Phylogenetic species recognition and species concepts in fungi

Phylogenetic species recognition and species concepts in fungi. Fungal Genetics and Biology 31, 000-000. The operational species concept, i.e., the one used to recognize species, is contrasted to the theoretical species concept. A phylogenetic approach to recognize fungal species based on concordance of multiple gene genealogies is compared to those based on morphology and reproductive behavior. Examples where Phylogenetic Species Recognition has been applied to fungi are reviewed and concerns regarding Phylogenetic Species Recognition are discussed. (C) 2000 Academic Press.
