Reishi mushrooms are packed with powerful medicinal compounds
Reishi mushrooms, also known as Ganoderma lucidum, have been used in Eastern medicine for hundreds of years, particularly in Asian countries. They are often referred to by their common names: lingzhi, varnish shelf, or artists conk. These mushrooms contain polysaccharides, peptides, and triterpenoids, which are believed to be responsible for their potential health benefits. They are also a source of dietary fibre, minerals, vitamins, and amino acids.
Reishi mushrooms are known for their purported medicinal properties, especially their ability to boost the immune system and potentially help fight cancer. Laboratory test-tube studies have shown that these mushrooms may be effective in cancer treatment and shrinking tumours. Additionally, there is some evidence from in vitro and animal studies that suggest reishi mushrooms support the immune system. However, it is important to note that human studies on the effects of this fungus are limited, and more research is needed to confirm these benefits conclusively.
One of the key medicinal compounds found in reishi mushrooms is beta-glucan, a type of polysaccharide. Beta-glucan has been shown to have immunomodulatory effects, meaning it can help regulate and enhance the body's immune response. This makes reishi mushrooms a potential adjunct to standard cancer treatments, as they can help reduce the side effects of chemotherapy by boosting the immune system.
Reishi mushrooms are also a source of ganoderic acids, which are triterpenoids unique to this type of mushroom. These compounds have been studied for their potential anti-inflammatory, antioxidant, and anticancer properties. Additionally, ganoderic acids have been found to have hypolipidemic effects, which can help lower cholesterol levels and improve heart health.
While reishi mushrooms have been traditionally used for medicinal purposes, it is important to be aware of potential side effects and interactions. Reishi mushrooms may increase the risk of bleeding, especially in individuals taking anticoagulant or antiplatelet medications. They can also interact with high blood pressure medications and may lower blood pressure. Pregnant or breastfeeding women should avoid consuming reishi mushrooms, as there is limited research on their safety in these circumstances. Furthermore, long-term consumption of powdered reishi mushrooms has been associated with potential liver toxicity. Consulting a healthcare professional before incorporating reishi mushrooms into your diet or treatment plan is highly recommended.

Ganoderma curtisii is a species of mushroom commonly known as Curtis' Ganoderma
Ganoderma curtisii, commonly known as Curtis' Ganoderma, is a species of mushroom. It was first identified in 1849 by Miles Berkeley, who named it Polyporus curtisii. In 1908, William Alphonso Murrill transferred it to the genus Ganoderma. Ganoderma curtisii is a wood-decaying polypore found in eastern North America, particularly in the southeastern region of the United States.
This species of mushroom is characterised by its shelf-like growth habit and reddish-brown or white cap with a smooth or slightly cracked surface. It is genetically distinct from G. lucidum, which is commonly known as the reishi or lingzhi mushroom in China and Japan, respectively. Ganoderma curtisii lacks the characteristic glossy or varnished appearance of G. lucidum and is generally smaller in size.
The flesh of Ganoderma curtisii is spongy in pore tissue and firm in the stipe. Its pores bruise brown when damaged, similar to other Ganoderma species. The habitat of this mushroom is decaying stumps and roots of hardwoods, which aligns with the habitat of G. lucidum (G. sessile). However, the overlap in habitat has led to debates about the distinctness of Ganoderma curtisii as a species.
Some mycologists consider Ganoderma curtisii to be a separate species from G. lucidum, while others, such as Volk, Gilbertson, and Ryvarden, authors of "North American Polypores," do not. Recent molecular studies have supported the idea that G. lucidum sensu stricto is absent from North America and that the mushroom widely referred to as G. lucidum in North America is actually G. sessile, a member of the Ganoderma resinaceum complex, further reinforcing the distinctness of Ganoderma curtisii.

Reishi mushrooms are not gilled mushrooms, their underside looks like a small sponge with dots
Reishi mushrooms, also known as the "mushroom of immortality", are a type of fungus that has been celebrated for its medicinal properties for thousands of years. The scientific name for Reishi mushrooms is Ganoderma, and there are many different species within this genus found all over the world.
Ganoderma mushrooms are polypores, meaning they have a bright white pore surface on their underside that bruises brown when touched or scratched. Unlike gilled mushrooms, Ganoderma mushrooms do not produce spore prints easily. Instead, their spores are usually found coating the tops of the caps at full maturity. The underside of the fruiting body has a distinct bitter taste, which is characteristic of Reishi mushrooms.
The Ganoderma sessile, in particular, is a softer variety of Reishi mushroom that often grows very close to the ground in lawns. It can be easily cut with a knife or trimmed with scissors. This species is native to the United States and is known to have medicinal properties.
Reishi mushrooms have a bright and unique appearance, with a shiny red body and a white underside covered in tiny spore-releasing pores. They are known to grow on dead and dying trees and can be cultivated both indoors and outdoors. The Japanese were the first to cultivate Reishi mushrooms in 1970, making them more accessible to the general public.
In summary, Reishi mushrooms, including the Ganoderma sessile, are not gilled mushrooms. Their underside, or pore surface, has a distinct white colour and a bitter taste, resembling a small sponge with dots or pores.

Ganoderma mushrooms can be pulled off their substrate and trimmed with scissors
Ganoderma is a genus of more than 300 species of wood-decaying fungi, commonly known as reishi, lingzhi, varnish shelf, or artist's conk. They are widely distributed shelflike or knoblike fungi that feed either as saprotrophs on dead wood or as parasites on the live wood of hardwood trees, conifers, or palms.
Ganoderma sessile, also known as reishi, is a softer variety of Ganoderma mushroom that often grows very close to the ground in lawns. It can be cut with a knife where it attaches to its tree host or just above the ground. However, it often contains a lot of debris, such as leaf litter, grass, and dirt, so care must be taken to ensure that none of these inclusions are harmful plants, such as poison ivy, which can sometimes grow through the mushroom.
Another method of harvesting Ganoderma mushrooms, including G. sessile, is to pull them off their substrate and trim them with a sharp pair of scissors. This method is often used by mushroom farmers who want to avoid leaving large chunks of substrate attached to the mushrooms. While twisting and pulling can be effective, it can also leave divets that may provide an opportunity for molds to establish. Using scissors to trim the mushrooms can help to reduce the amount of substrate left attached, potentially reducing the risk of contamination.
It is important to note that G. sessile should be carefully inspected for mold, as it can harbor harmful molds, especially if it is past its prime. The pore surface should be bright white at harvest, and specimens with a darkened or moldy pore surface should be avoided. Proper storage is also crucial, as reishi mushrooms will stay fresh for 3-5 days under refrigeration and are typically stored in paper bags to prevent spoilage.
In summary, Ganoderma mushrooms, including G. sessile, can be pulled off their substrate and trimmed with scissors. This method may offer advantages over simply twisting and pulling the mushrooms, as it can help to reduce the risk of contamination by leaving less substrate attached. However, care must be taken to ensure proper handling and storage to avoid mold and spoilage.
