Hydropisphaeria sp.

I found this ascomycete growing on stems of Equisetum arvense.
Perithecia size diameter is 200-230um. They are superficial, on a subiculum of hyphae; very easily removable. Color orange. When drying takes on a darker color and takes shape apotecioide.
The reaction is negative both KOH and the lactic acid.
Spores I see them smooth (I made stains with CB and RC and I have not seen any trace of ornamentation).
With the documentation that I have, I understand that this is Hydropisphaeria, and the key I have come to H.arenula, but the spore size would be too large.
That think?
regards
Susana

Re : Hydropisphaeria sp.
Yes I also think it is H. arenula. When I wrote with Christian the paper on Ijuhya equiseti-hyemalis, we treated also this species.
Spore size fits well. In H.B. 8622b, e.g., I measured 13.5-)16.5-#18-21#(-22.5) x 4.3-5.2(-5.8) µm
I also revised the type of Nectria equiseti-hiemalis showing spores in KOH (12-15-)16-22 x (3.2-)3.5-3.7(-4.2) µm. We confirmed its synonymy with H. arenula.
Do you have my paper? It is in Österr. Z. Pilzk. 17 (2008). I can send you a pdf.

Re : Hydropisphaeria sp.
Hi Zotto,
Thanks for the confirmation.
No, did not have the paper you mention, but I've seen that is available on the red and I've downloaded. Now I'll have a look.
Un saludo
