A Species of Agaricus or Marcolepiota?

[boomer2]

Well this fellow was growing in shaggy red bark much (cedar) at the Bank of America in the U-District. I picked it and then took it into a shop and photographed in the counter. See the shaggy scaled cap. It had dark brown gills and had a spider web from the stem to the inside of the cap. I removed the web with the eraser end of a pencil since I do not like spideys crawling on my skin.

I was told it was a Lepiota, primarily a species of Macrolepiota, but Lepiotas were placed into a genus based on white spores and Agaricus have dark brown spores, so mopt likely this is a species of Agaricus

Waitling on Alan Rockerfeller to properly ID it.
