This is good news. The idea of the delayed fungal evolution hypothesis was this:

"Before trees grew wood that was unable to rot and so became coal but after fungus came now wood is ruined and it's impossible to make coal again."

Understanding that coal formation is a reversible process and that a new agent didn't permanently ruin the process, is a sigh of relief.

So coal is actually renewable?
