No, NASA photos are not evidence of fungus growing on Mars, sorry - CNET

Despite what you might have read, the claims about life on Mars are shoddy and unscientific.

"Claiming that mushrooms are sprouting all over Mars is an extraordinary claim that requires better evidence than an analysis of photographic morphology by a known crank who has claimed, on the basis of the same kind of analysis, that he has seen fields of skulls on Mars," says Paul Myers, a developmental biologist at the University of Minnesota, Morris, who has followed Joseph's work in the past.
