On macro characters alone that's similar to what I recognise as A retiruga........... ;)

Thanks Ken. I'm not sure though now as I think it might be the rarer A.spathulata as it is on a acrocarp and not a pleurocarp.

As well as the bryoparasitic ascomycetes mentioned above, obvious basidio's would be:
* members of the genus Galerina (difficult without specialist literature - the popular books generally feature on a handful of those which occur in this country); people on this site could help - you need details of spore ornamentation (oil!) and of the cystidia on gill edge and stem (handle carefully or these may disappear); also some are two-spored.
* members of the genus Rickenella - with experience these can be done in the field
* then there are odd members of genera like Hypholoma, Tephrocybe etc which have a moss-inhabiting lifestyle.

Moss ID to species is no problem for me, I've been doing bryology much longer than mycology. . . . .
In that case definitely have a go at the asco's - if you get decent pic's /measurements of spore ornamentation and know the host there are plenty of people on who are very knowledgeable about them and always willing to help. Keep an eye on Orthotrichum affine - look for unhealthy-looking areas and then have a bit of a 'delve' as the fungus occurs on the rhizoids - and you could get the 3rd British record (first in Sussex, this in Yorkshire, so it's presumably all over the place even though only described in 2006!) of Octospora affinis:
