Blue Chanterelle Look-Alikes
Polyozellus multiplex is easy to distinguish among other types of mushrooms. Its dark-colored clusters and wavy caps are recognizable, even to the layman. However, there is a species of mushroom that is very similar to the Polyozellus multiplex. This look-alike is Craterellus cornucopioides, colloquially known as the horn-of-plenty mushroom. It is also known as the black chanterelle or black trumpet. This particular species is of the Cantharellaceae family and is also edibleⁱⁱⁱ. C.cornucopioides has a black fruit body and grows in North America, Europe, and East Asia under beech or oak trees and mossy areas. The only apparent distinction from Polyozellus multiplex is the thin flesh and trumpet-like shape.
Moreover, another species often mistaken for Polyozellus multiplex by non-experts is Gomphus clavatus, commonly known as pig’s ears or the violet chanterelle of the Gomphaceae family. This edible fungus species has wavy edges similar to P. multiplex and can occur in clusters or fairy ringsⁱⱽ. It has a vase-shaped body and is brownish to lilac in color. The feeding technique of both species is also similar. The same applies to their habitat: both P. multiplex and G.clavatus enjoy coniferous forests. The confusion stems from the outer appearance of the fruit body which is wavy in both species. Otherwise, the two species are quite distinct.
Blue Chanterelle Benefits
The first notable benefit of the Blue Chanterelle is culinary so much so that it is very popular in East Asian cuisine. This popularity has also reached the shores of North America where they are also hunted and consumed. It is best consumed cooked. The culinary use of these mushrooms extends to a panoply of dishes. It can also be preserved by drying the fruit bodies and keeping them in a dry and cool environment.
What is more important is the health benefits of Polyozellus multiplex. This species of mushroom secretes polyozellin which is a chemical used in the treatment of Alzheimer’s disease. This chemical substance inhibits the work of the enzyme prolyl endopeptidase (PEP) which processes the amyloid precursor protein for the onset of Alzheimer’s diseaseⱽ. This ability has rendered this mushroom popular in the pharmaceutical community due to its immense benefits for drug production.
Furthermore, Polyozellus multiplex exhibits antitumor properties. As a matter of fact, ingesting the mushroom may have benefits that help fight stomach cancer as it acts as a suppressor and powerful chemopreventive agentⱽⁱ. The mushroom has enzymes that have potential to protect the body against cancer. These enzymes include glutathione S-transferase and superoxide dismutase. Polyozellus multiplex also increases the concentration of glutathione, a substance that is an antioxidant that prevents cellular damage. Moreover, consuming this mushroom may increase the protein production of p53, also known as the Guardian of the Genome, an important tumor antigen that may help prevent cancer.
Blue Chanterelle Dosage
Although Blue Chanterelle has numerous health benefits, it is not widely known or used as a medicinal plant. However, only a low concentration of around 0.5% to 1% is sufficient to kick-start the production of useful enzymes in the body.
Blue Chanterelle Toxicity, Safety & Side Effects
The Polyozellus multiplex mushroom is not poisonous or toxic at all. It is considered safe for consumption and thought to have little to no side effects or interaction with drugs.
