This seems to be a very interesting specimen. I don't believe this will be a Beauveria species, because Beauveria has single-celled spores and your specimen clearly shows 1-septated spores. Unfortunately I could not determine the conidiogenous pattern through your photos.
Using the Humber's key for entomopathogenic fungi (I attached it for you) I reached a dead end on step 15. In fact, I was unable to find a suitable genus even in "The Genera of Hyphomycetes" book.

Could you try to make additional photos showing the conidiophore (or conidiogenous cell) with the conidia attached.

Sorry not help you so much.
