This one is definitely Bulb. grandiflorum ... the variety or form is "aureum", meaning yellow (where the typical form has parts that are reddish-brown). So it isn't Bulb aureum at all. Bulb. grandiflorum is also known as Bulb burfordiense but grandiflorum is the currently accepted name. Yup, it's one of the stinky ones. But huge, beautiful flower. Not a hybrid, it's the species. The cultivar wasn't awarded, so the cultivar name 'Shining Fuji' doesn't have official standing, the grower clearly thought that it was good enough to recognize with a cultivar name.
It does like warm and wet.
You might want to sit back with a cup of coffee or hot chocolate, and listen to this talk by Bill Thoms that was Zoomed for a San Francisco Orchid Society meeting a couple of years ago (one the most knowledgeable experts on the genus in the US) . the full video is long, but it includes the rest of the San Francisco Orchid Society meeting, you can skip or fast-forward through the parts you're not interested in. But there's some good info. (I had to "brute force" the link to get it to show up at all, but if you click on it you'll get it)
