- Subject: Mushroom Identification
-
- I've decided to go shroom picking this year and recently posted a request
- for information to a.d, this has met with a lot of response (from the UK),
- it seems people are a bit vague on what it looks like, and where to find
- them.
-
- I've been looking through books and condensed all the relevant info
- into this file (also a couple of gifs).
-
- The two species I have concentrated on are Psilocybe Semilanceata (Liberty
- Caps) and Amanita Muscaria (Fly Agaric). I have been looking for the first
- (I'm not too bothered about the second, after reading a few posts about it
- in a.d, it sounds a little too heavy, pos. dangerous), the literature seems
- to have the concensus that it is harmless (except for the hallucinogenic
- properties :) ).
-
- I hope this helps ....

- Poisonous Fungi
- Some species affect the central nervous system causing hallucinations and
- sometimes leading to coma. In the case of muscimol poisoning, also caused
- by the Fly Agaric (Amanita muscaria) and by others such as The Panther
- (A. pantherina), the symptoms consist mainly of drowsiness but can be more
- serious. Some of the Psiocybe species, on the other hand, cause visual
- hallucinations within 20 minutes of ingestion. Such mushrooms are sometimes
- deliberately ingested for recreational purposesalthough the legality of such
- actions varies between countries.
-
- Psilocybe Semilanceata (Stropharia (Strophariaceae)) - Liberty Cap.
- A well-known species, owing to its reputation as a "magic mushroom"
- Cap: 3/8-5/8 in(1-1.5cm) in diameter, narrowly conical with a central,
- pointed projection, not expandinhg, pale yellowish brown, drying
- to almost white, smooth, sticky, with a darker striated margin.
- Gills: adnate, grey-brown to blackish brown, broad and crowded.
- Stem: 2-3 X 1/8 in (5-8X0.2-03 cm), slender, cylindrical, paler than the
- cap and often bruising bluish green towards the base.
- Flesh: thin, firm.
- Spore deposit: purplish black.
- Habitat: very common, solitary or in very large numbers, in open grassland.
- Edibility: toxic, causing psychotropic poisoning, and consequently has been
- used as a hallucinogen.
- Season: Autumn
- Similar species: There are numerous species of Psilocybe, and many are small
- and similar in appearance. The Bluing Psilocybe (P. cyanescens)
- lacks a point on the cap, while P. fimetaria grows on dung; both
- poisonous.
-
- Amanita Muscaria (Amanita (Amanitaceae)) - Fly Agaric.
- Perhaps the best-known wild mushroom, having a large, scarlet cap with small
- white scales, and a membranous ring on the stem.
- Cap: 2-9 in (5-25 cm) in diameter, strongly rounded the expanding to flat
- and platelike, moist and shiny, with concentric rings of small white
- scales which may become washed away by the rain.
- Gills: free, white to pale yellow, broad and rounded.
- Stem: 4-9 X 3/8-1 in (10-25 X 1-2.5 cm), tall, cylindrical with as swollen
- base.
- Flesh: thick, white, yellowish under cap cuticle.
- Spore deposit: white.
- Habitat: in small groups, under pine or birch.
- Edibility: poisonous, containing both sweat-inducing and mild hallucinogenic
- poisons, which can cause delerium and coma.
- Season: Autumn
- Similar species: The variety regalis is yellowish brown with yellow scales,
- and in North America, the variety formosa is orange-yellow; both
- poisonous.

- Mushroom Poisoning - The nerve poisons.
- Apart from the cell poisons, the most dangerous species are those which
- contain substances that affect the nervous system. Strictly speaking the
- hallucinogenic species also affect the nervous system, but the disturbances
- in this case are usually restricted to sensory distortion. Mushrooms
- containing nerve poisons can cause more serious symptoms such as convulsions,
- irregular breathing and, in severe cases, death through heart failure. Two
- types of toxin have been implicated in this type of poisoning - muscarine
- and ibotenic acid.
-
- Hallucinogenic mushrooms.
- The principal toxins in Amanita muscaria have now been identified as ibotenic
- acid, and the closely related compound, muscimol. The Panther Cap (A.
- pantherina) causes similar symptoms, also attributed to these poisons but
- while this latter species is rightly regarded as dangerous, the status of
- Fly Agaric as a deadly mushroom has been questioned. It has traditionally
- been used as a ritual halluginogen in certain cultures and attitudes to this
- mushroom would appear to be more to do with cultural background than with any
- scientific assessment of it's toxicity.
