Pseudophacidium ?necans on Vaccinium myrtillus

I am curious to hear your opinion on this material collected on Vaccinium myrtillus. Morphologically, it seems to correspond to Pseudophacidium necans, but Vaccinium is usually the host for P. ledi.
However, my material deviates from P. ledi in the following characteristics, which all fit better for P. necans:
ascospores: 11-17 x 5.7-7.8 µm;
asci: in living state up to 180 µm, dead at least 130 µm;
inner cells of the cover layer: generally inflated, globose to pyriform (but often variable).
The last 3 photos show the presumed anamorph.
Best wishes,
Gernot

Re : Pseudophacidium ?necans on Vaccinium myrtillus
Hello, André!
Thank you for pointing out this thread. I did read it before I posted my collection. I am mostly wondering about the host because it seems unusual for P. necans.
In the meantime I collected another specimen on Ericaceae (most likely Calluna vulgaris) which I attach here (the last photo shows conidia). Again, the shape of the ascospores differs significantly from a previous collection of mine on Rhododendron ferrugineum: http://ascofrance.com/search_recolte/4476. It seems to me that more than one Pseudophacidium species occurs on Ericaceae.
Best wishes,
Gernot
