Referred to by ATel #: 8707

We report optical spectroscopy of 14 supernovae discovered by the Dark Energy Survey (ATel #4668). The spectra (425-1050nm) were obtained using LDSS3 on the 6.5m Clay telescope at the Las Campinas Observatory. Object classification was performed using SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and superfit (Howell et al, 2005, ApJ, 634, 119), the details of which are reported in the table below.
