Notes: 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. This was growing under I believe spruce.

You may be right. I’m not expert enough to tell. A suggestion? Include a twig from the tree if you find this again: most foresters should be able to tell the tree species from a twig or even cone if included in the photo. H. seperabile and H. coriaceum both form matt-communities, and often grow on very steep slopes, where the touch mycorrhizae helps hold the rock and soil in place, while getting rid of water rapidly.

A question: were the sporocarps all partially visible above ground? Did you try looking under the existing fruiting bodies for other, less mature material?
