Botryosphaeriacea are important pathogens on a variety of woody hosts, including almond, a major crop in California. Almond is susceptible to Botryospharia dothidea that forms band cankers on almond trunks, and the same fungus was also isolated from cankers of the canopy. To study the diversity and host range of B. dothidea and allied species from almond we used 132 isolated from 36 plant almond five continents, including 45 strains from almond in California. Species were identified by comparison to 13 ex-type strains with phylogenetic analyses based on six loci, including the internal transcribes spacer (ITS) regions of the nuclear ribosomal RNA gene repeat and portions of the nuclear ribosomal RNA gene repeat I-alpha, glyceraldehyde-3-phosphate dehydrogenase, heat shock protein, histone-3 and betatubulin.
