Oyster mushrooms, scientifically known as Pleurotus spp., are considered a delicacy due to their subtle savoury flavour and meaty texture. Oyster mushrooms are widely distributed and can be found in tropical rainforests, subtropical forests, and desert landscapes. They are also easy to grow and can be cultivated on straw, agricultural waste, wood, and other materials. There are over 200 species of oyster mushrooms, with six types of true oyster mushrooms and one honorary mushroom. The most common types include Pearl, Blue, Golden, Pink, Phoenix, Elm, White, Grey, and King Oyster mushrooms.

Pearl oyster mushrooms: the most common variety, with a slightly sweet, woody flavour
Oyster mushrooms, scientifically known as Pleurotus spp., are delicious and full of flavour. They are also considered a medicinal food. There are around 202 edible species within the Pleurotus family, with Pearl oysters being the most common in North America.
Pearl oyster mushrooms (Pleurotus ostreatus) are the most common variety of oyster mushrooms. They are mild and tender, with a slightly sweet, woody flavour. They are white or light brownish-grey in colour, with large visible gills of the same colour, and thick, short stems. They are excellent for adding to dishes to enhance the flavours of the other ingredients. Most oyster mushroom recipes use pearl oysters.
Pearl oyster mushrooms are also known as tree oyster mushrooms. They are an edible mushroom prized for their subtly savoury flavour and meaty texture. They can be found growing wild on and near trees in temperate and subtropical forests and are also grown commercially around the world. They are eaten in many different countries but are particularly popular in Chinese, Japanese, and Korean cuisine.
Pearl oyster mushrooms are similar in flavour to Phoenix oyster mushrooms, which have smaller, paler caps and longer stems. Phoenix oysters prefer warmer weather and tend to grow in late summer. They are also similar in flavour to Black Oyster mushrooms, which may have a slight anise flavour.
Oyster mushrooms are one of the simplest varieties of mushrooms to grow at home since they will grow on a wide variety of growing mediums. They are also one of the fastest-growing mushrooms, with a wide variety of potential substrates and tolerance to growing conditions. They are saprotrophic, which means they feed on dead material, and they prefer to grow on deciduous hardwood trees like aspen or beech.

Blue oyster mushrooms: named for the blue colour of their caps when they first bloom
Oyster mushrooms, scientifically categorised as Pleurotus sp, are a type of edible fungi. They are one of the most widely consumed mushrooms in the world and are commercially cultivated and sold. Oyster mushrooms have a fan- or ear-like shape that somewhat resembles their sea-dwelling namesakes. They are typically light grey or greyish-brown in colour, but they also come in several other colours, including yellow and pink.
There are several types of oyster mushrooms, all of which are edible and belong to the Pleurotus genus. One such variety is the blue oyster mushroom, named for the blue colour of their caps when they first bloom. The caps of blue oyster mushrooms start as dark blue and gradually lighten to a blue-grey shade as they mature. They have slender white gills under the cap, which contain a high spore content. Blue oyster mushrooms are primarily found in the northern hemisphere and are commercially favoured by mushroom growers for their unusual colouring, ease of growth, and fast colonisation.
Blue oyster mushrooms are a fun variety to grow at home. They grow fast and are incredibly versatile, as they can be grown on coffee grounds, waste paper, sugar cane, grass, and many other waste industrial products. They are also suitable for growing outdoors, producing much larger fruits with relatively low maintenance. Blue oyster mushrooms have a spongy, dense, and slightly chewy texture, and a mild, earthy, and savoury flavour. They are commonly added to Asian cuisines or stews because they do not lose their shape in soup and can be used as meat replacements.
In addition to blue oyster mushrooms, there are several other varieties, including pearl oyster, pink oyster, flamingo oyster, phoenix oyster, king oyster, and elm oyster mushrooms. Each variety has its own unique characteristics, such as colour, shape, texture, and flavour. Oyster mushrooms, in general, are a good source of fibre and are believed to offer several health benefits, including lowering cholesterol and boosting the immune system.

