I believe that is simply a vent for the blower bearings. Not so important as a vent but there will be a large, exposed hole in the blower motor housing. Dirt, crud and moisture will kill that blower motor very quickly if left open.
Mine crumbled away too when I was troubleshooting a blower problem. I tried to rig up something which sucked, quite frankly. When I had difficulty finding the right blower motor at the parts store, I decided to remove the one from a parts car I had. Strangely enough, it had an elbow that went into the blower "box" like a grommet rather than being a part of the rubber cover. This has been working well ever since the change.
To note, the piece that crumbled to dust was on my 93 SSEi and the part I replaced it with was off of a 93 SE with the SLE package.
