A very common colour, but why?
The colour of fungi is often determined by specific pigments that can perform different functions, such as protection from UV rays, defence against predators or attracting insects to disperse spores. White mushrooms, on the other hand, lack these pigments.
This is no coincidence. The absence of pigments can be advantageous in dark, damp environments, where protection from intense light is not necessary. In addition, white mushrooms can camouflage themselves in their environment, which helps them escape certain predators.
It is also possible that white mushrooms use different chemical mechanisms to defend themselves against pathogens or to attract symbiotic partners. Some white mushrooms have unique bioactive compounds that play a role in their survival, such as triterpenes.
The different types of white mushrooms
White mushrooms encompass a wide variety of species that can be classified according to their edibility and other properties, especially medicinal ones. In this section, we explore both poisonous white mushrooms and some of the best-known edible white mushrooms, highlighting their characteristics and importance.
AGARICUS BISPORUS: the best known of the edible white mushrooms
Agaricus bisporus, or button mushroom, is the most widely consumed mushroom in the world and accounts for a large part of global production, with millions of tonnes cultivated each year. Native to the grasslands of Europe and North America, it was first cultivated in France in the 17th century, during the reign of Louis XIV, before spreading worldwide.
Its popularity is explained by its ease of cultivation indoors throughout the year and its great versatility in the kitchen. It can be eaten raw in salads or cooked in soups, sauces, stir-fries and as a pizza topping. Agaricus bisporus is prized for its flavour and nutritional richness in protein, fibre, B vitamins and vitamin D, making it one of the most interesting edible white mushrooms from a nutritional point of view.
Poisonous white mushrooms
Amanita phalloides: the super-toxic mushroom!
Don't be fooled by its ordinary appearance. Often known as the “death cap”, Amanita phalloides is one of the most toxic fungi in the world. This inconspicuous white mushroom contains potentially lethal toxins. It has been responsible for numerous accidental poisonings, as it can be mistaken for very common edible species, including some similar-looking edible white mushrooms.
It contains toxins called amatoxins, which inhibit protein synthesis and can cause severe liver and kidney damage, often fatal if left untreated. It usually grows in deciduous forests, particularly under oak and beech trees. Despite its toxicity, it has played a key role in research to better understand the mechanisms of fungal poisons.
Amanita virosa: from the same family and with the same devastating power
Among the toxic species we also find Amanita virosa, known as the ‘destroying angel’ or ‘stinking amanita’, a highly toxic basidiomycete fungus of the Amanitaceae family. This deadly fungus is characterised by its completely white appearance, with a cap up to 10 cm in diameter, often irregular and sometimes with a small central protuberance.
It appears from mid-summer to autumn throughout Europe, including Spain. It gives off a slight odour that can intensify and resemble that of wilted roses. It is often confused with other species of mushrooms, both edible and poisonous. Among its best-known ‘doubles’ are Amanita verna and Amanita phalloides, both toxic, as well as several edible species of the genus Agaricus.
Entoloma lividum
Last notable example among toxic mushrooms, Entoloma, commonly known as livid entoloma or false miller, is a toxic species belonging to the genus Entoloma. It is characterised by its fleshy, large appearance, with a whitish to beige cap that can reach up to 20 cm in diameter. The mushroom has a distinctive flour-like smell, and its gills turn from yellow to pink as it matures.
Like the others, Entoloma lividum is particularly dangerous because of its resemblance to edible species. Consumption can cause severe gastrointestinal symptoms, such as acute diarrhoea and violent vomiting, which generally appear 3 to 8 hours after ingestion.
Medicinal White Mushrooms
Pleurotus ostreatus
Fortunately, in addition to the button mushroom, there are also many edible white mushrooms that can offer beneficial properties. Pleurotus ostreatus, or oyster mushroom, is one of them.
This basidiomycete fungus belongs to the Pleurotaceae family. It is easily recognised by its oyster shell-shaped cap, usually grey to dark brown, and its firm white flesh. It is highly valued for its flavour and is frequently used in Asian cuisine, especially in soups and stir-fries.
Beyond its culinary uses, Pleurotus ostreatus is recognised for its medicinal properties, thanks to its richness in bioactive compounds such as terpenoids and polysaccharides.
Coprinus comatus
Coprinus comatus is also a basidiomycete fungus, recognised by the shaggy cuticle that covers almost the entire stem. It grows mainly in areas rich in organic matter, such as lawns, gardens and roadsides.
Considered an excellent edible mushroom when young and completely white, it should be consumed quickly after harvesting. Coprinus comatus is mainly harvested in autumn.
Lion’s Mane or Hericium erinaceus: a truly remarkable mushroom
Lion’s Mane (Hericium erinaceus), also known as yamabushitake or hou tou gu, is a large, white, shaggy mushroom that strikingly resembles a lion’s mane.
It is used for both culinary and medicinal purposes, especially in Asian countries such as China, India, Japan and Korea. Hericium contains bioactive compounds, including hericenones and erinacines, whose activity has been shown to potentially stimulate the growth of brain cells and may have neuroprotective properties.
These compounds are believed to support cognitive function, improve mental clarity and enhance concentration. In addition, Lion’s Mane contains beta-1,3/1,6-glucans, which may help support the immune system. The mushroom is often consumed as a supplement in various forms, such as concentrated extracts.

White: a multifaceted colour in mycology
The world of edible white mushrooms is captivating in many ways. Their tones enhance our landscapes, and their role in ecosystems and health is crucial. Some mushrooms, although visually appealing, can be toxic, while others, such as Lion’s Mane, offer remarkable medicinal virtues, illustrating the fascinating and beneficial duality of nature.
