Bulbophyllum mystax and pyroglossum smell

[Bulbophilia]

Hi ORCHIDBOARD, I was wondering if anyone has seen flowers of bulbophyllum mystax or pyroglossum and if these plants have a foul scent. First photo is of pyroglossum second is of mystax

I have a mystax and the flower smells kinda fresh water fish. Not rotten fish, but like a freshly caught bass or trout. The smell is VERY faint and you have to stick your nose almost on it to smell it. Not sure about your other Bulb.
