Where'd Augustine say spare excommunication when a sin is universal?

In Gillespie's notes on the Westminster assembly he says this about Augustine that I need to locate and I'm not having an easy time with the search: "So Augustine would have excommunication spared when the sin is universal."

 

[Phil D.]

Whitgift identifies it here, which appears in Augustine's works here

It is rather remarkable how even small changes within a search parameter can yield vastly different results...
