related to any oxygenic phototrophs (closest cultured isolate match  \textit{Vampirovibrio chlorellavorus}, 95\% sequence identity,  Table~\ref{tab:cell}). A sister clade to the oxygenic phototrophs classically  annotated as ``cyanobacteria'' in SSU rRNA gene reference databases databases,  but does not possess any known phototrophs phototrophs,  has recently been proposed to constitute its own phylum, "Melainabacteria" \citet{Di_Rienzi_2013}. Although \citet{Di_Rienzi_2013}; although,  the phylogenetic position of ``Melainabacteria'' is debated \citep{Soo_2014}. The catalog of  metabolic capabilities associated with cyanobacteria (or candidate phyla  previously annotated as cyanobacteria) are quickly expanding  \citep{Di_Rienzi_2013, Soo_2014}. Our findings provide evidence for cellulose degradation within a lineage closely related to but apart from oxygenic  phototrophs. Notably, polysaccharide degradation is suggested by an analysis of  a ``Melainabacteria'' genome \citep{Di_Rienzi_2013}. Although we highlight
