Xerocomus
''Xerocomus'' is a genus of poroid fungi related to '' Boletus''. Many mycologists did not originally recognize the distinction between the two genera and placed ''Xerocomus'' taxa in genus ''Boletus''. However, several molecular phylogenetic studies have demonstrated that ''Xerocomus'' is a heterogeneous genus of polyphyletic origin, which has resulted in further division of ''Xerocomus'' into ''Xerocomellus'' and ''Hemileccinum''. The members of the genus ''Xerocomellus'' 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 since been moved to '' Aureoboletus'', ''Imleria'', ''Hortiboletus'' and ''Rheubarbariboletus''. Ladurner and Simonini published a monograph on ''Xerocomus'' in 2003, but this predated the taxonomical revisions based on phylogenetic inferences. In 2008, Hills included 18 species found in Britain, not in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Xerocomus Subtomentosus
''Xerocomus subtomentosus'', commonly known as suede bolete, brown and yellow bolete , boring brown bolete or yellow-cracked bolete, is a species of bolete fungus in the family Boletaceae. The fungus was initially described by Carl Linnaeus in 1753 and known for many years as ''Boletus subtomentosus''. It is edible, though not as highly regarded as other bolete mushrooms. It occurs throughout Eurasia, North America and Australia and grows with a wide range of hardwood and conifer trees. It forms symbiotic ectomycorrhizal associations with living trees by enveloping the tree's underground roots with sheaths of fungal tissue. The fungus produces spore-bearing fruit bodies. The olive to tan fruit body cap is up to in diameter and has a distinctive velvety surface. Like other boletes, it has tubes extending downward from the underside of the cap, rather than gills; spores escape at maturity through the tube openings, or pores. The pore surface is yellow and bruises blue. The stip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xerocomellus
''Xerocomellus'' is a genus of fungi in the family Boletaceae. The genus, as it was described in 2008, contained 12 species. However '' X. rubellus'' and '' X. engelii'' were transferred to the new genus '' Hortiboletus'' and '' X. armeniacus'' was transferred to the new genus ''Rheubarbariboletus'' in 2015. Molecular analysis supports the distinction of ''Xerocomellus'' species from ''Boletus'' and ''Xerocomus'', within which these species were formerly contained. ''Xerocomellus'' in fact is only distantly related to ''Xerocomus'' and is most closely related to ''Tylopilus'', ''Boletus'' sensu stricto, ''Porphyrellus'', ''Strobilomyces'', and ''Xanthoconium''. Taxonomy Members of the genus had been classified either in the genus ''Boletus'' or ''Xerocomus'' until Czech mycologist Josef Šutara examined a number of species and concluded that there was a defined group containing ''X. chrysenteron'', ''X. armeniacus'' and relatives that are distinct morphologically f ...

Boletus Impolitus
''Hemileccinum impolitum'' is a basidiomycete fungus of the family Boletaceae, native to Europe. It is commonly referred to as the iodine bolete, because its fruit bodies tend to emit an iodine odour when cut, more detectable in the stem base or overripe specimens. Like other members of the family, ''H. impolitum'' has tubes and pores instead of gills in the hymenial surface of its fruit bodies. It is widely distributed in temperate and southern Europe, where it grows in mycorrhizal symbiosis with broad-leaved trees, particularly oak (''Quercus''). Taxonomy and phylogeny The iodine bolete was first described by Elias Magnus Fries, an eminent mycologist of the 19th century, who placed the fungus in genus ''Boletus''. The Latin epithet ''impolitum'' (meaning "rough"), likely refers to the cap of the species, which is initially felty and covered in a finely filamentous coating when viewed under a magnifying glass. The species' taxonomic position had long remained uncertain and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boletaceae
The Boletaceae are a family of mushroom-forming fungi, primarily characterised by small pores on the spore-bearing hymenial surface (at the underside of the mushroom), instead of gills as are found in most agarics. Nearly as widely distributed as the agarics, the family is renowned for hosting some prime edible species highly sought after by mushroom hunters worldwide, such as the cep or king bolete (''Boletus edulis''). A number of rare or threatened species are also present in the family, that have become the focus of increasing conservation concerns. As a whole, the typical members of the family are commonly known as boletes. Boletes are a group of mushrooms reasonably safe for human consumption, as none of them are known to be deadly to adults. Edible bolete species are especially suitable for novice collectors, since they pose little danger of being confused with deadly poisonous mushrooms, such as deadly ''Amanita'' species which bear gills instead of pores in their ...

Hemileccinum
''Hemileccinum'' is a genus of fungi in the family Boletaceae. It was erected in 2008 by Josef Šutara to contain two species united by a number of shared morphological features: '' H. depilatum'' and the type '' H. impolitum''. In 2014, Wu ''et al.'' found it to be distinct from other bolete genera in a molecular phylogenetic study and found it to be most closely related to '' Corneroboletus''. In 2015, '' H. subglabripes'' was transferred to ''Hemileccinum'' from ''Boletus'' based on DNA evidence, while subsequent studies further confirmed the monophyly In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants.

Rheubarbariboletus
''Rheubarbariboletus'' is a fungal genus in the family Boletaceae. Circumscribed in 2014, it contains two species found in Europe: ''Rheubarbariboletus persicolor'', and the type, '' R. armeniacus''. The generic name is derived from the Latin ''rheubarbarum'', meaning "rhubarb", referring to the color of the flesh at the base of the stipe. The genus is closely related to '' Xerocomellus'', but differs by having smooth spores, the unchanging yellowish to orange-rhubarb coloring of the stipe base, and the distinctive dark-green to black color reaction with iron sulphate on both the surface of the cap and on the flesh of the stipe. ''Rheubarbariboletus persicolor'' was originally described in 1996 as ''Xerocomus persicolor'', based on collections made in Italy. The bolete was found in mixed woodland with hop-hornbeam, pine, and oak An oak is a tree or shrub in the genus ''Quercus'' (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imleria
''Imleria'' is a genus of fungi in the family Boletaceae. It was erected in 2014 by Alfredo Vizzini as a new genus for what had previously been named ''Boletus badius'' or ''Xerocomus badius''. It was placed in its own genus because of its distinct morphological features and because it had previously been found to belong in its own genus in a molecular phylogenetics study by Gelardi ''et al.'' (2013). Zhu ''et al.'' (2014) placed three more species in ''Imleria''. Species of ''Imleria'' can be found in Europe, North America and Asia. The genus is named in honor of Belgian mycologist Louis Imler (1900–1993).
