Hello
I want to ask you if you have found this year or in the last years Hymenoscyphus phiala on Alnus twigs. It is not rare and easily recognizable, but its nomenclature is very unclear. Besides, it is not clear if it is a Hymenoscyphus or perhaps a Cyathicula or Bisporella because of the heavily gelatinized ectal excipulum.
If you have preserved a specimen in the past years, I would be happy if a sequence could be obtained from it. To my knowledge there is no DNA available.
The original illustration in Flora Danica could represent a Hymenoscyphus indeed, but the aposize stated by Saccardo 1889 gives too large disc diameters of of 4-7 mm, unlike our fungus which has around 1-2.5 mm. What Rehm 1893 named H. phiala (from Wannsee, Sydow) has large oil drops in the spores and faintly amyloid ascus tips. I guess it was something like H. calyculus what Rehm (and perhaps also Vahl) was dealing.
Thanks
Zotto
