<Emphasis Type="Italic">Ceratocystis ficicola</Emphasis> sp. nov., a causal fungus of fig canker in Japan

The causal fungus of Ceratocystis canker of fig in Japan is described as Ceratocystis ficicola sp. nov. This species is characterized by galeated ascospores and is similar to Ceratocystis fimbriata sensu lato. However, the perithecia of the new species are much larger than those of C. fimbriata. The fungus grows more rapidly than C. fimbriata sensu stricto at 25°C but more slowly at 30°C. Molecular analysis of the nucleotide sequences of rDNA ITS regions showed that C. ficicola is phylogenetically placed in the clade of C. fimbriata s. l. but is easily distinguishable from other species of C. fimbriata s. l.
