Bill, there are some good ones that grow in cow pies, you can tell the more "recreational" ones by pinching the stems, if they turn bluish purple and they have a ring "halo" on the stem leftover from the cap, whitish beige cap and black gills, you could be in for a wild ride. I found some psilocybe caps larger than my hand, easily bigger around than a personal pan pizza. Don't care for the results of ingesting them, though, too unpredictable with what can happen. Those were also perfectly legal to possess for "personal use" where I lived as a teenager - something about a supreme court ruling stating you couldn't outlaw a fungus? Dunno.
Rafed, no deadhead here. I spent a lot of time between the woods, citrus fields and cowfields when I was younger, when i wasn't out clubbing till the wee hours of the morning. I met some amazing people and had some wild times, wrassled some mean gators too.
