Hello everybody, on decayed hardwood e.g. Quercus
Small perithecia on Oenanthe crocata

Bonjour
Please can someone help me with this identification?
Found on dead stems of Oenanthe crocata with some blackening of the tissues.
Mainly single perithecia with protruberant ostioles. Asci 90 microns , bitunicate, I think. Mature spores 13 - 16 x 5 microns with one septa. paraphyses cylindrical, 80 x 3 microns.
I thought it would be Leptosphaeria but the spores seem wrong for that. Maybe Diaporthe?
Can anyone recommend literature on taking good photomicrographs?
With thanks
Pauline Penna
