Mars Life? Fungi-like Growth

There appears to be are images that researchers claim is life on Mars. Images taken by NASA’s Opportunity and Curiosity rovers as well as the agency’s HiRISE high-resolution camera attached to the Mars Reconnaissance Orbiter look a lot like Fungi on Earth. Fungi can live in extreme radiation. The researchers cannot completely rule out minerals, weathering, and unknown geological forces that are unique to Mars and unknown and alien to Earth. However, if they saw this on Earth they would definitively call it Fungi. A lot of follow-up work will be done to confirm what could be a historic discovery.
Total conclusive proof will require a sample return mission or sending some ultra-specialized gear to Mars.
UPDATE –
It is likely a false claim. NASA did not have a press conference to announce it, the journal where it is published will publish almost anything.
