Do you have a citation for this understanding? I hadn't heard this before so I did a brief search and found [0], but this seems to apply just to coal which goes through a lignite phase during its formation [1]. I'm not familiar the details of how other fossil fuels are formed, but I was under the impression it usually happens under the seafloor, are the same mechanisms at play in an undersea environment? It seems like fungi are more common on land than at sea [2].
