Ectomycorrhizal symbiosis, showing root tips with fungal mycelium from the genus Amanita. An ectomycorrhiza (from Greek ἐκτός ektos, "outside", μύκης mykes, "fungus", and ῥίζα rhiza, "root"; pl. ectomycorrhizas or ectomycorrhizae, abbreviated EcM) is a form of symbiotic relationship that occurs between a fungal symbiont, or mycobiont, and the roots of various plant species.
Mycorrhizal network. Nutrient exchanges and communication between a mycorrhizal fungus and plants. White threads of fungal mycelium are sometimes visible underneath leaf litter in a forest floor. A mycorrhizal network (also known as a common mycorrhizal network or CMN) is an underground network found in forests and other plant communities ...
A mycorrhiza is a symbiotic association between a green plant and a fungus. The plant makes organic molecules by photosynthesis and supplies them to the fungus in the form of sugars or lipids, while the fungus supplies the plant with water and mineral nutrients, such as phosphorus, taken from the soil. Mycorrhizas are located in the roots of ...
Ectomycorrhizal fungi increase primary production in host plants, with multi trophic effects. In this way, extramatrical mycelium is important to the maintenance of soil food webs , [6] supplying a significant nutritive source to invertebrates and microorganisms as well as overall plant competition and diversity.
Lactarius is a genus of mushroom -producing, ectomycorrhizal fungi, containing several edible species. The species of the genus, commonly known as milk-caps, are characterized by the milky fluid ("latex") they exude when cut or damaged. Like the closely related genus Russula, their flesh has a distinctive brittle consistency.
The mechanism presented is that ectomycorrhizal fungi can compete with free-living decomposers for nutrients, and thereby limit the rate of total decomposition. Since then there have been several other reports of ectomycorrhizal fungi reducing activity and decomposition rates of free-living decomposers and thereby increasing soil carbon storage.
The ericoid mycorrhiza is a mutualistic relationship formed between members of the plant family Ericaceae and several lineages of mycorrhizal fungi. This symbiosis represents an important adaptation to acidic and nutrient poor soils that species in the Ericaceae typically inhabit, [1] including boreal forests, bogs, and heathlands.
Laccaria bicolor. Laccaria bicolor is a small tan-colored mushroom with lilac gills. It is edible but not choice, [ 2] and grows in mixed birch and pine woods. It is found in the temperate zones of the globe, in late summer and autumn. [ 3] L. bicolor is an ectomycorrhizal fungus used as a soil inoculant in agriculture and horticulture .
