I wouldn’t worry about the fungi from Yuggoth, John, or indeed beginning of The War of The Worlds. There’s widespread scientific skepticism that what happened was a meteorite at all.
“Statistically, it’s far more likely to have come from below than from above,” said Don Yeomans, head of the Near Earth Object Program at NASA’s Jet Propulsion Laboratory in Pasadena, California.
The noxious fumes that have supposedly sickened curious locals who went to examine the crater would seem to indicate hydrothermal activity, such as a local gas explosion, because “meteorites don’t give off odors,” Yeomans told SPACE.com.
The only evidence that it was a meteorite appears to be tiny fragments of dust, so best to reserve judgment at this time. False meteorite reports happen all the time. Of course, if the crater is a result of subterranean activity, that raises the possibility of the beginning of an invasion by the Mole Men.
