Re : Nectria sp. overgrowing Kretzchmaria
Hi,
This is a Cosmospora species. This species belongs in a species complex (Cosmospora viliuscula species complex). Species in this complex are notorious for occurring on Xylariaceous fungi. I am currently working on a paper for this group. I can tell you in advance that it might be necessary to identify the Kretzschamaria species to key the Cosmospora to species rank.

Re : Nectria sp. overgrowing Kretzchmaria
This is probably a true Cosmospora viliuscula given the host. Cosmospora vilior is a name in the old literature that was used for this species complex. Hower, it was incorrectly applied because the type species of C. vilior occurs on an Eutypella species.
