Help With Mushroom ID

[Mac]

Hi there,

I found two different larger mushrooms (bell is 3 inches diameter on one and 4 inches on the other) both growing under conifer trees, but on different ends of a property. The gill are dark brown and crowded and I don't think they're attached. The bell of the mushroom curves upward (is it a trumpet, then?). I can't seem to find any photo that looks anything like it, but it must be common. Can you look at the two pictures I took and help me ID it?

Thanks,

Mac :-)

First, a few comments on mushroom vocabulary. The top part of the mushroom is generally called the "cap." Some caps are bell-shaped, but the bell shape may flatten as the mushroom matures. Sometime the mushroom cap may become concave, which means that it could hold water like a small bowl. There are a few mushrooms that are called "Trumpets" because the shapes of these types mushrooms are always trumpet-shaped, which includes both the stem and cap. The mushroom pictured is not one that falls into any category of trumpet mushroom.

My guess about the mushroom in the photo is that it is a species of Agaricus. But I would need more information in order to feel comfortable with even this level of ID (ID to genus). For Agaricus species, the gills are completely free of the stalk. This can be somewhat confusing because, with some types of mushroom, the attached gills may tear away from the stalk and appear to be free. The picture of the gills does appear to show "free' gills.
