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?

    Now WHY did God put all these TERRIBLE “psychedelic” (mind-manifesting) mushrooms all over the place? Here in northern California, Psilocybe cyanescens (fairly potent) has been inadvertently spread all over the place by commercial woodchip mulch distributors. I say God should be ARRESTED AT ONCE as a big-time “drug distributor” (not really a “dealer”, since God doesn’t even charge us any $$$ for these mushrooms). Psilocybin is a SCHEDULE 1 DRUG! This MUST be stopped!

      Well, He does work in mysterious ways, and they are a benefit in their ecological role in breaking down dead organic matter and in the case of P.semilanceata, it suppresses the growth of Phytophthora cinnamomi (water mold found in soil), a virulent plant pathogen that causes the disease root rot. Two good marks there!

    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.
