Abstract:
The genus Caliciopsis (Eurotiomycetes, Coryneliales) includes saprobic and plant pathogenic species. Caliciopsis canker is caused by Caliciopsis pinea Peck, a species first reported in the 19 th century in North America. In recent years, increasing numbers of outbreaks of Caliciopsis canker have been reported on different Pinus spp. in the eastern USA. In Europe, the disease has only occasionally been reported causing cankers, mostly on Pinus radiata in stressed plantations. The aim of this study was to clarify the taxonomy of Caliciopsis specimens collected from infected Pinus spp. in Europe and North America using an integrative approach, combining morphology and phylogenetic analyses of three loci. The pathogenicity of the fungus was also considered. Two distinct groups were evident, based on morphology and multilocus phylogenetic analyses. These represent the known pathogen Caliciopsis pinea that occurs in North America and a morphologically similar, but phylogenetically distinct, species described here as Caliciopsis moriondi sp. nov. , found in Europe and at least one location in eastern North America. Caliciopsis moriondi differs from C. pinea in various morphological features including the length of the ascomata, as well as their distribution on the stromata.
