Excellent, and looks right. Mushroom Observer states:
It can be distinguished from two other common jelly fungi, D. palmatus and Tremella mesenterica by its smaller size and shape, appearing as individual spheres rather than in convoluted lobes.

More info from this excellent site:
D. stillatus has two stages. The arthrosporus stage, or the vegetative stage, has bright orange or reddish frutications. It is usually the first to appear and has smaller fruit bodies, which are reguarly hemispherical, dark reddish orange, and opaque due to the dense outer layer consisting largely of closely and irregularly packed arthrospores, or vegetative spores. These spores are formed from vegetative hyphal tissue, or the everyday tissue that comprises the fungus. This stage is quite firm but elastic, with a solid consistency.

The basidiferous stage, or reproductive stage, is bigger and more irregular and lobed, because the surface layer is thrown into a few relatively coarse convoluted folds and also because small group so neighboring fruit bodies coalesce and stick together. This reproductive stage appears to be pale yellow and semi-translucent due to the lack of the thick layer of arthrospores. It has instead basidiospores, which are formed on specialized reproductive structures called basidia that occur in the phylum Basidiomycota. This stage is gelatinous, not distinctly rooted, but attaches to the substrate by a central point.

I think I have managed to get the two stages in the two pics!
