Bur oak blight (BOB) is a fungal disease that is relatively new to the plant pathogen landscape. BOB started to appear in Midwestern states in the 1990s. The first few diagnoses pointed to a common fungus, Tubakia dryina, as the culprit. However upon further research BOB was said to be caused by a new unnamed species of Tubakia, later named ‘’Tubakia iowensis T.C. Harr. & D. McNew sp. nov. ‘’ BOB has severe symptoms and is a serious new problem amidst the plant pathology world.
