Corinectria, a new genus to accommodate Neonectria fuckeliana and C-constricta sp nov from Pinus radiata in Chile

Corinectria gen. nov. is described for C. constricta sp. nov., C. fuckeliana comb. nov. and C. tsugae comb. nov. The new genus is distinguished from Neonectria sensu stricto on the basis of morphological differences and biology. The species in Corinectria are only known from conifers from the Northern and Southern Hemispheres. The phylogenetic analyses of five loci (ACT, ITS, LSU, RPB1, TEF1) support the monophyly of the new genus, and those based on ACT, BTUB and TEF1 support the segregation of the new species. Corinectria constricta was previously reported as Neonectria cf. fuckeliana, causing cankers in Pinus radiata plantations in Chile.
