Pleurotus pulmonarius, commonly known as the Indian oyster, Italian oyster, phoenix mushroom, or the lung oyster, is a mushroom very similar to Pleurotus ostreatus , the pearl oyster, but with a few noticeable differences. The caps of pulmonarius are much paler and smaller than ostreatus and develops more of a stem. P. pulmonarius also prefers warmer weather than ostreatus and will appear later in the summer. Otherwise, the taste and cultivation of the two species is generally described as largely the same. [1] Another similar species, North America's Pleurotus populinus , is restricted to growing on aspen and cottonwood.
Pleurotus pulmonarius is widespread in temperate and subtropical forests throughout the world. In the eastern United States, this species is generally found on hardwoods while in the west it is commonly found on conifers. [1]
Pleurotus pulmonarius is the most cultivated oyster mushroom (Pleurotus) species in Europe and North America. The most popular varieties for cultivation are the warm weather varieties, often marketed by spawn manufacturers and cultivators under the incorrect name "Pleurotus sajor-caju". The real Pleurotus sajor-caju (Fr.) Singer is in fact a separate species of mushroom, which was returned to the genus Lentinus by Pegler (1975), and is now called Lentinus sajor-caju (Fr.) Fries. [1]
Pleurotus pulmonarius is commercially cultivated in New Zealand, [3] and is sometimes sold as "Oyster mushrooms". [4] The archetypal oyster mushroom, Pleurotus ostreatus , cannot be imported into New Zealand due to perceived risks to their forestry industry. [5]
The cultivation of Pleurotus pulmonarius is very similar to how one would cultivate other types of Pleurotus species like P. ostreatus by transferring mycelium from a petri plate onto grain and then transferring the grain spawn after the mycelium colonizes it to substrates of straw, wood chips, sawdust, cardboard, coffee grounds, and other cellulose-based substrates.

Several studies done on animals and in vitro suggest P. pulmonarius and its extracts may have possible medicinal applications for a wide range of conditions.
A polysaccharide called β-D-Glucan from P. pulmonarius reduces sensitivity to pain in mice, [6] and could be an "attractive" basis for new analgesic medications. [7] In a different study on mice, a glucan from P. pulmonarius showed potent anti-inflammatory and analgesic properties. [8] A methanol extract of P. pulmonarius displayed anti-inflammatory and antitumor activity comparable to the standard reference drugs diclofenac and cisplatin, respectively. [9]
A 2010 study concluded that extracts of P. pulmonarius may slow the proliferation of cancer cells with high galectin-3 levels, while at the same time downregulate tumour cell adherence –which is directly related to the progression and spread of cancer. [10] Extracts of P. pulmonarius added to the diet of mice delayed carcinogenesis, suggesting that these extracts may be useful as an adjuvant to cancer therapies. [11]
An orally administered hot water extract of P. pulmonarius had a significant antihyperglycemic effect, halted the progression of diabetes, and reduced the mortality of alloxan induced diabetic mice by approximately 50%. It showed a synergistic effect with the antidiabetic drug glibenclamide, supporting the possibility of effective combination therapy of glibenclamide and P. pulmonarius for diabetes. [12]
Pleurotus pulmonarius may be effective in the treatment of hay fever by inhibiting the release of histamine. Powdered P. pulmonarius mushrooms caused a significant reduction in sneezing and nasal rubbing when fed in water to sensitized mice, although the effect gradually builds up over a matter of weeks. When they were given 500 mg/kg a day, a significant effect was observed after two weeks, and it was four weeks before a significant change was observed at 200 mg/kg. [13]
Extracts of P. pulmonarius attenuated the development of acute colitis in a mouse model, suggesting a possible clinical use in the treatment of colitis. [14] A further study by the same authors concluded that the extracts also inhibit colon cancer formation associated with colitis in mice. [15]
Extracts of P. pulmonarius have antimicrobial properties and exhibit antioxidant activity in vitro. [16]
Pleurotus ostreatus is very similar, as is North America's Pleurotus populinus , which is restricted to growing on aspen and cottonwood (genus Populus ). [2] It may resemble a clitocybe, some of which are poisonous, when growing on the top of wood. [2]
Lovastatin, sold under the brand name Mevacor among others, is a statin medication, to treat high blood cholesterol and reduce the risk of cardiovascular disease. Its use is recommended together with lifestyle changes. It is taken by mouth.
Pleurotus ostreatus, the oyster mushroom, oyster fungus, hiratake, or pearl oyster mushroom is a common edible mushroom. It is one of the more commonly sought wild mushrooms, though it can also be cultivated on straw and other media.
Schizophyllan is a neutral extracellular polysaccharide produced by the fungus Schizophyllum commune. Schizophyllan is a β-1,3 beta-glucan with β-1,6 branching. Schizophyllan is also known as sizofiran.
Pleurotus eryngii is an edible mushroom native to Mediterranean regions of Europe, the Middle East, and North Africa, but also grown in many parts of Asia.
