Beginning of July to beginning of September. I finally found out what this is! I searched hackberry tree (which it was growing on) and this mushroom came up immediately (current synonym Perenniporia robiniophila). I’m so glad I finally figured this out.
Pore surface pictures aren’t very clear at all, and are shadowed however in person they were very clearly fresh and living pore surfaces, and were dark grey in color. They also smelled very strongly, as sweet fruit-floral an odor as you can get while also having the regular “mushroom smell” somewhere too.

Found on our lawn adjacent to black edging. On the other side of the edging is hemlock mulch from Menominee County, Wisconsin.
