Just based on the pictures, I think it is unlikely. I can't remember what you said it smelled like. Geotrichum can be *very* stinky, though. It can go through phases of shimeji mushrooms, and farty broccoli. It's not as strong as b. linens, which smells like gym socks, but my wife complains about it every time I take out my cheeses to flip :-) You would notice b. linens as well -- the pretty white geotrichum on those cheeses would be going orange/pink. It's not always easy to see at first, but it's not usually particularly bad smelling (from b. linens) before the point where it is obviously turning orange/pink.
