Nectriopsis rubefaciens?

I found a (lichenicolous?) fungi growing on thallus of Parmelina pastillifera. From a macro perspective, they look like Nectriopsis rubefaciens: small fuiting bodies wit perithecial hairs. However, the spores I sofar see in my samples are not corresponding with the spores of N. rubefaciens. The are 1-celled, 12,1 - 15,9 x 2,5-3,2 micrometer (1 div = 2,9 um).
Does anyone know what species this is? Thanks in advance!
Kind regards,
Niek Schrier

Re : Nectriopsis rubefaciens?
The determination is correct! The actual name is Trichonectria r. now, due to some marginal discriminating features to Nectriopsis, (which has not been valuated by gen sequences until now).
To my knowledge, Parmelina pastillfiera is a new host lichen!

Re : Nectriopsis rubefaciens?
Thank you for the conformation Franz! So the spores can variate for this species? Or are these undeveloped 1-celled spores which become the 2-celled spores I see in documentation about this species?
I also cound not find any note for this species hosting on Parmelina pastillfiera, but did read it hosts on Parmeliaceae, indicating it has a lot of hosts to choose from.

Re : Nectriopsis rubefaciens?
It was supposed by some authors, that T.rubefaciens could be an agglomerate of species. There are not so many hosts known till now, mostly it was found on Parmelia sulcata and P.saxatilis agg. I have a collection on Flavoparmelia caperata with much longer ascospores, affirming this hypothesis. And one on Parmelina tiliacea.
1-celled ascospores might be very young ones or mature broken into 2 parts. Irregularities can be observed sometimes, Not only in T.rubefaciens.
Keep an eye on this specimen. I was informed recently, that a working group in Krakau is starting to investigate Hypocreales in nearer future.
