We report optical spectroscopy of supernova candidates discovered by the Dark Energy Survey. The spectra (420-950 nm) were obtained using LDSS-3C on the 6.5m Clay telescope at the Las Campanas Observatory on Nov 15, 2014. Object classification was performed using SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

1. Discovery magnitude in i-band. Phase is uncertain due to SN falling near a chip edge.
