Nectria?

This fungus was growing on an old decayed polypore, most likely a Stereum sp., in Pennsylvania, USA. It was covered in orange/yelllow synnemata, but also had some perithecia.  I was thinking that the synnema were maybe Gliocladium and the perithecia were Nectria/Bionectria etc.

I was referring to: "Three Species of Hypomyces Growing on Basidiomata of Stereaceae", by Kadri Põldmaa, Mycologia Vol. 95, No. 5 (Sep. - Oct., 2003), pp. 921-933.  But ascospores do not have warts.  After reading this I am leaning back to Nectriaceae.

There are some other options such as Sphaerostilbella, but I am not familiar with any of these. Do you think the synnemata and the perithecia are related, and that this a species of Nectria?
Thanks,
Devin

Re : Nectria?
Hola Guy, sobre Stereum y con estas esporas solo se me ocurre la Nectriopsis oropensoides, aunque no lo tengo del todo claro.
Saludos cordiales

Re : Nectria?
Hi Josep,
Nectriopsis is possible, but macroscopically it does look a bit different.  I think the perithecia are covered in some kind of hyphomycete ( or the real anamorph), without a subiculum that I see from photos of Nectriopsis. I will look into it though, thanks for the suggestion.

Re : Nectria?
For the moment, I believe the synnemata are Gliocladium, described as a anamorph of Sphaerostilbella.  I am refering to "Genera in Bionectriaceae, Hypocreaceae, and Nectriaceae (Hypocreales) proposed for acceptance or rejection". IMA Fungus. 2013 Jul; 4(1): 41–51, which declares Gliocladium as the anamorph for Sphaerostilbella.

Looking at some pictures from:
"Sphaerostilbella broomeana-group (Hypocreales, Ascomycota)", Kadri Põldmaa, Gerald Bills, David P. Lewis, Heidi Tamm. February 2019, Volume 18, Issue 1–2, pp 77–89. It looks like the anamorph is covering the perithecia.  

If the anamorph is covering the perithecium, how is the Gliocladium synnemata related? Does anyone know?
Thanks,
Devin
