Similar to Helminthosphaeria?

Ascomata grew on the trunk of broken pine (Pinus sylvestris), on wood. Morphologically similar to Helminthosphaeria but I do not know this species so I am asking everyone for help in identification.
The size of the spores varies greatly, so I am giving only an example in the photo.

Re : Similar to Helminthosphaeria?
The ascospore germ slit suggests Coniochaeta. Helminthosphaeria ascospores have a germ pore.

Re : Similar to Helminthosphaeria?
Hi Andy
Thank you very much for specifying the type.
Looks like I have a serious problem again. The genre is completely unknown to me, but luckily some literature can be found.
So far I have looked at a few works and the only genre that has common features with my collection is Coniochaeta Tilakii.
- very similar sizes of spores
- a slit on one side of the spores
- spores in a gel shell
- perithecia densely covered with setae

However, I do not want to believe that this is this species?
A completely different substrate.
I suspect it will remain "sp" but I will try to explore more mature perithecia anyway.
Mysterious kind!

Hi, possibly Coniochaeta malacotricha ?

Re : Similar to Helminthosphaeria?
Thank you Peter
It is not enough to have a key, you have to be able to use it. The first species of its kind, so I missed something and missed that species.
The species you propose seems very likely and even found in Poland by Chlebicki, also on a pine tree.
The features are very compatible, but the description of the spores makes me wonder?
Is Chlebicki researching dead spores: "large refractive oil-drop"?
Thank you once again.
I check other features yet but I suspect that I determine it just as you suggest.
