Like all other fungi, P. cubensis acquires its energy by feeding on and breaking down organic materials. This is accomplished when the fungus secretes exoenzymes onto the material. Once it's been digested, the fungus can ingest it and utilize it as needed. This characteristic is unique to the fungi kingdom. Unlike animals, who ingest then digest, fungal organisms perform these tasks in reverse order. This can be explained through evolutionary adaptations, which now allow fungi to consume a wider variety of materials.

Like animals, fungi also take in O2, while giving off CO2, as a byproduct. Plants, of course, do the opposite. P. cubensis then uses the O2 taken in to respire while it acquires its nutrients by absorbing the materials it has digested in the soil. The branching network, known as the mycelium, is made up of an endless amount of tiny hyphae that branch out and form a net.

Next is an explanation of how P. cubensis reproduces.
