Pinthanatos woodifungerius
Evolved from F. khthonspongos due to intraspecific competition and started to adapt for decomposition of Ultraplortatus and Megaplortatus wood by synthesis and release of acids allowing them to decompose the wood.
Found in zone D, masses of F. woodifungerius zoospores travel through the water table in search of Ultraplortatus and Megaplortatus corpses. Using its cell chitinous wall it does not need to deal with osmotic pressure. They can only move as far as the water table allows them to so they can only search for corpses during rain storms. Once they reach dead wood they will transition to their next life stage and start generating mycelia. The decompose the cellulose and lignin of the wood.
If environmental condition are too dry, fully matured cells will produce as many zoospores as possible before going into stasis. Zoospores during drawn out periods of dryness will also go into stasis. They continue to produce similar levels of fuscimalase as their ancestor.
