Asco on Equisetum

Some years ago I collected a fungus on Equisetum palustre. Based on spore measurements in Ellis and Ellis I tentatively named it Mycosphaerella equiseti (Fuckel) Schröter. Since then and having read the paper Nordic equiseticolous Pyrenomycetes by Lennart and Kerstin Holm, in Nordic Journal of Botany (1) pp. 109-119, I suspect this may be their unnamed "Didymella sp." (see the PDF attachment); the characteristic spore shape is very similar, and does not match the Mycosphaerella; the spores of my collection are somewhat larger than their dimensions, but they do talk of their material being "limited".I would be interested if anyone has any comments on this.
Amitiés
Chris

Re : Asco on Equisetum
Yes, you have probably found the Didymella sp. of L. Holm, surely a equiseticolous Didymella.

Re : Asco on Equisetum
Thanks for comments/questions Alain and Yan.
Spore measurements can be deduced from the scale bar, the spores were hyaline; I do not have measurements of pseudothecia or asci. I am hoping that I have retained material from the original collection which I can re-examine.
Yesterday (6th) I have collected more dead Equisetum palustre stems from the same area so perhaps I will have more material of this fungus . . . .
