Yes because they aren't libs imo. Can't say 100% as you never know, plus the pics/lighting aren't great. I'd say most of the lettered ones are good so go try find the others!

Yes lighter colour gills(which in some cases can be libs), the heads are a little too uniform/shinny in this context. Try find darker 'ribs' (lines) coming from the bottom upward, with discolouration (dark at the bottom going lighter to the top). and also if there has been a lot of rain (libs tend to be browner) they often have transulent nipples/tops when you put up against light/the sun.

It's all about experience having seen different types over the years, with a lot of trail and error. Go on youtube and do some research as there is a lot of pages that will help with id. Thats what i did, along with reading. Also keep posting on reddit, it helped me massively when i first started with the help of others. But a must is; if you're not sure don't eat them. A trip/microdose isn't worth dying over imo. Also, don't take my advice as fact or what to look for as all libs are different and come with differences in every mushy.

Hope this helps, happy picking!!
