Syringopora sp. coral from the Martin formation of Arizona

I found one pebble of limestone from the Martin formation in Arizona that was shot through with a narrow, stick like coral that I believe is Syringopora sp. The genera is listed by Teichert in his paper and is illustrated by Langland in his article. The calices are very narrow, 3-5mm across and clustered but not in a central mass. Think of them more as loose spaghetti. My sample is small and there is not much exposed of the sides of individual calices, so could this possibly be a form of Aulocystis?

This specimen is from the Jerome member of the Martin formation (Devonian, Fransian stage) north of Payson, AZ.
