Hi to allThis Phaeohelotium (¿) species grews on semiinmersed hardwood in montaneous streams (700-800 m).
The ascomata are small (up to 1 mm) and subsessile from a very short and conical stem.
The hymenium is bluish grey, lilac, later withish. The ectal excipulum of very young apothecia is ligth brownish.
Have you any idea?
Many thanks
Enrique

Re:Phaeohelotium
Asci seem to be with croziers. I see no difference to Ph. imberbe / Hymenoscyphus imberbis.

Re:Phaeohelotium
Yes, Zotto. Asci have croziers. I'm sorry, I was wrong for the strange color of the ascomata, without reddish colors. I have tested the blue reaction of the apothecial base, and see that is bluish in IKI.
Many thanks
