The world's most validated mushroom. Extensive studies! Pre-clinical trial confirmed for local extract;
Reishi is the common name for two closely related polypores: Ganoderma sichuanense (= G. lingzhi, the Asian lingzhi of traditional use) and G. lucidum, which also occurs wild in South Africa. It is an ancient, highly revered species in functional mycology. Known as the 'Mushroom of Immortality' or 'Panacea polypore', it features a deep history of therapeutic classification. The organism produces an abundance of complex structural macromolecules that support vital biological systems, rendering it a premier target species for both wild identification and intensive organic substrate cultivation.
Identification & Ecology| Habitat | Saprotrophic and weakly parasitic on dead, decaying, or dying hardwood tree stumps, roots, and logs. Found on oaks (introduced in SA) and other broadleaf trees. |
| Season | Perennial tough woody brackets found year-round in natural wild settings; dynamic growth flushes occur during warm summer periods. |
| ID Features | Distinctive laccate (shiny, heavily varnished) upper crust transitioning from deep red-maroon to a warm yellowish-white edge. Possesses a white to cream-colored fine porous underside instead of gills, dropping a rich, dense rust-brown spore cloud upon full maturity. Can develop into flat shelf brackets (conks) or multi-branched stalks depending on natural airflow conditions. |
| Triterpenoids | Over 150 lanostane triterpenoids identified, including ganoderic acids. |
| Beta-glucans | High-molecular-weight fungal polysaccharides embedded natively inside the dense, woody chitin cell wall layers. |
| Sterols & Ergosterol | Essential fungal plasma membrane components that act as natural precursor molecules to essential Vitamin D2. |
| Adenosine | Naturally occurring nucleoside compound found balanced within the dense internal structural mycelium fibers. |
Wild specimens develop incredibly tough, corky, and woody flesh making them completely unpalatable as a culinary food. Instead, the harvested brackets are collected, dried, and prepared as long-steeped traditional hot water decoctions or ethanol (drinking-grade alcohol) tinctures, often combined as a dual extract to access the locked cellular components. Mushroom Guru's MG-LZ8™ is a dual-phase extract of antler-form G. sichuanense - see the MG-LZ8™ page.
CautionsRare reports of liver injury, including with reishi powder. May interact with blood thinners, blood-pressure and diabetes medicines. Stop 2 weeks before surgery. Avoid in pregnancy. Ask your doctor first if you take immune-suppressing medication.
PSK (Krestin) — approved cancer adjuvant drug in Japan since 1977. One of the most studied medicinal mushrooms.…
PSK (Krestin) — the polysaccharide fraction of Turkey Tail — has been an approved cancer adjuvant drug in Japan since 1977. One of the most clinically studied medicinal mushrooms. PSP, a related fraction developed in China, has also been studied for immune support alongside conventional treatment.
Identification & Ecology| Habitat | Saprotrophic — on dead hardwood stumps and logs; SA parks and forests nationwide |
| Season | Year-round; abundant after rain |
| ID Features | Thin flexible brackets with concentric colour zones (blue, brown, cream, tan); velvety upper surface; white fine pores underneath; no stipe; grows in overlapping clusters |

| PSP | Second protein-bound polysaccharide — NK cell and T-cell activation, immune restoration post-chemotherapy |
| Beta-glucans | Dectin-1 and TLR2 pathway activation — macrophage and NK cell priming |
| Phenolic antioxidants | Free radical scavenging — antioxidant activity |
One of the most common medicinal mushrooms in SA, on dead hardwood stumps across the country. The concentric colour-banded surface, thin flexible bracket, and fine white pores confirm identity. Not to be confused with Stereum hirsutum (False Turkey Tail) — which has a smooth pore-less underside.
CautionsSpeak to your oncologist before combining with chemotherapy. Caution with immune-suppressing medication. Side effects reported include nausea and darkened stools or nails.
NGF stimulation in cell and animal studies. Small trials in mild cognitive impairment.…
Lion's Mane contains two families of compounds - hericenones (fruiting body) and erinacines (mycelium) - that stimulate Nerve Growth Factor (NGF) synthesis in cell and animal studies. Erinacine A has been shown to reach the brain in rats; human data are limited. Small clinical trials suggest possible benefit in mild cognitive impairment, but the evidence is still limited.
