Django I agree. No conidia of any kind. My bad.

Hyphodiscus is a genus of cup fungi

I don’t see cups here at all so I was confused why that was the identification on this application. I would say that the white is probably a secondary fungus here. Some sort of hyphomycete. I don’t see the crystals in your micrographs and the only structures that can be clearly observed are basidia. I am doubtful that any of the structures shown are conidiophores. Some could be cystidia, but I don’t see them clearly enough to be certain.

It’s hard to follow what you are saying

First I don’t see any cups unless you are referring to the white patches that I suppose could be cups. But consistency is missing. There are two colors, both yellow and white, on some crystalline mat. Are the two colors an indication of two fungi? You don’t mention the presence of the crystals, which seem unusually prominent. These patches are very common here, as you may notice on other observations I have made. I am not sure what this is, but it seems that it is not a great mystery to people who study corticiaceae.

…and in those cups, clear asci and ascospores

Django, I appreciate your comment and agree about the microscopy

What feature are you looking for to confirm Hyphodiscus?

Maybe Mycoacia uda or something similar

The microscopy here isn’t really clear enough to tell what beyond that this has 4-sterigmate basidia. It seems like there is likely a secondary fungus on this but I see no reason to think it’s a Hyphodiscus
