Answer the following question: Information: - Leccinum is a genus of fungi in the family Boletaceae. It was the name given first to a series of fungi within the genus "Boletus", then erected as a new genus last century. Their main distinguishing feature is the small, rigid projections (scabers) that give a rough texture to their stalks. The genus name was coined from the Italian "Leccino", for a type of rough-stemmed bolete. The genus has a widespread distribution, especially in north temperate regions, and contains about 75 species. - Phylloporus is a genus of fungi in the family Boletaceae (suborder Boletineae). The genus has a cosmopolitan distribution, and contains about 50 species, mostly in tropical areas. - Tylopilus felleus, commonly known as the bitter bolete or the bitter tylopilus, is a fungus of the bolete family. Its distribution includes east Asia, Europe, and eastern North America, extending south into Mexico and Central America. A mycorrhizal species, it grows in deciduous and coniferous woodland, often fruiting under beech and oak. Its fruit bodies have convex to flat caps that are some shade of brown, buff, or tan, and typically measure up to in diameter. The pore surface is initially white before turning pinkish with age. Like most boletes it lacks a ring, and it may be distinguished from "Boletus edulis" and other similar species by its unusual pink pores and the prominent dark brown netlike pattern on its stalk. - Leccinum scabrum, commonly known as the rough-stemmed bolete, scaber stalk, and birch bolete, is an edible mushroom in the family Boletaceae, and was formerly classified as "Boletus scaber". The birch bolete is widespread in Europe, in the Himalayas in Asia, and elsewhere in the Northern Hemisphere, occurring only in mycorrhizal association with birch trees. It fruits from June to October. This mushroom is also becoming increasingly common in Australia and New Zealand where it is likely introduced. - Chalciporus piperatus, commonly known as the peppery bolete, is a small pored mushroom of the family Boletaceae found in mixed woodland in Europe and North America. It has been recorded under introduced trees in Brazil, and has become naturalised in Tasmania and spread under native "Nothofagus cunninghamii" trees. A small bolete, the fruit body has a orange-fawn cap with cinnamon to brown pores underneath, and a high by thick stipe. The rare variety "hypochryseus", found only in Europe, has yellow pores and tubes. - Xerocomus is a genus of fungi that is related to Boletus . Many mycologists do not recognize the distinction ; however , several molecular studies have demonstrated that they are two distinct genera , with clear morphological differences . The genus Xerocomus has been further divided into Xerocomellus and Hemileccinum by Sutara ( 2008 ) . The members of the Xerocomellus genus are more closely related to Boletus than true Xerocomus is , which is relatively distantly related to Boletus and more closely related to Phylloporus . Other former Xerocomus species have been moved to Aureoboletus , Imleria , Hortiboletus and Rheubarbariboletus . Most members of Xerocomus are edible . Ladurner and Simonini published a monograph on Xerocomus in 2003 . In 2008 , Hills included 18 species found in Britain , not including some species sometimes treated as Xerocomus , including Boletus pulverulentus and Boletus impolitus . Molecular phylogenetic studies strongly imply that Xerocomus is a heterogeneous genus of polyphyletic origin . - Petter Adolf Karsten (16 February 1834 22 March 1917) was a Finnish mycologist, the foremost expert on the fungi of Finland in his day, and known in consequence as the "father of Finnish mycology". - A genus (genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. - In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs. - Binomial nomenclature (also called binominal nomenclature or binary nomenclature) is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example, humans belong to the genus "Homo" and within this genus to the species "Homo sapiens". The "formal" introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work "Species Plantarum" in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book "Pinax theatri botanici" (English, "Illustrated exposition of plants") many names of genera that were later adopted by Linnaeus. - Tylopilus is a genus of over 100 species of mycorrhizal bolete fungi separated from "Boletus". Its best known member is the bitter bolete ("Tylopilus felleus"), the only species found in Europe. More species are found in North America, such as the edible species "T.alboater", and the tropics. Australia is another continent where many species are found. All members of the genus form mycorrhizal relationships with trees. Members of the genus are distinguished by their pinkish pore surfaces. - The Boletaceae are a family of mushrooms, primarily characterized by developing their spores in small pores on the underside of the mushroom, instead of gills, as are found in agarics. Nearly as widely distributed as agarics, they include the Cep or King Bolete ("Boletus edulis"), much sought after by mushroom hunters. As a whole, the typical members of the family are commonly known as boletes. - Boletus is a genus of mushroom-producing fungi, comprising over 100 species. The genus "Boletus" was originally broadly defined and described by Carl Linnaeus in 1753, essentially containing all fungi with pores. Since then, other genera have been defined gradually, such as "Tylopilus" by Petter Adolf Karsten in 1881, and old names such as "Leccinum" have been resurrected or redefined. Some mushrooms listed in older books as members of the genus have now been placed in separate genera. These include such as "Boletus scaber", now "Leccinum scabrum", "Tylopilus felleus", "Chalciporus piperatus" and "Suillus luteus". More recently, "Boletus" has been found to be massively polyphyletic, with only a small percentage of the over 300 species that have been assigned to "Boletus" actually belonging there and necessitating the description and resurrection of many more genera. - Suillus luteus is a bolete fungus, and the type species of the genus "Suillus". A common fungus native to Eurasia, from the British Isles to Korea, it has been introduced widely elsewhere, including North and South America, southern Africa, Australia and New Zealand. Commonly referred to as slippery jack or sticky bun in English-speaking countries, its names refer to the brown cap, which is characteristically slimy in wet conditions. The fungus, initially described as "Boletus luteus" by Carl Linnaeus in 1753, is now classified in a different family as well as genus. "Suillus luteus" is edible, though not as highly regarded as other bolete mushrooms, and is commonly prepared and eaten in soups, stews or fried dishes. The slime coating, however, may cause indigestion if not removed before eating. - Aureoboletus is a genus of bolete fungi in the family Boletaceae. It was circumscribed by Czech mycologist Zdenk Pouzar in 1957. A taxonomic monograph was published in 2010 by Wolfgang Klofac. What is the relationship between 'xerocomus' and 'boletaceae'?
