Abstract:Neonectria is a cosmopolitan genus and it is, in part, defined by its link to the anamorph genus Cylindrocarpon. Neonectria has been divided into informal groups on the basis of combined morphology of anamorph and teleomorph. Forty years ago, Booth divided Cylindrocarpon into four groups defined by presence or absence of microconidia and chlamydospores. Molecular phylogenetic analyses have indicated that Neonectria s. str. and Cylindrocarpon s. str. are phylogenetically congeneric. In addition, morphological and molecular data accumulated over several years have indicated that Neonectria s. lat. and Cylindrocarpon s. lat. do not form a monophyletic group and that the respective informal groups could represent distinct genera. In the present work a multilocus analysis (act, ITS, LSU, rpb1, tef1, tub) was applied to representatives of the informal groups to determine their level of phylogenetic support as a first step towards taxonomic revision of Neonectria s. lat. Results show five distinct highly supported clades that correspond to some extent with the informal Neonectria and Cylindrocarpon groups: (1) N. coccinea-group and Cylindrocarpon groups 1 & 4 (Neonectria/Cylindrocarpon s. str.); (2) N. rugulosa-group (Rugonectria gen. nov.); (3) N. mammoidea/N. veuillotiana-groups and Cylindrocarpon group 2 (Thelonectria gen. nov.); (4) N. radicicola-group and Cylindrocarpon group 3 (Ilyonectria gen. nov.); and (5) the anamorph genus Campylocarpon. Characteristics of the anamorphs and teleomorphs correlate with the five newly recognized genera. New combinations are made for species where their classification is confirmed by phylogenetic data.
