Are there any completely autotrophic species of fungus?

If so, what species are they? What ecosystem do they live in? Some answers from Quora state that a fungus can never be autotrophic, but why is that?

Thanks for your time!

  • $\begingroup$ There are some radiotrophic fungi in Chernobyl. Not sure if you would consider that as an example of autotrophy. $\endgroup$ – WYSIWYG May 24 '19 at 10:01

no none of the fungi in the nature is autotrophic. they are dependent mostly upon dead and decayed matter. the reason that they are not autotrophic is that they lack any type of photopigment to carry out photosynthesis. photopigments are necessary because the are the only components that can trap the solar energy and use it to extract the electrons from the inorganic source such as h2s or h2o by splitting them which are further used to prepare ATP and NADPHH+. these 2 are the assimilatory powers for the further dark reaction. so if these are not there then the processes of photosynthesis would not be there and therefore the organism will not be able to produce its own food in turn it would depend on other autotorphs for food (in case of fungi dead and decade matter).
