This is the cause of the most common, familiar, widespread and destructive shot-hole disease of the cherry and plum. When on the peduncles the fruits are dwarfed and ripen imevenly. The diseased leaf tissue usually falls away, resulting in "; Acervuli abound. Arthur found a Phoma associated with this fungus and later asci in the same pycnidia. He believed these forms all con-.
