A new Ceratocystis species defined using morphological and ribosomal DNA sequence comparisons
TL;DR: Morphological comparisons showed that the Ceratocystis isolates from A. mearnsii have light-coloured perithecial bases and divergently arranged ostiolar hyphae compared with entirely black perithecia and convergently arranged Ostiolar Hyphae of typical C. fimbriata isolate.