Identification & Ecology| Habitat | On dead and dying hardwood — oak, beech, walnut; increasingly cultivated SA |
| Season | Autumn to winter; year-round in cultivation |
| ID Features | Cascading white spines (1–5cm long) in a globose cluster; no cap or stipe; pure white to cream when fresh; yellowing with age; distinctive cascade of icicle-like spines |
| Hericenones | Fruiting body compounds — stimulate NGF synthesis in cell studies |
| Erinacines | Mycelium compounds — stimulate NGF in animal studies; erinacine A reaches the brain in rats |
| NGF/BDNF stimulation | Studied for cognitive function and peripheral nerve repair (mostly animal data) |
| Anti-neuroinflammatory | NF-κB inhibition in microglia — neuroinflammation reduction |
| Gut-brain axis | Modulates enteric nervous system — anxiety, depression, gut motility |
No dangerous lookalikes — the cascading white spines are unique. Cultivated on hardwood sawdust or supplemented blocks. Best consumed as concentrated extract — raw powder has limited bioavailability. Both fruiting-body and mycelium extracts have been used in trials.
CautionsAllergic reactions (skin and breathing) have been reported. May affect blood clotting and blood sugar - caution with blood thinners and diabetes medicines.
Flat perennial bracket — white underside bruises brown permanently. Related bioactives to Reishi.…
A close relative of Reishi sharing the same family of ganoderic acid triterpenoids and immunomodulatory polysaccharides, though less studied. The permanently brown-bruising white underside is the primary identification feature — and the source of its common name (used by artists to draw on). Used in traditional medicine in Asia and Europe.
Identification & Ecology| Habitat | Parasitic and saprotrophic on hardwood trees — widespread in SA |
| Season | Perennial — adds a new growth layer annually; may persist for decades |
| ID Features | Flat shelf bracket; grey-brown upper surface with concentric rings; bright white underside bruises dark brown permanently when scratched (used for artwork); cocoa-brown spore cloud; hard, woody |
| Ganoderic Acids | Lanostane triterpenoids — anti-inflammatory, hepatoprotective |
| Beta-glucans | Immunomodulatory polysaccharides |
| Adenosine | Anti-platelet aggregation; cardiovascular support |
The white underside that permanently bruises brown is the definitive field mark. Draw on it with a pointed stick and the image remains. Very hard and woody — requires hot water or alcohol extraction for bioavailability. More abundant in SA than Reishi.
CautionsNo human safety data. Do not combine with germanium supplements, which have caused kidney failure.
Natural lovastatin in some strains (variable). Beta-glucan pleuran — studied for immune activity.…
Beyond its culinary value, some Oyster mushroom strains contain lovastatin - the same molecule as the statin drug - though amounts vary widely and are usually far below drug doses. Also contains pleuran, a beta-glucan studied for immune activity in small clinical trials.
Identification & Ecology| Habitat | Saprotrophic — on dead hardwood stumps and logs; cultivated on straw |
| Season | Year-round in cultivation; autumn to winter wild |
| ID Features | Fan or oyster-shaped brackets; grey to grey-brown; white gills running down the short stipe; white to lilac-grey spore print; mild smell |
| Lovastatin | Natural statin — inhibits HMG-CoA reductase; cholesterol reduction |
| Pleuran | Beta-1,3/1,6-glucan — clinical trials confirm immune enhancement; NK cell activation |
| Ergosterol | Vitamin D2 precursor — UV activation |
| Lovastatin (mevinolin) | Same molecule as the drug; amounts vary by strain and are far below drug doses - not a substitute for prescribed statins |
The most accessible medicinal-edible dual-purpose mushroom. Grey fan-shaped brackets with gills running down a short off-centre stem are consistent with oyster mushroom - but confirm wild specimens with an experienced identifier: toxic lookalikes on wood include Omphalotus (Jack-o'-lantern, Ghost Fungus) and Pleurocybella (Angel Wings). Cultivated on straw using the Cold Lime Soak method — see our free Level 2 training course.
CautionsNot a substitute for prescribed statins. Growers can develop a spore allergy - ventilate fruiting rooms.
Lentinan — approved injectable cancer adjuvant in Japan since 1985.…
Shiitake contains Lentinan — a specific beta-1,3-D-glucan that has been an approved injectable drug in Japan since 1985, given alongside chemotherapy for gastric cancer (this is not equivalent to eating shiitake). It also contains eritadenine, which reduces blood cholesterol, and multiple other bioactive compounds.
Identification & Ecology| Habitat | Saprotrophic on dead hardwood logs (oak, beech, poplar); cultivated on supplemented hardwood |
| Season | Year-round in cultivation; spring and autumn on logs |
