These mushrooms were found growing in the grass in my backyard and are dark in colour and gilled. They have a smooth cap that is campanulate with no bulb on the tip. The cap is not a perfect circular, it’s irregular in shape with minority flaring edges. There are no grooves, so I will say it’s striate. I could not see any veil features in these mushrooms. The gills are free, close, and emarginate. The breadth of this mushrooms’ gills is narrow, and they’re close together. The edges are even/entire. The stem location is central, and it is smooth and equal. No bulbs could be seen. I can’t seem to actually tentatively identify these mushrooms because their dark colour doesn’t match any of the ones we have gone over. However, I’ll go on a whim and say that it could be H. substrangulata.
