up of decaying leaves and is a snail and bug haven. I've searched several times on multiple sights looking for fungi and have had no luck learning what it might be. It hasn't really changed since I've been here a year and a half. Oh, and it also feels like rubber, not brittle.
