Pontiff's Skull cap

I wonder if people can help with me source this.

There is apparently only one space left for the pontiff skullcap, which is placed inside a glass case within the Vatican. It is said that John Paul I death was to bring forward the final laying of skull caps within the Vatican, as there was only two spaces available at the time.

The next pope would be unable to place his skull cap with those of his predecessors signalling he would be the last pope of the catholic world, he would be black and would show the way to the end of world as we know it.

Is this a merging of two prophecies or just confusion?
