Boletus Coniferarum
''Boletus coniferarum'', the conifer bolete, is a mushroom of the genus ''Boletus'' native to North America. The species is inedible due to its extremely bitter taste. The semi-velvety cap is grayish and the yellow tubes stain dark blue. The stipe is yellowish, darkening in age, and sometimes larger near the base. The flesh is buff and stains blue. ''Boletus frustosus'' is similar, but has reddish hues at the bottom of the stipe, as does ''Cyanoboletus pulverulentus'', which stains a greener hue than ''B. coniferarum'' and tastes mild.

Mushroom
A mushroom or toadstool is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground, on soil, or on its food source. ''Toadstool'' generally denotes one poisonous to humans. The standard for the name "mushroom" is the cultivated white button mushroom, '' Agaricus bisporus''; hence the word "mushroom" is most often applied to those fungi ( Basidiomycota, Agaricomycetes) that have a stem ( stipe), a cap ( pileus), and gills (lamellae, sing. lamella) on the underside of the cap. "Mushroom" also describes a variety of other gilled fungi, with or without stems, therefore the term is used to describe the fleshy fruiting bodies of some Ascomycota. These gills produce microscopic spores that help the fungus spread across the ground or its occupant surface. Forms deviating from the standard morphology usually have more specific names, such as " bolete", " puffball", " stinkhorn", and "morel", and gilled mushrooms themselves are often called " agarics" in ...

Boletus
''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 hymenial pores instead of gills. 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''. Most boletes have been found to be ectomycorrhizal fungi, which mean that they form a mutualistic relationship with the roots system of certain kinds of plants. 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 ''Boletu ...

Boletus Frustosus
''Caloboletus frustosus'' is a bolete fungus native to North America. Until 2014, it was known as ''Boletus frustosus''. Recent changes in the phylogenetic framework of the family Boletaceae prompted the transfer of this species, along with several other related boletes, including ''Caloboletus calopus'', to the genus ''Caloboletus''. It was first described scientifically in 1941 by mycologists Wally Snell and Esther Dick. See also *List of North American boletes __NOTOC__ This is a list of bolete species found in North America. Bolding of the species name, and an asterisk (*) following indicate the species is the type species of that genus. '' Aureoboletus'' *''Aureoboletus auriporus'' *''Aureoboletus ...

Cyanoboletus Pulverulentus
''Cyanoboletus pulverulentus'', commonly known as the ink stain bolete, is an edible bolete mushroom. It is found in deciduous and mixed forests, particularly on moist soil on slopes and under beech and oak trees. A common species, it is found in northern Asia, Europe, North Africa, Central and northern South America, and eastern North America. All parts of the mushroom will stain dark bluish-black after handling. A recent study has revealed this mushroom hyperaccumulates arsenic and therefore it's consumption should be limited. Taxonomy ''Boletus pulverulentus'' was first described by German mycologist Wilhelm Opatowski in 1836. The specific epithet ''pulverulentus'' means "covered with powder" and refers to the somewhat dry powdery surface of the young cap and stalk. The fungus was transferred to the newly created genus '' Cyanoboletus'' in 2014, where it is the type species. Based on the 28S rDNA, North American collection of this fungus reported in the Genbank database (acc ...

List Of Boletus Species
The following is an incomplete list of species of the mushroom genus ''Boletus''. The genus has a widespread distribution and contains about 300 species. However, the genus is polyphyletic, and approximately only 10 percent of the described species are actually members of the Boletus ''sensu stricto'' clade (Singer's ''Boletus'' section ''Boletus'', also known as the "Porcini Clade").

Fungi Described In 1949
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true fu ...
