Bonsoir tousthis recent thread: http://www.ascofrance.com/search_forum/26596 encouraged me to examine fallen leaves of Prunus laurocerasus. In a small area of woodland in suburban Huddersfield I collected a fallen, but still green in places, leaf. Subsequent examination showed it to be Eupropolella britannica. Asci were at various stages of development, including ones with spores up to 2-septate (possibly hinting at 3-septate), but only a few spores were beginning to turn brown (bottom centre image).
I note that Zotto has two collections - HB6237 & HB6372 (same digits - strange ;-)) tentatively under Eupropolella "hederae". He quotes Marijke Nauta as stating this is not a typical Eupropolella: does anyone have any further information regarding why? It seems from my collection that it can grow as a partial parasite, in fact it reminded me of the parasitic Schizothyrioma ptarmicae, which I have collected several times on living Achillea ptarmica leaves and stems. For what it is worth Zotto's collection HB6372 does look good for E. britannica, as he himself suspects I see.
Cordialement

Re : Eupropolella britannica
Many thanks, Chris! What I originally believed is that E. britannica differs from my fungus on Hedera in a much darker excipulum. Now I see that Susana's (V.2013) and Enrique's (V.2010) collections on Hedera are also dark, so maybe this is variable.
Croziers were seen on both substrates, spore size is quite the same. But why on earth does this fungus grow on two very different genera? Only because the leaves are leathery?
Would be a nice object for a DNA-analysis, together with Trochilas.

Re : Eupropolella britannica
@ Zotto I agree it is strange, especially as this seems to be able to produce spores on partially living leaves, which would tend to suggest an even stronger host specificity; only occasionally does one come across something which can jump the gaps - like Aulographum hederae, recorded in the UK on Ilex, Hedera and Rhododendron.
@Hannie please feel free to download the image (and thank you for the courtesy of asking :-) )
@Thomas I'll contact Jens
