Hello everyone, can anyone one tell me what type of mushroom is growing in my yard based on the information/pictures below? I near Nashville, TN. The mushrooms were found in my yard in partially shaded areas under two trees. They grow in clusters and are very short (barely at the level of the top of the grass). They turn brownish as they age and are silimar in color to the back side of falling leaves when they're new. I tried to get a spore print by pressing the gills on white paper but the transfer was mostly clear with a few grayish smudges. I don't think I have a very distinct sense of smell when it comes to mushrooms but they smelled similar to a portebella in my opinion. I would like to know if these mushrooms are harmful to pets. I have no intentions on eating them.

Hello everyone, I'm hoping someone can help me identify this mushroom. It was found in my backyard in Tennessee just below the top of the grass. I picked one in the same location a few weeks ago. I would like to know if it's harmful to my two dogs and if so, how I can go about getting rid of it for good. The area in the yard isn't covered by shade and doesn't tend to hold moisture other than morning dew. Thanks in advance!
