I believe this is Hysterangium separabile. Found in PA the outer surface bruises pinkish. About marble sizes some about 50 percent bigger and some smaller.

I agree with Hysterangium, at least.

Currently the genus Hysterangium is larger than I am, and that’s saying something. I believe the key at the Forest Science Lab at Oregon State University currently has something like 12-15 different species. And this could be something new. The species epithet separabile refers to the easily separating peridium from the usually greenish to blue-black peridium. The cartilaginous columella is present in the photo. A close-up of the freshly-cut peridium would also be helpful: sometimes it bruises or changes color upon exposure to air. When very mature, H. separabile that I’ve found becomes very soft and brittle, and often has an aroma of overripe olives.

Under Conifer trees i believe may be spruce