-
- Psilocybe semilanceata - Liberty Caps.
- This small fungus was given the name Liberty Caps because the shape of its
- cap is like that adopted as the symbol of the first French Republic. It
- contains the hallucinatory drug psilocybin, and may have been tried by those
- seeking new drug experiences. In a recent English court case it was judged
- not to be an offence to possess the fruiting bodies of this species.
- Cap: pale clay colour, becoming yellowish-olive or dingy brown. 0.5-1cm in
- diameter, up to 2cm high. Acutely conical, often with a sharp point, never
- exapnding. Margin inrolled at first, slightly striate. Cutcle slimy,
- peeling in wet weather. Flesh membranous, white.
- Gills: finally purplish brown with white edges, adnate, narrow, crowded.
- Stipe: slender, usually wavy, up to 7.5 cm long. Whitish at the top, pale
- clay lower down. Smooth with remnants of viel in young specimins.
- Flesh: pliant, tough.
- Spores: purple-brown in mass, ellipsoid, smooth, with a germ pore, average
- size 13.0 X 7.8 microns.
- Habitat and distribution.
- Grows gregariously, often in troops, among grass, in fields, pastures, heaths
- and along roadsides where animals have grazed. Frequent to common in Europe
- and North America, it also grows in Australia.
- Occurrence: August to November.
- Culinary properties: It is said to be poisonous when raw, even fatal is eaten
- by children. Harmless when cooked.

-
- Poisonous fungi and the symptoms of poisoning.
-
- Psychotropic poisoning involves serious cases characterized by the irritation
- of brain tissue. For a long time the intoxication caused by the Fly Agaric
- was the only form of mushroom poisoning accompanied by psychic disturbances.
- It was not before the 1950s that other so-called cult fungi, formally used in
- religious ceremonies and rites, were identified; their ingestion leads to
- different manifestations of psychic disturbance. Two types of psychotropic
- poisoning are distinguished: psychotonic poisoning caused by the so-called
- mycoatropine, and psychodysleptic poisoning caused by psilocybine.
-
- In Europe, poisoning by mycoatropine is caused by three Amanita species.
- Most common are cases of poisoning after eating the Panther Cap, less
- frequent are those caused by the Fly Agaric, and practically unknown is
- poisoning by A. regalis. The poisonous content principles of these amanitas
- have not yet been exactly identified, and this is why the designation
- 'mycoatrophine poisoning', though inadequate, is still used nowadays.
-
- The course of poisoning caused by all the three species is substantially the
- same: nausea is experienced between half an hour and three hours after
- consumption, accompanied by vomiting, headache, quickened heartbeat, and a
- persistent dilation of pupils occasionally leading to vision disturbances.
- Often the condition of the affected person resembles alchoholic intoxication:
- the patient becomes talkative, shouts obscenities, sometimes laughs or weeps,
- strikes himself and keeps on running to and fro. The states of excitement
- may be dangerous for the sick person and must therefore be mitigated.
- Subsequently the patient faints, recovers from time to time, hallucinates,
- screams, defends himself against invisable danger, etc, but finally falls
- into a profound sleep from which he usually awakens into a normal state,
- without remembering his previous behaviour. This poisoning comes to it's
- fortunate end on the second or third day. First aid consists in the
- stimulation of vomiting and in taking the patient to hospital; he must be
- given neither milk nor alchohol. The treatment starts with a stomach rinse,
- the excitement is controlled by remidies of the cholpromazine type,
- physostigmne (never atropine!) is administered as an antidote against
- mycoatropine.
-
- Psilocybine poisoning occurs after consuming some species of the genus
- Psilocybe, or fungi belonging to related genera about which, nowadays,
- abundant literature is available. These fungi are distributed mostly in
- Mexico and in some Central American countries. They contain so-called
- hallucinogenic substances thanks to which they had long been used in
- religious rituals and were kept secret until the twentieth century. Their
- research is due to the efforts of the American ethnographers Mr and Mrs
- Wasson who succeeded in aquiring hallucunogenous fungi, which they studied
- and identified with the help of mycologists. Chemical analysis of these
- fungi were carried out, and it was even possible to cultivate some of them.
