Hymenoscyphus ombrophiliformis?
Åke Widgren,

Hello,I found this one in October last year, on rutten leaves of Carex elata, on the bank of a small stream (Blekinge, southern Sweden). Unfortunately only a single fruit body, so I have microscoped just a small part of it. I´m quite sure it´s a Hymenoscyphus, and if so there are probably two alternatives - H. ombrophiliformis and H. syringaecolor. I think H. ombrophiliformis fits better, but the substrate maybe a bit odd? Are there any other alternatives?
Fb: about 4 mm wide, 2,5 mm high.
Color: purple
Spores: (17,9-) 19,3-21,5 (-22,5) x 4,5-5,0 um. Me = 20,4 x 4,8. Qe = 4,3.
Asci: about 140-155 um long.
Paraphyses: filiform and septated, with small vacuoles.
I am grateful for your comments. Any help will be appreciated.
Best regards,
Åke

Re : Hymenoscyphus ombrophiliformis?
Hi Ake,
Did you test IKI (Lugol) on asci apex ? This would give an essential character to a Hymenoscyphus possibility and would reject - or not - an Ombrophila species , which I suspect.
