D. Drehmel et al., Molecular phylogeny of Amanita based on large-subunit ribosomal DNA sequences: implications for taxonomy and character evolution, MYCOLOGIA, 91(4), 1999, pp. 610-618
Phylogenetic relationships in the genus Amanita were investigated using seq
uence data fr-om the nuclear-encoded large subunit ribosomal DNA. Exemplar
taxa were selected to represent the all sections from the current classific
ations of Singer, Bas and Jenkins. Phylogenetic analysis of the nuc-LSU reg
ion supports the taxonomic distinction of subgenera Amanita and Lepidella,
as well as all nine sections previously recognized by Singer (R. Singer, 19
86, The Agaricales in Modern Taxonomy, 4th ed.) including sections Amanita,
Amidellae, Caesareae, Lepidella, Mappae, Phalloideae, Ovigerae, Vaginatae,
Validae. Phylogenetic analyses among these nine terminal groups reveal sev
eral higher-level relationships which are also supported by morphological a
nd biochemical characters. A phylogenetic classification is proposed which
recognizes two subgenera (Amanita, Lepidella), four sections (Amanita, Vagi
nate, Phalloideae, Lepidella), seven subsections (Amanita, Ovigerae, Amidel
lae, Caesareae, Phalloideae, Vaginatae, Validae), and two series (Mappae, V
alidae).
