CLINICAL SUMMARY Although all Armillaria species were for many years generally considered edible when thoroughly cooked, some members of the honey fungus group (including Armillaria mellea, the type species of this genus) that occur on hardwoods are considered by some to be suspect, as cases of poisoning have been linked to eating these fungi; this is most probably due to a small but significant proportion of people being … As well as being essential for the growth of G. elata, it has been shown that Armillaria species are involved in sclerotium formation in Polyporus umbellatus (see P. umbellatus section). The cultivation, bioactive components and pharmacological effects of Armillaria mellea. Analysis of indole compounds in Armillaria mellea fruiting bodies. This state of affairs was too easy for mycologists, however. Early reports indicated that A. mellea and G. elata shared the same active components but it is now known that they differ in their active metabolites. In most areas of North America, Armillaria solidipes can be separated from other species of Armillaria on the basis of its brown colors, the fairly prominent scales featured on its cap, and the well developed ring on its stem. Kuo 09200101, 09230608, 05210701, 09271501. Armillaria mellea . Armillaria mellea. One must consider that multiple trees on a site are infected and may have decayed roots when the fungus is confirmed on an individual tree. 1990;56(2):198–201. However, these latent infections (the number of which increases with time) can resume their evolution and colonize the root system if the tree is weakened by age or environment ( Delatour and Guillaumin, 1995 ). 16. But Armillaria mellea is in a position to take advantage should a change occur! A polysaccharide from Armillaria mellea exhibits strong in vitro anticancer activity via apoptosis-involved mechanisms.

Armillaria mellea, commonly known as honey fungus, is a basidiomycete fungus in the genus Armillaria. Armillaria spp. A fungicide is labeled for Armillaria (Reliant® (active ingredient phosphoric acid) but efficacy is unknown. These fungi were previously thought to be one species, known as Armillaria mellea, however, research has shown that there are actually a number of species within the Armillaria group. The classic "honey mushroom," Armillaria mellea, was first named from Europe in the 18th Century; here in North America it turns out to be limited to roughly the eastern half of North America, from about the Great Lakes to the Gulf Coast and the East Coast—although it has also been reported from northern California. Although responsible for the death of many trees and garden shrubs, A. mellea is essential for the growth of other plants, including the important Chinese herb Gastrodia elata (Tian Ma), which is used to treat conditions including vertigo, dizziness, headache, stroke and convulsions and whose medical properties A. mellea mirrors. As parasites, the fungi cause mortality, wood decay, and growth reduction. 7. 11. 2011;68(1):93–97. Dose – Mycelial tablets are used in China 3-4g/day. Donnelly DM, Abe F, Coveney D, Fukuda N, O’Reilly J, Polonsky J, Prangé T. J Nat Prod. For many years it was thought that Armillaria existed as just one very variable species. J New Med. The fungus remains alive and constitutes a 'latent infection' limited in area and showing no evolution. Armillaria mellea (Vahl:Fr.) Armillaria is a genus of fungi that includes the A. mellea species known as honey fungi that live on trees and woody shrubs. Watanabe N, Obuchi T, Tamai M, Araki H, Omura S, Yang JS, Yu DQ, Liang XT, Huan JH. 2012;51(4):663–667.

Ferguson BA, Dreisbach TA, Parks CG, Filip GM, Schmitt CL. 15. Although this name was widely used for nearly all members of the genus until the 1970's, true Armillaria mellea has a smaller distribution, occurring mainly in the southeastern United States up into the northeast into Québec and in the midwest in the hardwood forests, although it is occasionally found on conifers in mixed forests. 9. Armillaria grow from a single fertilized white spore and spread vegetatively through hyphae, threadlike filaments of cells that aggregate to form long, cordlike bundles called rhizomorphs. Someone had to go and point out that Armillaria contained many mushrooms that differed widely in their physical features. Almond Mushroom (Royal / Sun Agaric) – Agaricus subrufescens, Cordyceps – Ophiocordyceps sinensis / Cordyceps militaris, Wood Ear – Auricularia auricula-judae / Auricularia polytricha. The fungus thus acquires energy (inoculum potential), enabling it to infect healthy trees adjacent to the colonized stumps. This species is also found in many other parts of the world including North America. Zhou Linshen. Thus, using the "biological species concept" (the concept we often use, for example, to define species of large animals: if they can't mate they belong to separate species), these mycologists defined about nine or ten species of Armillaria in North America. Most of the honey mushrooms, for example, were parasitic wood rotters (often pathogenic and killing the tree), while other species of Armillaria were mycorrhizal. Armillaria mellea, commonly known as honey fungus, is a basidiomycete fungus in the genus Armillaria. The wide host range of A. mellea is problematic as virtually any hardwood tree can be infected along with a wide array of shrub species. . 1950), including shrubs, fruit trees […] Armillaria mellea. In addition, nucleoside analogues play a role in some of A. mellea’s functions and a number of indole compounds have been isolated including tryptamine, L- tryptophan and serotonin, with A. mellea fruiting bodies containing 2.207mg serotonin per 100g dry weight6,7.

It is a plant pathogen and part of a cryptic species complex of closely related and morphologically similar species. REFERENCES: (Vahl, 1790) Kummer, 1871. Armillaria ostoyae. Moribund stumps or roots provide a food source from which the fungus can spread to infected coffee. For a while mycologists played around with the idea of putting the honey mushrooms into a separate genus called "Armillariella," but eventually it became clear that most of the 250 or so species of Armillaria (not just the "honeys") needed to be distributed among other genera.

Fortunately, physical features do separate some of the species, and the fairly well documented geographical ranges of the mushrooms help to separate others (though some pairs of species, like Armillaria gallica and Armillaria calvescens, remain basically inseparable if the mushrooms are found in certain geographical areas). Several antibiotics, primarily sesquiterpene aryl esters, have been isolated from A. mellea and show strong action against gram-positive bacteria (Staphylococcus, Streptococcus, Enterococcus etc. by Michael Kuo. Common names Honiggelber Hallimasch in German echte honingzwam in Dutch Ægte honningsvamp in Danish Echte honingzwam in Dutch sydlig honungsskivling in Swedish Bibliographic References. More importantly, mycologists pointed out that the mushrooms in question differed in their fundamental ecological roles. Ecology: Pathogenic and parasitic on the wood of hardwoods (and occasionally on conifers); causing a white, pulpy rot in the wood; spreading through wood, and from tree to tree, by means of long black rhizomorphs; typically appearing in large clusters on wood in the fall after rains, but found nearly year-round in warmer climates; distributed in eastern and southeastern North America, and in California. 10.
