Pine Green/Gray Fungus: Lichens, Not Disease

Green/gray dried "fungus" on pine branches dying bottom-up = lichens on naturally shaded lower limbs. Not a disease.

Why It's Normal

  • Lower limbs die from shade (self-pruning).
  • Lichens colonize dead/dying bark—harmless.
  • Indicate clean air.

Action

  • No spray needed.
  • If concerned: OR Dept of Forestry free forester visit.

Key

Dead lower branches + lichens = healthy forest process. Your pine is fine.