- The effecttive substance was finally produced artificially, whereby its
- experimental testing on volunteers and its application for therapeutic
- purposes was made possible.
-
- Fungi containing hallucinogenic substances generally produce small,
- inconspicuous fruit bodies growing on dung or excrements. They belong to the
- genera Psilocybe, Panaeolus, Panaelina and Stropharia. The amount of
- effective substances in the fruit bodies is variable, particularly in the
- European representatives of the mentioned genera whose effect is
- substantially smaller in comparison with the Mexican species.
-
- The psychic symptoms following the ingestion of halluginogenic fungi are
- extremely varied. In some individuals they manifest themselves as euphoria,
- in others as sight disorders and hallucinations; saometimes they assume the
- form of the kaleidoscopic effect involving the duplication of objects in
- inappropriate colours; still other persons, on the contrary, feel anxiety
- and fear, suffer from terrifying delusions, and these states may lead to
- delirium and suicide attempts. Thanks to the lower content of effective
- substances, the European fungi evoke much milder symptoms.
-
- Hallucinogenic fungi contain four active substances; psilocybine, psilocine,
- baeocystine, and norbaeocystine. Psilocine is considered the main bearer of
- halluginogenic proprties. However, poisoning by these fungi is exceptional,
- and there is no danger of misusing European hallucinogenic fungi for
- intentional intoxication.
-
-
- Psilocybe semilanceata (Liberty Cap)
-
- The genus Psilocybe, as well as the related genera Panaeolus and Stropharia,
- have become better known - and especially more popular - following the
- discovery of hallucinogenic substances obtained from numerous Mexican species
- of Psilocybe. Further analyses have also shown that some European species of
- the genus Psilocybe also contain substances with hallucinogenic effects,
- even though in substantially smaller quantities so that the symptoms
- following their ingestion are much milder.
-
- Psilocybe semilanceata is a very small fungus which easily escapes attention.
- Its cap is 1-2 cm high, always higher than it is wide, markedly and
- persistently lanceolate-pointed or narrowly conical, often with an abruptly
- projecting point, thin-fleshed, hygrophanous, shiny or sticky, dark olive
- grey-brown or yellow-brown when moist, in dry conditions leathery yellow,
- smooth, glabrous, with greenish spots. The stipe is very long, only 2-3mm
- thick, firm and tough, tortuous, pallid or brownish, with a silky sheen,
- often blue-green at the base, attached to the substrate by a bluish green
- mycelium. The gills are broadly adnate, olive grey or brownish with a lilac
- tinge, then red-brown to black-brown, with white ciliate edges. The gill
- edges harbour numerous cheilocystidia. The flesh has no specifiec odour nor
- taste. The spore print is dark brown.
- P. semilanceata grows in grass tufts on pasturelands and forest tracks from
- August to October. It is not particularly abundant and appears more commonly
- in upland regions. It is inedible because of the halluginogenic substances
- it contains.
-
- 1. Amanita muscaria (Fly Agaric)
- The Fly Agaric has been known as a poisonous species since ancient times.
- Its toxicity is mainly due to the presence of mycoatropine which causes
- disorders of mental activity. The content of another poisonous principle,
- muscarine, is relatively small. Recently the identity of the Fly Agaric with
- the drug called 'soma', venerated by the most ancient Aryan tribes in the
- time of migrating to and settling in the mountains of Afghanistan, has been
- established. The migration of peoples contributed to the further spreading
- of the Fly Agaric cult. Particularly remarkable is the Siberian cult of the
- Fly Agaric: people were drinking fruit-body decoctions, chewing dry
- toadstools and washing them down with cold water; or they would prepare a
- beverage from a micture of the toadstool and leaves of the Bog Whortleberry
- nad Salix angustifolia. Since the effective substance is secreted with
- urine, they even drank the urine of intoxicated persons.
-
- The symptoms of swallowing include vomiting, headache, accelerated heartbeat,
- dilation of pupils; often a state similar to alcoholic intoxication and
- hallucinations set in, and finally the poisoned person awakes in the morning
- in a normal condition, without remembering his or her previous behaviour.
-
- 2. Amanita regalis, growing in upland spruce stands, is distinguished by a
- yellowish-brown cap, a yellowish stipe and similarly coloured remnants of the
- outer veil on the cap, and by a ring. It seems to be as poisonous as the
- Fly agaric.
