Mars does indeed have liquid water, and a chance at more of it: https://english.elpais.com/science-tech/2024-01-18/massive-deposits-of-water-ice-discovered-on-the-equator-of-mars.html https://english.elpais.com/science-tech/2024-01-18/massive-d... : In 2018, Mars Express located a large lake of liquid water under the Martian polar ice. https://web.archive.org/web/20210902121223/https://earthsky.org/space/mars-ice-is-dusty-and-could-melt-study-says/ https://web.archive.org/web/20210902121223/https://earthsky.... : There is a chance that this dusty and dark ice might melt a few centimeters down. And any subsurface liquid water produced from melting will be protected from evaporating in Mars’ wispy atmosphere by the overlying blanket of ice. Is it likely that Fungi would end up in the right places on Mars, and even then grow in these conditions? Probably not. But worth investigating given what is known of psychrophilic fungi. https://link.springer.com/article/10.1007/s11157-016-9395-9 https://link.springer.com/article/10.1007/s11157-016-9395-9 : Fungi are able to grow and survive at low temperature and exist widely in polar and non-polar habitats. These cold regions are known for very low temperature, high ultra violet-B radiation, frequent freeze and thaw cycles and low water and nutrient availability.
