What fungus produces a silvery sheen and black droplets ?

I am examining a presumed fungus that produce a silvery sheen under the epidermis and exudates some sort of tiny black droplet on the leaf surface. I have dissected small leaf segments (0.5-1.0 mm) and dropped them on some media perhaps I can cultivate the fungus. This was found on Ferula melitensis which is quite resistant to fungal phytopathens. I dont think it is a soot fungus , but I am all ears to suggestions!

Hii Stephen,
it's not easy to judge based on these macroscopic pictures, but it would be some powdery mildews where you can see the white anamorph and the dark chasmothecia.

Thank you Björn. I have dropped some small pieces on Sabourad and PDa and see what I get and report back. I was confused with the 'black droplets'

Re : What fungus produces a silvery sheen and black droplets ?
Well we have something workable (arrows) . I guess the mildew in question is the white fluffy colony. I will subculture from this mycelium and in the meantime check if there are some conidiophores/condia to lead to some identification. I am interested coz I seldom see this common endemic plant infected. Underlying is a dull green presence (Penicillium-ish)
