Which genus was described first, Ixiolirion or Allosyncarpia?
Ixiolirion Ixiolirion is a genus of flowering plants native to central and southwest Asia, first described as a genus in 1821. Recent classifications place the group in the monogeneric family Ixioliriaceae in the order Asparagales of the monocots. In earlier systems of classification, it was usually placed in the family Amaryllidaceae.
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".
