Mushrooms are mysterious and compelling, with their otherworldly appearance, symbiotic relationship with forest flora, and ability to either nourish or cause harm, depending on the species. In Ireland, there are an estimated 7,000 species of mushroom-producing fungi, with at least 2,500 varieties of mushrooms, including about eight magic varieties that can cause hallucinations. Only about 5% of these are edible, and even then, many are not particularly tasty or easy to prepare. Mushroom foraging has gained popularity in Ireland, but it is crucial to be able to distinguish between edible and poisonous mushrooms to avoid accidental poisoning.

What You'll Learn
There are about 20 common edible species
There are about 20 common edible mushroom species in Ireland. However, there are an estimated 7,000 species of mushroom-producing fungi in the country, with at least 2,500 varieties of mushrooms in total. This means that only about 5% of the mushroom species in Ireland are edible. Many mushrooms are toxic and can cause significant harm to the liver and kidneys if ingested.
It is important to be able to distinguish between edible and poisonous mushrooms. While some poisonous mushrooms bear a striking resemblance to edible ones, others can be easily identified as toxic. For instance, there are about 30 species of poisonous mushrooms in Ireland that can cause symptoms ranging from an upset stomach to more serious, life-threatening symptoms. Some of these poisonous mushrooms can even cause hallucinations, similar to the effects of illegal drugs or alcohol.
To avoid accidental poisoning, it is recommended to never consume a mushroom unless you are absolutely certain of its identity. This is especially important when children are involved, as they are naturally curious and may mistake a poisonous mushroom for something safe to eat. The National Poisons Information Centre of Ireland provides urgent advice and can be contacted if you suspect someone has ingested a wild mushroom.
While mushroom foraging has gained popularity in Ireland, it is important to exercise caution. Unlike in Scandinavia and continental Europe, where people are accustomed to celebrating the arrival of mushroom season and venturing out on foraging excursions, the Irish tend to view wild mushrooms with suspicion due to the fear of poisoning. Nevertheless, with proper knowledge and identification skills, it is possible to safely enjoy the edible mushrooms that Ireland has to offer.

7,000 species of mushroom-producing fungi grow in Ireland
Ireland is home to an estimated 7,000 species of mushroom-producing fungi. However, only about 5% of these are edible, and even then, some are too chewy, difficult to prepare, or not very tasty. This equates to far more than 20 edible species, but it is still important to be able to identify them correctly to avoid poisoning. Mushrooms have been harvested in Ireland as food and medicine since ancient times, but it takes skill to learn about the harvesting and preparation of both medicinal and nutritional fungi.
Many mushrooms are toxic and can cause serious harm to the liver and kidneys if ingested. It is advised that people should never eat a fungus that they cannot positively identify as an edible species. Even then, some edible mushrooms can cause an upset stomach, as one forager found out after consuming a generous helping of 'Chicken of the Woods'.
Mushrooms are the fruiting bodies of fungi, producing and dispersing spores at certain times of the year. They are often found growing on decaying tree stumps, fallen trees, or in fields. They can grow almost anywhere if the conditions are right, and they particularly like warm and wet conditions. In Ireland, the mushroom-growing season is usually from spring until late autumn.
There are approximately 30 species of poisonous mushrooms in Ireland, which can cause symptoms ranging from an upset stomach to more serious, life-threatening symptoms.

2,500 species in total, including 8 'magic' varieties
There are an estimated 2,500 species of mushrooms in Ireland, including eight "magic" varieties. Mushrooms are mysterious and compelling, with their otherworldly appearance and symbiotic relationship with forest flora. They are the fruiting bodies of fungi, producing and dispersing spores to increase the odds of reproductive success. Fungi, of which mushrooms are one small part, are the largest living organisms on our planet. Their microscopic filaments, or hyphae, can spread across thousands of kilometres underground and can live for hundreds, even thousands, of years.
While some mushrooms are prized for their nutritional and medicinal qualities, many are toxic and can cause significant harm if ingested. It is estimated that only about 5% of Ireland's 2,500 mushroom species are edible, and even then, some are too chewy or difficult to prepare to be considered worthwhile. It is not especially difficult to learn to identify a handful of edible mushrooms, but it does take some skill.
In Ireland, wild mushrooms are often treated with suspicion due to the possibility of poisoning. This is in contrast to Scandinavia and continental Europe, where people are more accustomed to celebrating the arrival of mushroom season and venturing out on foraging excursions. The greatest concentration of mushrooms in Ireland is in forests, where they have a natural relationship with trees, producing nitrogen and oxygen for them while receiving proteins in return.
Gathering wild mushrooms has become a popular pastime in Ireland, but it is important to exercise caution. It is not always easy to identify fungi, and cases of accidental mushroom poisoning occur each year. To stay safe, it is advisable to never eat a mushroom until you are certain of its identity.

The Fly Agaric is one such poisonous mushroom, easily recognisable and causing nausea, vomiting, muscle incoordination, dizziness, and drowsiness.
