Many bracket fungi form roughly semicircular shelves called “conks” on dead or living trees. I believe the pictured specimens are red-belted (or banded) polypore, though I am by no means an authority on shelf fungi. The red-belted bracket fungi, Fomitopsis pinicola, are one of the most widely distributed varieties of shelf fungi in North America, although they are rare in south-east USA. They are also one of the most prominent wood decayers in the coniferous forests where they reside. As shown in most of the photos, they excrete droplets of clear liquid from pores on the sides and bottom of the fruiting body. I was not able to find any further information on this fluid other than it being referred to as “metabolic exudate.”
These bracket fungi were discovered on a fallen log, while on a camping trip in the Okanogan-Wenatchee National Forest. The previous four blog posts include other discoveries in this same area. In fact, the dog vomit slime mold featured in one of those articles was only 50 feet from these shelf fungi.
Shortly after posting this piece, I came across another posting within the WordPress community by the ENVB 222 Bracket Fungus Group, entitled Bracket Fungi. This article contains a more in depth look into shelf fungi, including some interesting findings related to the red-banded bracket fungi.
