Name
editWhat about moving this page to Psilocybe semilanceata? As far as I know, the name Liberty Cap is predominantly used in the UK. 80.203.115.12 21:59, 27 Apr 2005 (UTC)
- no real opinions either way, but Psilocybe semilanceata is probably best. --Heah 23:31, 27 Apr 2005 (UTC)
- I agree about moving it to Psilocybe Semilanceata, as it is in fact its real name. We should rather mention that it goes by the name Liberty Cap in some groups... Opiax 11:34, 28 Apr 2005 (UTC)
- I'm not sure I understand your arguments. How is this different from any other organism with a common name and a scientific name? "Liberty cap" certainly wins the google test over "Psilocybe semilanceata". Also, for what it's worth, I believe "liberty cap" is the common name in US commerce, so it's hardly restricted to the UK. — Pekinensis 18:20, 12 May 2005 (UTC)
Thought I would expand the article as I was surprised at how little there was concerning such an important species. Modern use does focus on other mushrooms, but I feel it is neccessary to explain the recent resurgence in PS use... --DWA M217.158.132.35 15:30, 11 October 2005 (UTC)
- added pictures and edited a little --DWA M Psibaduh 12:06, 5 November 2005 (UTC)
Move
editI took action and moved the article back to "Psilocybe semilanceata". All other articles on Psilocybe species are listed under their scientific name, and this should be too, even if it does happen to have a common name that's actually in widespread use.
Hello. I was looking around the internet and according to http://www.shroomery.org/index.php/par/25319 the displayed photographs aren't Psilocybe semilanceata, but Copelandia cyanescens. Someone could clear it out? It's not only this page actually, one can just make 'image' search on yahoo.com both for P. S and C. C and he will find out that the people always mistake between these two.
Risk of mistaking this for other, potentially very poisonous mushrooms
editIn the Norwegian article there's a section on the risks of mistaking several other types of mushrooms for this one, and some of them are highly toxic. Shouldn't this be something the current article should discuss as well? __meco (talk) 18:27, 13 August 2009 (UTC)

Reversion of removal of sentence from intro
editI removed this sentence from the two-paragraph lead because I believed it lent an undue weight to a single research study that has not demonstrated any lasting significance to the subject of the article:
The mushroom has also been shown to inhibit an antibiotic-resistant form of the human pathogen Staphylococcus aureus, and it secretes antifungal compounds that help it compete for nutrients with soil microorganisms.
Many agents have been shown to inhibit MRSA in vitro, but unless there are further sources demonstrating a particular interest in this property of P.semilanceata, it would be misleading to mention it in the intro, and would attribute to this finding more significance than is appropriate. While the lead should summarize the article's contents, this sentence certainly does not adequately summarise the "Ecology and habitat" section - we already refer to this section in the lead when we mention habitats and the mushroom's saprotrophic nature.--Pontificalibus (talk) 15:29, 1 September 2011 (UTC)
- Thinking about it some more, I agree. The lead could probably be a paragraph longer too, will work on it soon. Thanks for your note. Sasata (talk) 15:58, 1 September 2011 (UTC)
References in article
editAmong the article's references, the journal article[1] refers to the unfortunate man mistaking Cortinarius rubellus for Psilocybe semilanceata, with drastic consequences. However, it seems much more likely that he was instead hunting Psilocybe cubensis which resembles the Cortinarius much more closely than Psilocybe semilanceata. So the reference is certainly relevant (if only because it mentions Psilocybe semilanceata), but apparently for the wrong reasons. Comments? Fairflow (talk) 19:20, 7 October 2011 (UTC)
- According to Guzman's 1998 "A worldwide geographical distribution of the neurotropic fungi, an analysis and discussion", P. cubensis isn't even found in Austria (where this incident occurred), while P. semilanceata is the most common European hallucinogenic Psilocybe; so if what you're saying was true, the victim was doubly mixed up. Regardless, our guesses about what he may have been looking for are merely conjecture, and on Wikipedia we have to stick to what the sources actually say. Sasata (talk) 02:15, 8 October 2011 (UTC)
- Thanks Sasata, I stand corrected, on two fronts. It's probably clear I'm a novice Wikipedia editor so apologies for any deviation from the guidelines with this comment thread. Fairflow (talk) 11:56, 8 October 2011 (UTC)

Congratulations!
editCongratulations to all the contributors to this featured article. I love the photo. I used to go mushroom hunting as a child so this article does interest me. You deserve a lot of applause, recognition and appreciation. What a wonderful article.
World's most common psilocybin mushrooms in nature ?
editIs it right to have this sentence in the introduction Of the world's psilocybin mushrooms, it is the most common in nature ?
Later on the article we can read : Psilocybe authority Gastón Guzmán, in his 1983 monograph on psilocybin mushrooms, claimed it is the world's most common psychoactive mushroom. Boussole folle (talk) 07:40, 30 October 2015 (UTC)
- How's this? Sasata (talk) 22:09, 29 October 2015 (UTC)
- Looks good. It definitely isn't the world's most common, since Panaeolus cinctulus is a lot more common, and some other Panaeolus, Psilocybe and Gymnopilus species might be up there. Dgrootmyers (talk) 04:38, 30 October 2015 (UTC)
- I've acquired a copy of Guzmán's The Genus Psilocybe : The genus Psilocybe: A Systematic Revision of the Known Species Including the History, Distribution and Chemistry of the Hallucinogenic Species. (ISBN 3-7682-5474-7), and I found absolutely no mention of this claim.
- The closet sentence I've found is "This is one to most common hallucinogenic species of Psilocybe growing in meadows in Europe and in North America (Canada and U.S.A.)". pp. 362
- Do I miss something or there is an imposture somewhere ? Boussole folle (talk) 23:21, 30 October 2015 (UTC)
- Fixed the source per here. Sasata (talk) 00:28, 31 October 2015 (UTC)
- That makes a lot more sense. Dgrootmyers (talk) 23:38, 30 October 2015 (UTC)
- Also, do you have a PDF of that? I have access to it as a series of JPGs, but it's a pain to use. Dgrootmyers (talk) 23:50, 30 October 2015 (UTC)
- I'm sorry I don't have a 'searchable' version either, but good news I've spotted what Bresinsky and Besl read on Guzmán's psilocybe monograph. This is located on chapter The known hallucinogenic fungi and their distribution in the world, from page 43 : P. semilanceata has a widespread distribution; it is known from 17 countries (see table 10)
- Then when you read the chapter, you understand this is most widespread compare to the other species mentioned.
- What do you think about this? Boussole folle (talk) 12:51, 31 October 2015 (UTC)
Phenylethylamine presence in the sporophore
editWhy mention the presence of phenylethylamine in the article introduction before baeocystin ?
Baeocystime is much more present, even psilocin could be more present. Boussole folle (talk) 07:40, 30 October 2015 (UTC)

Common names
editThe article presents the species' common name in North America as being its only common name; in the U.K., at least, it's known as the Magic Mushroom, not as the Liberty Cap. This can be confirmed by reference to most if not all on-line sources. --213.31.16.54 (talk) 21:39, 15 December 2021 (UTC)
- There are 200 species of magic mushrooms, so I think a more descriptive name is better. I can find lots of references to liberty caps in the UK, for example https://theconversation.com/liberty-cap-the-surprising-tale-of-how-europes-magic-mushroom-got-its-name-130668.
