OK one thing about your comment bothers me...unless your a practiced and trained mycological professional you should NOT be looking for wild shrooms to consume. NEVER eat wild shrooms unless it is something like a Morel or Shaggy Mane or something that is a proven identification.
First reason is because WE dont know where you live,.... nobody can tell you what to look for because wild magic mushies vary in strain vastly across the USA.
I could tell you to look for this or that and assume it grows in your area and youll take my advice and find something to consume and DIE.
If you have had acid and whatever else the cool kids are eating/smoking these days.... I would suggest you take your time and find a shroom you can trust. Even if this means you find some on the illegal street market. I would advise someone to buy from someone before picking wild shrooms. And even buying shrooms can be risky unless you really know who your dealing with...
If you really want to try shrooms that bad .....then grow your own from spores off a reliable website. Shroomery.org and Mycotopia.com among others share a WEALTH of info on cultivating shrooms this way...
This will provide you with plenty of knowledge and understanding of comsuming/growing a safe and real magic substance that wont kill you...
But to answer the original question, mushrooms are safe in moderation, they can burn you out if your dumb and eat them too much but in my experiance people like to take breathers between shroom trips,,,
Just mark my words now, DONT look for them in the wild if it is your first thought of trying them.....because the odds are against you that it will be your first and last time doing that.
Get spores from littleshopofspores.com they r fast and a good old Iowan business with good honesty...also fast anywhere in USA.
DONT DO PF TEK.....go straight to a Grain TEK and spawn to Horse poo...
Grow your own and enjoy...dont risk finding your own and dying...
