After reading up a little on fungus, the pathogen settling from the air onto the planet's surface and the eventual formation of the fungi spores makes a lot more sense since the pathogen is "organic life" according to David in Prometheus, so what is essentially a type of bacteria becoming a fungus is accurate.
What I don't fully comprehend is the logic concerning where the spores are located. It makes sense that the spores would be especially present at sites that were heavily exposed to the pathogen, like right around the crashed juggernaut and in the surrounding vicinity, but by that train of thought, shouldn't the Engineer graveyard be absolutely covered with them since that was ground zero?
The Engineer corpses themselves should have been littered with spore pods.
Am I looking at this wrong or is this a legitimate plot hole?
