Outer wall

Known as the peridium, it is thick, tough, and coarse. It does not change color to red or black but tends to crack as it ages.

External fibers

The surface is covered in fine, tawny or pale brown mycelial strands that attach the body to the substrate.

Interior

The internal gleba transitions from pale yellow to olive-brown at maturity and contains small, irregularly shaped cavities.

Edibility

The fruit body of this species has a tough outer wall and an unpleasant, indefinite smell, though the taste is mild. It is considered not edible.

Nutrient Source

It forms a symbiotic relationship with trees, extending the tree's root system to help it absorb water and nutrients from the soil. In return, the fungus receives sugars produced by the tree through photosynthesis.
