Hello Martin
I consider myself as someone who is interested in Mycology and who takes photos as a record. I have friends who will take 30 minutes taking fantastic photos of relatively common species which I am often jealous of but I tend to take 5 minutes (2 minutes ;)) taking the photo and the extra 25 looking for more specimens. I do take on board what you say though and have just spent the last hour with Photoshop videos seeing how to improve the photos.
There are many excellent photos on here of different Scutellina but as you say they usually stop short of microscopic detail. Although a majority do look like S crinita/scutellata there are a significant minority which are definitely one of the many different species you have in the US.
I am not a professional mycologist so am not looking to publish any works on this or any other group but I would be interested in looking at any of your finds if the time and expense does not put you off.
You might try a provisional key I have developed here

Most of your spore shots have a blue background.

It does not affect what can be seen, but consider rinsing the specimen by applying a full water dropper to one side of the cover slip and a paper towel to the other. This will draw away stained liquid near the spores. You can also apply AWB to a .jpg in many programs (including Gimp and Lightroom) to assign the blue background to a neutral gray. Most of the posts on Scutellina do not include spore dimensions or hair length. Your posts do suggest to me that Scutellina in NA is more diverse that we give it credit for. Would you be interested in my collecting material for you?

I have two Nikon scopes an SMZ645 dissecting and a E400 Eclipse compound.
To stand any chance of identifying Scutellinia you need to use Lactophenol Cotton Blue. It has the same effect as Meltzers on Russula and Lactarius spores in that the stain is taken up by the ornamentation. With S legaliae the ornamentation is so big it is less important but in most of the others it is vital to use LCB.
