Originally the two dried Simmonds cultures were in the same PDD packet as PDD 28797. When this was designated the epitype specimen of Colletotrichum queenslandicum J.H. Simmonds 16347A2 was split into a new PDD specimen as PDD 111073. Thus J.H. Simmonds 11663C = PDD 28797 = ICMP 1778 ; J.H. Simmonds 16347A2 = PDD 111073 = ICMP 1780.
