Well ,3014X Black Ischia, Sugests a Hybrid of Black ischia Female breba fruit,with male caprifig polen,Fig #3014.
That is How all Hybrids of other figs are described at UC Davis Germaplasm.
It is also,possibly it was described by mistake 3014 X Black Ischia,Maybe 3014,stands for the street number of the original owner,of an original Ischia Black fig,LOL.
By Contrast Black Ischia,is an old cultivar and can be found at UCD at DFIC 90 Black Ischia,and is not a hybrid.
Black Ischia X Mission X Kearney,is another Black Ischia Hybrid and can be found ,under # DFIC 94
