Hysterioid on Pinus bark

The fruitbodies aren't in the best condition and must've developed last season. But there were spores to be found and some asci as well.
The spores have one septum and measure 27.8 - 32.7 × 8.8 - 9.5 µm.
Actidium baccarinii is the best match I found, but it's spores shouldn't be nearly as big as these are. Maybe the large size is because of germination? Or is there some other alternative?

Re : Hysterioid on Pinus bark
Thanks a lot for the answers and links!
That seems to be the right direction -- so this actually belongs to Patellariaceae.
I found a description of Poetschia buellioides (A reassessment of the genera referred to the family Patellariaceae (Ascomycota)), but it mentioned that that one grows on deciduous wood; although there appear to be sightings of it in GBIF from Pinus. Otherwise it seems to fit pretty well.

Re : Hysterioid on Pinus bark
Ok, good to know! This species and even the genus seems to be missing from the Finnish species list. Probably once again one of these common but rarely-if-ever reported cases.

Re : Hysterioid on Pinus bark
I have made a key to hysterioids in Fennoscandia in case you are interested.

Ah yes! I actually downloaded that last week from researchgate:

A very nice key. Somehow I just managed to miss this one...
