I think I may have found the teleomorph of Dendros
Collected 24 december 2015, on Ulmus americanus bark in Ottawa ontario.
the Perithecia show stricking yellowish coloration.
The asci seem to be bitunicate, do not react in melzer and bear 8 spores, the spore measure 28-31u*10-12. The spores contain several (up to 9-10) horizontal septum and 1-2(3?) vertical septum.
Seem to be promising for T chrysogramma, however I can't find pictures to compare.
I have the specimens in case anyone is interested in them
Regards

here is a paper by Jaklitsch & Voglmayr which includes photos of T. chrysogramma as well as further literature on that species and a key to the genus: tps://www.researchgate.net/publication/270283146_Persistent_hamathecial_threads_in_the_Nectriaceae_Hypocreales_Thyronectria_revisited_and_re-instated
