Updated project metadata. We describe thephosphoproteome of filamentous fungus Aspergillus nidulans. Phosphopeptides were enriched using affinity enrichment using titanium dioxide and separated using a convenient ultralong gradient separations on c18 reverse phase columns. Over 1637 phosphopeptides corresponding to 647 phosphoproteins were identified using using a “high-high” strategy using HCD on the novel Q-exactive platform
