Dear friends
Among the old samples, which are stored in our mycological collection, I found one that was signed as Nectria decora. It is not N. decora a 100% and even non Nectriaceae representative, because presence of many threadlike, branched, septate paraphyses (pseudoparaphyses) in hamathecium.

Perithecia (pseudothecia) erupt in dense groups from the bark of thin dry twigs of Caranana arorescens. Externally perithecia looks olive-brown, but in a cross section the wall is clearly red-brown. The walls of fruiting are very thick. Asci are 67,3-83,6 x 14,2-15,8. Ascospores are arranged in two rows or obliquely, in some cases biseriate in the upper part and uniseriate below. Ascospores hyaline, muriform (with 7-8 transverse and multiple longitudinal and oblique septae), slightly constricted near the central septum, 16,3-21,5 x 4,7-7,6.

Alone I can not reidentify this sample.
If you have some ideas about it, I would greatly appreciate for your help.
