What it is

Stereum rameale is a plant pathogen infecting peach trees. It is often found in tiers on the dead wood of broadleaf trees.

Where and when to find it

Habitat
Commonly found on dead hardwood trees and branches across much of the eastern and central United States.
How to find it
Look on downed logs, stumps, and dead branches in deciduous forests. They often grow in large groups.

Worth knowing

  • It is a type of crust fungus, not a mushroom with gills.
  • It plays an important role in decomposition.
  • The 'crowded' part of its name comes from how it often grows in overlapping clusters.
  • It feels tough and leathery.
  • It helps make homes for many tiny forest creatures.
  • The underside is smooth, unlike most gilled mushrooms.

Why it matters

Crowded parchment helps break down dead wood, returning nutrients to the forest floor. This natural recycling keeps the forest healthy.
