Birch Mazegill

Trametes betulina


Large clump of fungus with intricate gills that brown with age. T. betulina is also known as the gilled polypore and multicolor gill polypore. Cap is green (photos 4,5 show it covered with alga) and gray with orange at the edges.


Saprobic - grows on rotting logs on the forest floor. Seen in North Mount Loretto State Forest.


Shot 4 shows the fruiting body of another species of fungus on the log (much smaller and white), possibly the split gill fungus, Schizophyllum commune?

Thanks so much, Neil! The gills were soft, unlike the tough but flexible cap. Happy to share and I’m glad you liked this gilled polypore.

This is a really interesting spotting, Mauna. Great notes too. A gilled polypore? Where the gills soft, or woody like the top of the bracket. Definitely a fave. Thanks for sharing.
