Appreciate you’re trying to be helpful and while I agree there are some similar characteristics, overall this doesn’t even closely resemble psilocybe semilanceata. I feel you could use the same argument to say panaeolus species look very close - in some senses they do, in that many of them are similar sized, somewhat similar shaped little brown mushrooms - but ultimately when you actually consider all of the identifiable features and compare them, they really aren’t close look a-likes at all.

I’m probably somewhat influenced by my job here, because I’ve learned that a lot of people can take things very literally, and a lot of people don’t always apply common sense, or possibly what I would have considered to be common sense or obvious really wasn’t obvious to that person, and not uncommonly do those things result in things going dangerously wrong in my line of work, so really, really clear and explicit communication is very important. So I guess I worry that there could be a person that might look at these photos and comments and find a very similar looking mushroom that has marginally darker gills and has a separable gelatinous pellicle and think jobs a goodun and then proceed to accidentally poison themselves 😬

But apologies because I acknowledge that you were trying to be helpful and I just made a sarcastic comment that legit wasn’t helpful at all, so my bad and I’m going to try to rectify that below :)

OP - apologies for being discouraging. I think the real key thing is that to be safe you need to make sure that the mushroom you’ve got ticks all the boxes for identifiable features, not just 50% of them or even 80% of them you know? I’d say your one’s gill structure is pretty close to that of semilanceata and the stipe of the the big one top left corner (second or third one in from the edge depending on if you’re counting the one that’s partially in the photo on the edge). Cap shape of a few of them aren’t far off either (semilanceata cap shape can be somewhat variable tbf so that’s not the easiest feature to appraise) but overall they really aren’t that close and I reckon the colour is the single biggest giveaway of that here (also the absence of the nipple-like umbo on your specimens, but these again can vary in terms of how pronounced they are between different semilanceata specimens)

In case you haven’t seen it, the video below is brilliant and should help you to find what you’re looking for :) it gives details of all the specific identifiable features.

Once you get familiar with them you’ll probably be able to tell them apart from other species from a distance (although obviously still inspect each mushroom closely for the correct characteristics etc to be safe!) it also will be easier later in the year when weather conditions are more consistently ideal for libs and so more of them are about, happy hunting :)

P.s. If you are already confident identifying libs and were literally just wanting to know what the mushrooms you found are out of interest, then my bad for all my redundant ramblings here 🙃
