Psilocybe semilanceata

The notorious Magic Mushroom

Well I suppose at some stage I would had to do a feature on this mushroom. A select few people I meet often presume that as a mushroom hunter, I only go looking for this particular species. Well that’s just not so – I was in the right place at the right time as I stumbled across these bad boys. Simply observed for identification reasons – honestly officer!

Psilocybe semilanceataThe Magic Mushroom or Liberty Cap (Psilocybe semilanceata) is the most notorious of all the hallucinogenic mushrooms (of which there are many), this being one of the most common and potent!

It contains a chemical cocktail of psychoactive ingredients, most notably ‘psilocybin’ (hence Psilocybe) which is a naturally produced psychedelic compound, and is the main active substance. Ingestion of several mushrooms, whether eaten fresh, dried or powdered and added to food etc, can produce a variety of ‘psychedelic’ experiences similar to those produced by LSD. Since 2005 it has been made illegal to be in possession of this mushroom (in whatever form) and is labelled as a Class A drug – so there you go.

The mycelium (the vegetative part of the fungus) feeds on the decaying matter of grass roots, so they are very at home scattered in pastures, lawns (sometimes parks), grassy roadsides and paths.

The first thing to note is that the cap of the mushroom is hygrophanous, meaning it will change colour depending on how much moisture it retains. In wet conditions the colour will be yellowish-brown / brown with a slight olive tinge. It has a glutinous viscid layer which can be delicately removed. As it drys out the colour fades to pale buff or whitish with a dark spore stained edge.

But the small conical cap remains a similar shape throughout these changes. It is elongate with striate markings (more noticeable when moist) with a distinctive small bump at the very top (umbo).

The thin white/creamy coloured stem (sometimes with darker yellowish hues) is relatively long compared to the cap size, and can grow up to 7 or 8cm high. Sometimes you may notice a blueish tinge at the very base. The gills are pale creamy-grey at first, but as the mushroom matures they become a dark purple-brown.

I’m not at liberty to say where I found these (or where to find others for that matter) as I was on a private reserve where I had permission to study. So please no questions about that on the blog or via email, thanks.

There are plenty around at the moment, but be aware that they’re just for looking at …right folks?

Before I sign off, I’ve selected a few good links on the amazingly enormous subject of Magic Mushrooms, covering their history in culture and beneficial medicinal research:

      You always get them between September to November. I can smell them sometimes I did last week I the smell takes me back to when I first took them. The only acid that comes near their intensity is the microdots that were about in the 90’s. You get outstanding colours and mad visuals. I once saw rainbows shooting off a full moon.

    Where can you find these in England/Cumbria? I hunt for mushrooms and want to know what they look like and where to find them, just in case I pick one by accident. Please send some pics and info. Thanks.

      They’re widespread all over the UK in pasture land and grassy areas. November being a good time especially after rain. It’s best to do an image search of the mushroom to see more pictures, as I don’t have many examples. All the information on it’s looks are in the post or visit wikipedia for more detail.

          To the best of my knowledge, I don’t think there are any dangerously poisonous look-a-likes. I had read in a mycology magazine that there were American species (accidentally brought across) that looked similar and were poisonous, but for the life of me I can’t find the info again! I doubt very much they are in abundance or widespread. Just be careful in identifying all elements of the Liberty Cap to be 100% sure.

      Lots of amateurs have their theories as to what conditions are important: altitude, SW facing, length of grass, animal pasture etc. etc. It is fundamentally just about luck.

      • J C Harris
        J C Harris says:

        Yes, there are many theories. One report was that someone always found them on one side of this grassy hill (west side). I’m thinking that the fungus was simply staying moist (out of direct sunlight) for as long as possible. That implies some clever thinking from the mycelium! Weird? or just coincidence?

      Hi Raymond (and all who may want to know)
      I do not have any information regarding the locations or whereabouts of where Liberty Cap’s will be. I’ve had an overload of requests, and although I appreciate you’re interest, I must have to stop replying and ask others not to request via a comment. I can not assist in this matter.
      Thanks for understanding.

      Almost every cow field and there’s plenty of them in Cumbria as I’m from Kendal and that’s where I picked in my youth lots of great memories recent research suggests that the magic mushroom can help with depression and anxiety they should be more studies into this because I believe my mental health is excellent having had mushrooms

      Get out and have a walk!
      Some fresh air and a nice wander around several fields and parks will do you good, whether or not you find what you’re looking for.

      I always waited for the first frost and then went out picking – had areas of glorious abundance near me in Hertfordshire back in the 80s and 90s but those sites no longer produce, would love to find some more as just a few on a Friday night was such fun. I agree with the depression study – our brains can confine us in the mundane, mushrooms taken well can help us to be more free and laugh….a lot.
