Hymenoscyphus with squarrulose stem

In Tilia, Quercus, Corylus forest on calcareous soil in Oslo region, Norway. On dead deciduous wood (twig). Stems of apothecia brown-squarrulose. Spores 15(-17)x(3.5-)4(-5) micr, multiguttulate with an aguttulate central region, eventually becoming 1-septate. Paraphyses multiguttulate, ca. 8 micr. across. Asci 8-spored, IKI- (Lugol). Can Hymenoscyphus have a stem like this?

Re : Hymenoscyphus with squarrulose stem
IKI- I would not believe, are you sure? It reminds me of H. virgultorum as I interpret that species. I think characteristic are the spores with only small LBs. Croziers should be absent in that species.

Re : Hymenoscyphus with squarrulose stem
Thanks, Zotto. I expected you would not believe it. I was surprised myself. I will check again. Is this type of stem typical/common in H. virgultorum? I did not see croziers, correct.

Re : Hymenoscyphus with squarrulose stem
I think in H. scutula can it occur as well as in H. macroguttatus, though perhaps not as prominent as in your find. Anyway I doubt if it is constant.

Re : Hymenoscyphus with squarrulose stem
You were of course right. I tested with Baral'sche Lösung and I see a weak blue ring/pore in some asci. I wonder if my Lugol has lost its potency. What is your experience with this? It is stored in a tiny dark brown bottle, but it's several years old (I don't do ascos every day).
Thanks again!
Thanks again!

Re : Hymenoscyphus with squarrulose stem
You see it at the colour, it must be brown in a hyaline bottle, not pale yellow.

Re : Hymenoscyphus with squarrulose stem
OK. Yes there is a distinct colour difference between the Baral'sche and the Lugol bottle.
