I found these on some Carex yesterday.
They are 1-5mm wide and 3-5 mm high.

Re:Gelatinous on Carex
Good find!!
The top cell contains a VB, i.e. a refractive vacuole (like in Mollisia). If you add KOH or MLZ these VBs disappear, also in the herbarium.
This species is Ombrophila pileata (= Hymenoscyphus pileatus). Gel and apical ring tpye clearly exclude Hymenoscyphus, still the current name in IF (although I corrected to Ombrophila already in 1985). The problem is only that in Karsten's type material which I studied is a mixtum: it contains also a very similar species with distinctly smaller and narrower and rather strongly curved spores, O. lacustris. regrettably, Karsten's is not clear in this point, giving +/- both spore types. So I have to select one of them as lectotype.
