Signs of a Healthy Sugarbush…

If you ever spot this curious little mushroom while walking your woods — take it as a good sign!

This is the Crown-tipped Coral Fungus (Artomyces pyxidatus). Its delicate, crown-like tips make it look like a miniature coral reef, right in the forest.

Why Does It Matter To Maple Producers?

  • It’s a Decomposer
    This natural recycling process – converting old wood into rich, fertile soil – helps sustain the health of maple trees and other plants.
  • It Unlocks Nutrients.
    By breaking down tough wood fibers, this fungus helps release otherwise locked-up nutrients (such as calcium, magnesium, and potassium) back into the ecosystem. These nutrients are essential for sugar maple health and productive maple syrup yields.
  • It is a Key Member of a Diverse Forest Ecosystem.
    The presence of this fungus contributes to greater biodiversity and a more resilient sugarbush. Fungal diversity is associated with healthier tree root microbiomes, which can improve disease resistance and growth outcomes for maples.

So next time you’re out in the sugarbush, keep an eye out for these hard-working corals. If you happen to spot them, you can smile knowing that they are a sign of a stable and healthy ecosystem.
