Re : Berkleasmium conglobatum (?)
I have seen a similar fungus on dead wood of Acacia in arid Australia, but the conidia were max. 30 µm long. I noticed in this species a strong ionomidotic reaction of the conidia in KOH (orange stain extruding in the medium). Did you test that?

Hi Ethan, I posted this species to our Facebook group in June and I just sent you a message with the link to that post. Here is a link to my post in Mycoportal:

I think your determination is correct. The conidia seem to darken in age to nearly opaque black. The farinaceous or flaky condition of the surface of the conidia is consistent with my observations. Also, you will see nearly black sporodochia in a collection and also these yellow-green sporodochia. These are younger sporodochia that have had the tops rubbed away and you see this yellow tissue (hyphae and conidiogenous cells) beneath. Best - Jason
