Lanzia equiseti?

Found these on dead stems of Equisetum fluviatilis standing in water near a slow stream in central Sweden yesterday. Hymenoscyphus seemed probable but the spores where large and "weird".
Spores: (29-)30(-32)x(6-)7,5µm
Asci ~130-150µm
Most things are very similar to Marja Pennanens collection from 2010 (http://www.ascofrance.com/search_forum/12546). Can anyone confirm the species, seems to be first collection for Sweden.

Re : Lanzia equiseti?
Hello Johan,
I do not know what "Lanzia" equiseti is - but your collection looks like a member of the Hymenoscyphus caudatus-complex to me.
Best regards, Lothar

Re : Lanzia equiseti?
There is a "Hymenoscyphus" equiseti, described by Raitviir 1984 as Lanzia equiseti.

Lothar, look at Hymenoscyphus folder in Zotto's Drive.

Re : Lanzia equiseti?
I confirm L. equiseti which has a Hymenoscyphus-type of apical ring, so cannot belong in Lanzia. The spores of this species are not really scutuloid, although those of H. caudatus are also only slightly so. They have an extraordinary size, in any case.
A sequence of an isotype of L. equiseti from Karelia gained by Kadri Pärtel showed that this is a Helotiaceae but not a Hymenoscyphus in the narrow sense. So a very interesting matter.

PS. I must correct myself, the spores are indeed slightly to distinctly scutuloid here, while in the type and Marja's sample they are only very indistinctly so.

Re : Lanzia equiseti?
Dear Johan
I am preparing a description of H. equiseti, and I wonder if you have more photos. Especially a mature ascus (you posted only the ascus base).
Important would be to include a scale to your photos. I also wonder about apothecial size and stipe length, data necessary in a description.
Danny Haelewaters obtained a sequence, and we want to prepare a small contribution within a joint larger publication of various authors.
