Which mushrooms bruise blue

Psilocybe cubensis - The stems bruise blue or blue -green. This is a hallucinogenic mushroom , but note that not all hallucinogenic mushrooms bruise blue. Can you eat bruised mushrooms? If you notice any bruises or brown and black spots on the mushrooms, throw them in the trash, since they could make you sick. In general, you shouldn't eat fresh mushrooms after 10 days of buying them, although some mushrooms can start to go bad after a few days.

Why do some mushrooms turn blue? The color change is caused by a chemical reaction that occurs when certain compounds in the cell walls of the mushroom are exposed to air. When exposed to air, the variegatic acid in this mushroom is converted to the blue-colored molecule quinone methide. There are many famous blue-bruising mushrooms. How can you tell a mushroom is poisonous? Poisonous mushrooms often have an unpleasant, acrid smell, while benign ones smell refreshingly mushroomlike. You can also get information by cutting off the stem and placing the cap on a piece of paper gill-side down for a few hours to get a spore print.

A white spore print is a telltale sign of an Amanita species. How can you tell if a mushroom is aborted? Re: How to identify an abort. Why do boletes turn blue? The oxygenase enzyme converts the variegatic acid to its quinone methide, which is blue. Interestingly, in many other boletes, in the absence of oxygen, variegatic acid is converted to variegatorubin, which is responsible to the red color found in many members of this group.

What is the strongest hallucinogenic mushroom? Psilocybe azurescens, is by far the strongest magic mushroom species.

The Psilocybe azurescens is first identified and named by Paul Stamets, and the most potent ever found. Do liberty caps turn blue? To be more specific, blue bruising may indicate whether or not a mushroom contains psilocybin and psilocin, the primary chemical compounds responsible for the psychoactive effects of certain mushroom species.

Bruising is common in many different mushrooms. Even the common button mushroom, found in abundance at the local supermarket, can develop bluish-purple bruises when injured. Yet, these bruises are not caused by ruptured blood vessels, like they are in humans and other animals.

Instead, injury can trigger chemical reactions in mushrooms that cause them to change color. The exact cause of the bluing reaction evaded scientists for decades. The first major breakthrough came in , nine years after Albert Hofmann successfully isolated and identified psilocybin. The discovery came from a research team in Ithaca, New York , who observed a bluing reaction in rat brain cells treated with psilocin. Oxidation of the compound triggered the color change, they articulated. Psilocybin often takes the limelight, but the chemical is converted into psychedelic psilocin in the human body.

Once there, the compound can induce brain states that inspire profound and sometimes mystical experiences. In a growing magic mushroom, however, psilocin is found only in trace amounts.

Psilocin is an unstable molecule that breaks down quickly. Psilocybin, in contrast, is more stable and thus found in greater abundance in the fungi.

It took scientists nearly six decades, however, to solve the mushroom mystery. In , German researcher Dirk Hoffmeister and his colleagues identified the source of the bluing reaction psychoactive mushrooms. Picking, handling, or damaging the mushrooms triggers a chemical reaction that activates two enzymes in the mushroom, PsiP and PsiL.

The first enzyme, PsiP, converts psilocybin to psilocin in the mushroom. This is similar to the way in which enzymes in the human liver also catalyze psilocybin to psilocin. In our case, the reaction inspires a psychedelic experience.

The compound is quickly oxidized by the second enzyme, PsiL, rendering the molecule unstable. Not all magic mushrooms bruise blue. You may be surprised to find out that not all psychedelic mushrooms produce psilocin or psilocybin. The psychoactive properties of Amanita muscaria , for example, are caused by the chemicals ibotenic acid and muscimol, not psilocin.

This mushroom species, and related species in the Amanita family, do not bruise blue. Similarly, the bruising reaction varies in different psilocybin-containing species.

Sometimes, a mushroom will bruise just a faint blue, while other times, the bruising will appear very dark and hard to miss. Psilocybin-containing magic mushrooms become less potent the more they bruise.

The more bruising, the more psilocin is converted into other inactive compounds. Several species of psychoactive mushrooms bruise blue. Blue bruising is one of the primary—but far from the only—ways to identify a magic mushroom. Blue bruising is far from the only feature used to identify magic mushrooms. Spore color, gill structure, and the presence of a gelatinous pellicle are other indicators, just to name a few. This guide, however, is not intended to provide comprehensive instruction on mushroom identification.

Yet, without further ado, here are three of the most common mushroom genera associated with blue bruising:. The most famous blue bruising mushrooms belong to the Psilocybe genus, which includes the legendary Psilocybe cubensis. These mushrooms are perhaps the easiest for citizen mycologists to recognize.

Here are three of the most popular psilocybes:. Yet, for the amateur identifier, blue bruising is a hallmark characteristic of psilocybe mushrooms. C Lenz et al , Angew.