Pink oyster mushrooms: vivid pink colour, native to the tropics, with a stronger woody smell
Oyster mushrooms, scientifically known as Pleurotus sp, are edible fungi with a fan- or ear-like shape that resembles their sea-dwelling namesakes. They are typically light grey or greyish-brown but also come in other colours like yellow, pink, blue, and even golden. Oyster mushrooms have a subtly savoury, mild, and woody flavour with a hint of anise and a meaty texture. They are widely consumed and can be found growing wild or commercially cultivated worldwide, particularly in Chinese, Japanese, and Korean cuisine.
One variety of oyster mushrooms is the pink oyster mushroom, also known as the flamingo oyster or Pleurotus djamor. It is a vivid pink colour with a ruffled appearance and is native to the tropics, specifically Indonesia. Pink oyster mushrooms have a stronger woody smell and a tougher texture compared to other oyster mushrooms. They grow on hardwood trees and are available in the spring through the fall.
Pink oyster mushrooms are small to medium in size, with caps averaging 2-5 centimetres in diameter and short or non-existent stems. They have a pungent, seafood-like aroma when raw and develop a mild, woody flavour when cooked. The pink colour fades once cooked, which is unfortunate as it is an attractive feature of this variety.
Pink oyster mushrooms are native to Indonesia and were first described in the late 17th century by botanist Georg Eberhard Rumphius. They were initially named Agaricus djamor in 1821 but were later reclassified under the genus Pleurotus in 1959 by Karel Bernard Boedijn. Today, they can be found in local markets and are cultivated in warm, tropical climates worldwide, including Mexico, Brazil, Thailand, Cambodia, and many other regions.
Pink oyster mushrooms can be cultivated using liquid culture syringes, which are injected directly into a sterilised substrate. They thrive in warm temperatures, producing a fan-like fruiting body. They are ideal for substrates such as rye grain, pasteurised straw, or paper.

Yellow oyster mushrooms: delicate, with small caps, and a beautiful yellow colour
Oyster mushrooms, scientifically known as Pleurotus sp, are edible fungi. They are one of the most widely consumed mushrooms in the world and are commercially cultivated. Oyster mushrooms come in several varieties, each with distinct characteristics. There are six types of true oyster mushrooms, along with one similar mushroom that is sometimes considered an honorary member of the group.
Yellow Oyster Mushrooms
Yellow oyster mushrooms, also known as golden oysters, are a beautiful variety with delicate, small caps in bright yellow or golden yellow hues. They are native to subtropical regions of Asia, particularly the hardwood forests of northern China, Japan, and eastern Russia. Yellow oyster mushrooms are now also found in Europe and North America, believed to be due to the spread of spores from cultivated mushrooms.
Yellow oyster mushrooms are prized for their beauty, flavour, and health benefits. They are known to have complex flavours and a slightly chewy texture when cooked. In terms of nutrition, they are high in protein and fibre, low in fat, and a good source of potassium, vitamins, minerals, and essential amino acids. Studies suggest that compounds in yellow oyster mushrooms may aid in weight management, cholesterol management, and exhibit antimicrobial and antioxidant properties.
Yellow oyster mushrooms are easy to grow and are a popular choice for home cultivators. They grow quickly and fruit heavily, forming beautiful yellow clusters or "bouquets". However, their delicate nature and short shelf life make them less suitable for commercial production and long-distance transportation. When harvesting yellow oyster mushrooms, it is important to use a sharp knife to remove the entire cluster at the base, as their thin, fragile caps break easily.
Yellow oyster mushrooms are versatile in the kitchen and pair well with various ingredients. They are commonly used in Asian cuisine and can be sautéed, added to salads, or used as a substitute for bacon bits due to their crispy texture.

King oyster mushrooms: the least similar in appearance, with a thicker, meatier stem
Oyster mushrooms, scientifically known as Pleurotus spp., are edible fungi with a fan- or ear-like shape that resembles their sea-dwelling namesakes. They are one of the most widely consumed mushrooms in the world and are known for their simple cultivation process. Oyster mushrooms were first officially documented in 1775 by Nikolaus Joseph Freiherr von Jacquin, a Dutch naturalist.
While there are over 200 species of Pleurotus, there are six types of true oyster mushrooms, each with distinct characteristics. Pearl oyster (Pleurotus ostreatus) is the most common variety, particularly in North America. It has a slightly sweet, woody flavour and is known for its clean flavour and delicate, chewy texture. Blue oyster (Pleurotus columbinus) is named for the blue hue of its caps when they first bloom, later fading to grey. Yellow or golden oyster (Pleurotus citrinopileatus) is a delicate variety with small caps sporting a beautiful yellow colour. Pink oyster (Pleurotus djamor), also known as the flamingo oyster, is a vivid pink mushroom native to the tropics with a ruffled appearance and a stronger woody smell. Phoenix oyster (Pleurotus pulmonarius) is similar in flavour to the pearl oyster but has a smaller, paler cap and a longer stem. It is a popular variety for home cultivation due to its versatility in various dishes and ease of cooking.
Among the different types of oyster mushrooms, the King oyster (Pleurotus eryngii) stands out for its unique appearance. It is much larger than other varieties, with a thicker, meatier stem and tan-coloured caps. Unlike most oyster mushrooms, which grow in clusters, King oysters grow individually. They have a savoury, umami flavour similar to scallops and are not native to the US.
The elm oyster mushroom (Hypsizygus ulmarius) is another variety worth mentioning, although it is not a true Pleurotus species. It grows high up on elm trees in dense clusters of large caps that can range from white to tan in colour. Elm oyster mushrooms have the potential for indoor growing and are edible, although their flavour differs from that of typical oyster mushrooms.
