Rick, we call those Shaggy Mane up here, interesting how names vary from place to place, smiling. have that great and most wonderful day, with health. Cindi
Cindi, that is exactly what I thought at first, but was not sure, and after a lot of reading and investigation found that these are NOT shaggymanes. No inkyness, rounder. Since I wasn't sure I made really really sure of what they are

They are definately shaggy parasols

http://en.wikipedia.org/wiki/Shaggy_parasolI checked, double checked, triple checked, and possibly a fourth and fifth check, especially since there is a poisonous sortof lookalike. And then started out first by only eating a little bit just in case.
Better than shaggymanes imho.....I did see some shaggymanes in the lawn at work and thought about getting them, but with all the chemicals that go on lawns I decided to take a pass.
