Phylogenetic Species Recognition and Species Concepts in Fungi

Use of the Genealogical Sorting Index (GSI) to delineate species boundaries in the Neofusicoccum parvum–Neofusicoccum ribis species complex

“…Which should take precedence? A species concept explains the type of entity described as a species, whilst species recognition criteria details the requirements an entity must have in order to belong to the same species (Paul, 2002;Taylor et al, 2000). A species recognition concept must provide the operational tools that distinguish between species.…”

“…Whilst N. cordaticola has achieved monophyly at all four loci. However, the conferral of species status is dependent upon the consensus across multiple gene trees (Taylor et al, 2000). In a study of mouse lemurs (Weisrock et al, 2010), species were identified with the aid of the GSI despite little evidence of monophyly amongst individual gene regions.…”

“…This situation is probable for recently diverged species or those when barriers to gene flow have not been fully developed. Taylor et al (2000) encourages the use of multiple concordant gene genealogies to delineate species. This approach has been used to identify four other species within the N. parvum-N. ribis complex (Begoude et al, 2010;Pavlic et al, 2009a) and in other fungal species (O'Donnell et al, 2004;Villalta et al, 2009).…”

“…Neofusicoccum cordaticola, Neofusicoccum kwambonambiense and Neofusicoccum umdonicola (Pavlic et al, 2009a), and Neofusicoccum batangarum (Begoude et al, 2010). These species were recognised using the genealogical concordance phylogenetic species recognition concept (GCPSR) which is a modified form of the phylogenetic species concept (Taylor et al, 2000). These four new species were separated based on fixed sequence polymorphisms located within up to five gene regions and appear to have undergone morphologically static cladogenesis i.e.…”

A review on research advances, issues, and perspectives of morels

“…Development of Genealogical Concordance Phylogenetic Species Recognition (GCPSR) (Taylor et al 2000) provided a consensus criterion for resolving species relationships among fungi, including those of morels (Dettman et al 2003; Revankar and Sutton 2010; Taşkın et al 2010, 2012; O’Donnell et al 2011; Du et al 2012a; Zeng et al 2013; Elliott et al 2014; Pildain et al 2014; Voitk et al 2014). …”
