Xerocomellus
Sign in to saveXerocomellus 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

Die Rotfußröhrlinge (Xerocomellus) sind eine Pilzgattung aus der Familie der Dickröhrlingsverwandten (Boletaceae). Sie waren bis 2008 Bestandteil der Filzröhrlinge (Xerocomus), wurden aber aufgrund neuer verwandtschaftlicher Erkenntnisse[1] in eine eigene Gattung gestellt.[2] Die Typusart ist der Gemeine Rotfußröhrling (Xerocomellus chrysenteron).[2] Inhaltsverzeichnis 1 Merkmale 2 Gattungsabgrenzung 2.1 Abgrenzung von den Filzröhrlingen 2.2 Abgrenzung von den Dickröhrlingen 2.3 Abgrenzung von Hemileccinum 3 Arten 4 Literatur 5 Einzelnachweise 6 Weblinks Merkmale Bei den Rotfußröhrlingen handelt es sich um Arten mit kleinen bis überwiegend mittelgroßen und häufig lebhaft gefärbten Fruchtkörpern.

== 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 from the group containing Xerocomus subtomentosus and related species. He deferred fully delimiting the genus until genetic work confirmed their distinctness. Previously, Manfred Binder had coined the term Paraxerocomus for the group but this was not officially published.
