Xerocomus Mcrobbii
''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 including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungus
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 f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
