What in the Woods Is That?

Play our biweekly guessing game!

Whatever draws us into the forest—be it birdwatching or logging, hiking or hunting—all of us are unified by the sense of wonder we feel in the outdoors. The forests, fields, and streams of our region are full of mystery, and if you stop and look closely, you’ll see all sorts of oddities.

Below find a picture of one such woodlands curio. Guess what it is and you’ll be eligible to win a Northern Woodlands woodpecker magnet designed by artist Liz Wahid. A prize winner will be drawn at random from all the correct entries. The correct answer, and the winner’s name, will appear when the next column is posted and in our newsletter (sign up here!).

By the Mark

What caused the orange mark on this Ostrya virginiana tree (known by many common names, including hophornbeam, hardhack, and ironwood). It looks like a poor boundary blaze, but it’s not.

Answer

It’s yeast fungus Cryptococcus macerans growing on sap that’s oozing from wounds created by a yellow-bellied sapsucker. Although the yeast is reported to grow on other species of trees, it appears to be most common on members of the birch family in the Northeast.
