The Fungal Sample is a raw material that can be obtained from the Tree Mushroom in Mushroom Forests. The PDA description states that the sample contains fungal enzymes.


The player can obtain Fungal Samples by harvesting a "Mushroom Cap" with the Knife. The only practical use for Fungal Samples is fuel for the Bioreactor and for Hatching Enzymes.

Fungal Samples are not scannable.
