I found this in a river in central Indiana. Looks like a mushroom to me but I'm interested in what you guys think.

Hey, everyone. I found this a few years back and thought how strange it would be for a mushroom to achieve fossilization, so I kept it as a sort of trophy on my desk until losing track of it during a move to a different city and then forgetting all about it. I found it again earlier today, however, and was once again struck by how unlikely a mushroom fossil was, especially one not embedded in amber or stone. After some investigation, the odds seem even greater that it can't be. Nevertheless, the gills seem undeniable to me, and it's as light as you'd imagine a fossilized mushroom would be. I figured I'd bring the mystery to people who would enjoy solving it, so here we are. Thoughts? Did the cosmic mycelia arrange a discovery too synchronous to allow the possibility of a cold and empty universe devoid of meaning? Or am I just some jerk with a rock? In case it matters, this was found in central Texas some time in late 2016. Unfortunately, I can't recall the exact moment of discovery right now. It was either in the hill country near New Braunfels or along a hike and bike trail in North Austin.

I found this in a load of river rock on a job site along with several geodes. The load came from a local river quarry. I think it's a mushroom but I really have no idea.

Is this a petrified or fossilized mushroom? I found it on our lakeshore in Ottertail county Minnesota . I have looked on the web and have found out that mushrooms are rare . Would love some ID help . I would also like to know what the difference is between fossilized and petrified.

I found about 10 miles outside needles, CA in a dry river wash were I was looking (and sucsefull) in finding tons of petrified wood (will attach those pics as well). Please let me know what you think it is and if it is worth authentication at Arizona university or something like this.

Hello! What is this? Thank you!

I found this on the shore of a lake. At first I thought it was a petrified mushroom. It looks very similar to a mushroom. But, someone mentioned it could possibly be a horn coral. I really have no fossil knowledge so I'm just interested in what this possibly could be. It's very cool looking.
