Armillaria mellea is widely distributed in temperate regions of the Northern Hemisphere. The fruit body or mushroom, commonly known as stump mushroom, stumpie, honey mushroom, pipinky or pinky, grows typically on hardwoods but may be found around and on other living and dead wood or in open areas.Armillaria, honey fungus, survey. The problem. For many years it was thought that Armillaria existed as just one very variable species. However, the range of species has now been confirmed and there are seven species recorded in the UK. These are A. mellea, A. gallica, A. ostoyae, A. cepistipes, A. borealis, A. tabescens and A. ectypa.Armillaria Root Disease Armillaria ostoyae Key Wildlife Value: Armillaria ostoyae creates short-term snags of any size and all sizes of down wood, by killing and decaying the root system and butts of host trees. Canopy gaps resulting from armillaria root disease expand slowly, resulting in a more diverse stand structure and at times a more diverse plant species composition, as resistant or non.

Detrimentally, rusts, smuts, and molds cost billions of dollars through crop disease and spoilage while forest pathogens such as the honey mushroom ( Armillaria ostoyae ) and root-butt rot ( Heterobasidion annosum ) similarly threaten the timber industry. Some are toxic when eaten, such as the infamous destroying angel ( Amanita phalloides.

Armillaria mellea: a destructive pathogen of trees. The genus Armillaria contains about 40 species of important wood-rot fungi which are widely distributed across the world. Their basic behaviour is similar, because all the species invade the roots and cause a progressive white rot (see later).

Notes: Identification of Armillaria to species is very difficult in the field. Infection of living hosts narrows the number of species that one might be dealing with. DNA testing to identify a number of the pathogenic species is possible (see Submit tab on Home page for DNA testing laboratory for Armillaria genus or several Armillaria species).

Armillaria ostoyae is recognized by the presence of large, dark brown scales present up to maturity on a reddish brown pileus, a thin, membranous white ring with blackish marginal scales. The stipe, initially white, is cylindrical, slightly bulbous at the base and, in younger specimens, with brown transverse scales just below the ring. The basidia have a basal clampconnexion, but the hyphae.

The name Armillaria ostoyae has been applied for nearly 40 years to the Armillaria species that causes a major root-rot of conifers throughout Europe, the northern United States, much of Canada, and more recently in China.However, C.H. Peck described this species in 1900 under the name A. solidipes, well before the name A. ostoyae was coined by Romagnesi in 1970.

The fungus Armillaria mellea (also known as Armillariella mellea or Armillariella elegans) is one of the most common root-rotting fungi, but seems to exist in several forms, some of which have now been formally described as separate species (e.g. Armillaria mellea, A, gallica, A. ostoyea and A. tabescens).

Throughout its circumboreal distribution, Armillaria ostoyae (Romagnesi) Herink is a principal cause of Armillaria root rot disease (Guillaumin et al. 1989, Morrison and Pellow 2002). In western North America, it adversely impacts commercial timber production by causing significant tree mortality and a reduction in tree growth (Williams et al.

The various Armillaria species found in deciduous forests act primarily as secondary pathogens of stressed trees. Armillaria ostoyae, the predominant Armillaria species in coniferous forests, is pathogenic with the degree of pathogenicity being determined by the inoculum potential of the fungus. Inoculum potential is the energy available to the.

Honey fungus rhizomorphs can spread up to 9m (30ft) away from the original infected plant. One species of honey fungus (Armillaria ostoyae) in America is believed to be the largest living organism on earth. It grows in the Malheur National Forest in east Oregon and is 3.5 miles across.
