Suillus
''Suillus'' is a genus of basidiomycete fungi in the family Suillaceae and order Boletales. Species in the genus are associated with trees in the pine family (Pinaceae), and are mostly distributed in temperate locations in the Northern Hemisphere, although some species have been introduced to the Southern Hemisphere. Taxonomy The genus ''Suillus'' was first defined by Pier Antonio Micheli in his 1729 work ''Nova plantarum genera'', however it is not valid as it predates the 1753 start of Linnean taxonomy. Fries sanctioned the use by British botanist Samuel Frederick Gray in the first volume of his 1821 work ''A Natural Arrangement of British Plants''. Setting ''Suillus luteus'' as the type species, he described the genus as those mushrooms with a centrally placed stipe, a distinct ring, a circular cap, and tubes that are stuck together. They have been commonly called "slippery jacks" because the cap of the fruit body is sometimes slimy. The genus name is derived from the Lat ...

Siberian Pine
''Pinus sibirica'', or Siberian pine, in the family Pinaceae is a species of pine tree that occurs in Siberia from 58°E in the Ural Mountains east to 126°E in the Stanovoy Range in southern Sakha Republic, and from Igarka at 68°N in the lower Yenisei valley, south to 45°N in central Mongolia. Description ''Pinus sibirica'' is a member of the white pine group, ''Pinus'' subgenus ''Strobus'', and like all members of that group, the leaves ('needles') are in fascicles (bundles) of five, with a deciduous sheath. They are 5–10 cm long. Siberian pine cones are 5–9 cm long. The 9–12 mm long seeds have only a vestigial wing and are dispersed by spotted nutcrackers. Siberian pine is treated as a variety or subspecies of the very similar Swiss pine (''Pinus cembra'') by some botanists. It differs in having slightly larger cones, and needles with three resin canals instead of two in Swiss pine. Like other European and Asian white pines, Siberian pine is very ...

Russian Far East
The Russian Far East (russian: Дальний Восток России, r=Dal'niy Vostok Rossii, p=ˈdalʲnʲɪj vɐˈstok rɐˈsʲiɪ) is a region in Northeast Asia. It is the easternmost part of Russia and the Asian continent; and is administered as part of the Far Eastern Federal District, which is located between Lake Baikal in eastern Siberia and the Pacific Ocean. The area's largest city is Khabarovsk, followed by Vladivostok. The region shares land borders with the countries of Mongolia, China, and North Korea to its south, as well as maritime boundaries with Japan to its southeast, and with the United States along the Bering Strait to its northeast. The Russian Far East is often considered as a part of Siberia (previously during the Soviet era when it was called the Soviet Far East). Terminology In Russia, the region is usually referred to as just "Far East" (). What is known in English as the Far East is usually referred to as "the Asia-Pacific Region" (, abb ...

Boletales
The Boletales are an order of Agaricomycetes containing over 1300 species with a diverse array of fruiting body types. The boletes are the best known members of this group, and until recently, the Boletales were thought to only contain boletes. The Boletales are now known to contain distinct groups of agarics, puffballs, and other fruiting-body types. Taxonomy The order Boletales originally was created to describe boletes, but based on micromorphological and molecular phylogenetic characteristics, a large number of nonbolete species have recently been reclassified to belong to this group, as well. The order also includes some gilled mushrooms, in the families Gomphidiaceae, Serpulaceae, Tapinellaceae, Hygrophoropsidaceae, and Paxillaceae, which often have the same flesh texture as the boletes, spore-bearing tissue which is also easily separable from the cap, and similar microscopic characteristics of spores and cystidia.

Symbiosis
Symbiosis (from Greek , , "living together", from , , "together", and , bíōsis, "living") is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic. The organisms, each termed a symbiont, must be of different species. In 1879, Heinrich Anton de Bary defined it as "the living together of unlike organisms". The term was subject to a century-long debate about whether it should specifically denote mutualism, as in lichens. Biologists have now abandoned that restriction. Symbiosis can be obligatory, which means that one or more of the symbionts depend on each other for survival, or facultative (optional), when they can generally live independently. Symbiosis is also classified by physical attachment. When symbionts form a single body it is called conjunctive symbiosis, while all other arrangements are called disjunctive symbiosis."symbiosis."

Mycorrhiza
A mycorrhiza (from Greek μύκης ', "fungus", and ῥίζα ', "root"; pl. mycorrhizae, mycorrhiza or mycorrhizas) is a symbiotic association between a fungus and a plant. The term mycorrhiza refers to the role of the fungus in the plant's rhizosphere, its root system. Mycorrhizae play important roles in plant nutrition, soil biology, and soil chemistry. In a mycorrhizal association, the fungus colonizes the host plant's root tissues, either intracellularly as in arbuscular mycorrhizal fungi (AMF or AM), or extracellularly as in ectomycorrhizal fungi. The association is sometimes mutualistic. In particular species or in particular circumstances, mycorrhizae may have a parasitic association with host plants. Definition A mycorrhiza is a symbiotic association between a green plant and a fungus. The plant makes organic molecules such as sugars by photosynthesis and supplies them to the fungus, and the fungus supplies to the plant water and mineral nutrients, s ...
