March 10th. On a hillside above a small creek at Oconee Heritage Park, I found a hardwood tree with…
These brackets were similar in size to Turkey Tail (Trametes versicolor) brackets and had faded to be almost uniformly white.
The undersides of these brackets were dark with age, and had a maze-like appearance but lacking the radial orientation that I’d seen on the Trametes villosa brackets. These brackets were Trichaptum biforme, the Violet-toothed Polypore, yet another Turkey Tail look-alike.
It was a little surprising to find the maze pores still intact. Frequently, the pores of T. biforme break down into…
tooth-like structures. It’s not unusual to find them like this.
If you’re lucky, you might find young Violet-toothed Polypores. I found these last December at Fort Yargo State Park.
The caps were brown with distinctly purple margins.
Their undersides were also a rich purple, from which they get their common name, Violet-toothed Polypore.
Their pores have a zig-zag appearance.
As they age, the purple margin fades from the caps, and the…
pores lose their purple color.
The key to field identification of Trichaptum biforme, and differentiation from Trametes versiolor, is the characteristic pore surface. Even better, if you find young specimens with the distinctive violet coloration.
