Pinkgill sp.?

growing in a field. I'm unsure whether the grass had been fertilised or whatever. There were sheep grazing in the field. same as this spotting? http://www.projectnoah.org/spottings/23151074. I left them uncovered and the biggest one produced a pinkish spore print so does this mean they're Entoloma? They all partially dried and are now silky on cap and stem. another pointer towards Entoloma?
