Sleepy grass.

I was just reading on erowid about LSD and came across something called sleepy grass. This aparently can have fungi on it that contains LSA. I read another thing that said that horses that eat that grass stumbled and acted drunk. Since erowid didn't have a lot of information on it my question is, is it safe for humans to eat and what will the effects be? Would they be similar to morning glory seeds. Thanks for any help.
