The first microscope photo is from one of the brown spots that are on the regular photo. 2nd and 3rd scope photo are also from those brown spots but are more typical. The ones below that are from the normal surface area that does not have those brown spots, there we see the spores and ascus.

I wonder if those “hairs” are not from something else, the spores look typical of Chorioactis, I wonder what are the first one tough

note on the first micrograph the peanut shaped (spores?)

I emailed you the spore photos and photos of those dark colored raised bumps. The dark bumps look like areas with large numbers hairs with the scope.

Great beginning for 2013!

on the left part of the star you can see black dot inside the fungus, highly proposing something fungal

If needed I would be happy to put it under my scope and see if I can tell if it is a parasite and if its a fungal one, and if it has any spores, to take spore photos of the possible parasite and email send them to you if there are any.
I have never heard of a parasite of Chorioactis but with such a rare fungi there may not be any reports.

A parasite growing on chorioactis might be undescribed , if I where you I would keep the specimen and dry them, and maybe someone would want them?

Had the resources I would, as I, too was wondering what that might be….oh well..

you might want to check what is growing on it, if choriactis is the host of it, then it must be another rarity!
