Only reference I have is in Lichens of North America, and that just says “mainly on siliceous rocks in the upper tidal zone continuing into the spray zone”. Certainly doesn’t sound like your locality, but given the word “mainly”, it doesn’t rule anything out! :) (It also mentions “a black Verrucaria common on dry limestone is V. nigrescens”.)
If V. maura is exclusively found right above the waterline, maybe this a darker form of V. nigrescens.
I think V. maura is exclusively found there.

Thanks anyway, Jason.
