Re : Cf. Paraleptosphaeria
Hi, Bernard, 
This is very interesting collection, with Rosa is know only Leptosphaeria hazslinszkii, but it isn´t here. With the genus Paraleptosphaeria this can be only P. praetermissa, which growing on the Rubus and can also growth on another taxa with Rosaceae. Based to morphology of ascospores it belong to Leptosphaeria purpurea group. I don´t have to say, what it is, but I will like take to look on this your collection. Can you send me, please?