Pleurotus is a genus of gilled mushrooms which includes one of the most widely eaten mushrooms, P. ostreatus. Species of Pleurotus may be called oyster, abalone, or tree mushrooms, and are some of the most commonly cultivated edible mushrooms in the world. Pleurotus fungi have also been used in mycoremediation of pollutants, such as petroleum and polycyclic aromatic hydrocarbons.
A glucan is a polysaccharide derived from D-glucose, linked by glycosidic bonds. Glucans are noted in two forms: alpha glucans and beta glucans. Many beta-glucans are medically important. They represent a drug target for antifungal medications of the echinocandin class.
Hericium erinaceus is an edible mushroom belonging to the tooth fungus group. Native to North America, Europe, and Asia, it can be identified by its long spines, occurrence on hardwoods, and tendency to grow a single clump of dangling spines. The fruit bodies can be harvested for culinary use.
AHCC is an alpha-glucan rich nutritional supplement produced from shiitake. The product is a subject of research as a potential anti-cancer agent. AHCC is a popular alternative medicine in Japan.
Lentinan is a polysaccharide isolated from the fruit body of shiitake mushroom.
Pleuran is an insoluble polysaccharide, isolated from Pleurotus ostreatus.
Pleurotus citrinopileatus, the golden oyster mushroom, is an edible gilled fungus. Native to eastern Russia, northern China, and Japan, the golden oyster mushroom is very closely related to P. cornucopiae of Europe, with some authors considering them to be at the rank of subspecies. In far eastern Russia, P. citrinopileatus, they are called iI'mak, is one of the most popular wild edible mushrooms.
Pleurotus populinus, the aspen oyster mushroom, is a gilled fungus native to North America. It is found on dead wood of aspen and cottonwood trees. Although morphologically similar to Pleurotus ostreatus and Pleurotus pulmonarius, it has been shown to be a distinct species incapable of cross-breeding. P. populinus is reported to be edible. Unlike P. ostreatus, which fruits in the autumn and winter, P. populinus fruits in late spring and summer.
Lentinus sajor-caju is a species of saprophytic mushroom.
Pleurotus sajor-caju may refer to:
Pleurotus cornucopiae is a species of edible fungus in the genus Pleurotus, It is quite similar to the better-known Pleurotus ostreatus, and like that species is cultivated and sold in markets in Europe and China, but it is distinguished because its gills are very decurrent, forming a network on the stem.
Isolichenan, also known as isolichenin, is a cold-water-soluble α-glucan occurring in certain species of lichens. This lichen product was first isolated as a component of an extract of Iceland moss in 1813, along with lichenin. After further analysis and characterization of the individual components of the extract, isolichenan was named in 1881. It is the first α-glucan to be described from lichens. The presence of isolichenan in the cell walls is a defining characteristic in several genera of the lichen family Parmeliaceae. Although most prevalent in that family, it has also been isolated from members of the families Ramalinaceae, Stereocaulaceae, Roccellaceae, and Cladoniaceae. Experimental studies have shown that isolichenan is produced only when the two lichen components – fungus and alga – are growing together, not when grown separately. The biological function of isolichenan in the lichen thallus is unknown.
Hypsizygus ulmarius, also known as the elm oyster mushroom, and less commonly as the elm leech, elm Pleurotus, is an edible fungus. It has often been confused with oyster mushrooms in the Pleurotus genus but can be differentiated easily as the gills are either not decurrent or not deeply decurrent. While not quite as common as true oyster mushrooms, they have a wide range globally in temperate forests. The mushrooms and vegetative hyphae of this species have been studied in recent years for their potential benefits to human health, and mycoremediation.
Pleurotus opuntiae is a species of Agaricales fungus that grows in the semi-arid climate of central Mexico and in New Zealand, whose mushroom is edible and considered a delicacy in the cuisine of indigenous peoples of Mexico. It is known as hongo de maguey común in Mexican Spanish, seta de chumbera/nopal in Peninsular Spanish, and kjoo'wada in Otomi language. Phylogenetic research has shown that while it belongs to P. djamor-cornucopiae clade, it forms its own intersterility group, but it has also been claimed to be genetically inter-incompatible with P. australis, P. ostreatus (extra-limital), P. pulmonarius and P. purpureo-olivaceus of New Zealand.
Mushrooms have been cultivated with novel psychedelic substancess through biotransformation, by artificially adding selected psychoactive substances to the growing substrate. The biotransformed alkaloids could be found in the culture medium.
Pleurotus euosmus, also known as tarragon oyster mushroom, is a species of edible fungus in the genus Pleurotus, It is quite similar to the better-known Pleurotus ostreatus, but it is distinguished by its strong smell reminiscent of tarragon and substantially larger spores.
... the grey oyster mushroom (Pleurotus ostreatus) cannot be imported into New Zealand because it could pose a risk to our forest industry.
