Gelatinous on Carex

Hi,

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

Re:Gelatinous on Carex
The spores are 16-30x3-4 containing some small droplets.
Asci are 75-95x8-10, IKI+ and paraphyses are 2-3 mm wide, septate and may be a little longer than asci.
The top cell of the paraphyses is somehow different, maybe it's walls are thicker or something.

One photo more.
I just studied a little piece of the fungi and there were very little to see of the cells.

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.
