Just before leaving for a three-week vacation, I took some photos of a fungus covering a fallen dead hardwood tree. While I was in California, I watched a video by a charismatic fungal enthusiastic, Adam Haritan, who made it clear that my fungus was either Turkey Tail or a Turkey Tail look-alike and that the only way to know for sure would be to examine its underside.
If the underside was white and had tiny pores, my fungus was trametes versicolor, commonly known as “Turkey Tail.” If it was more beige and smooth, it was stereum ostrea with the pitiable moniker “False Turkey Tail.” If it was slightly purple and had a toothy structure, it was trichaptum biforme – “Violet Toothed Polypore.”
During the three weeks, I realized two things: 1) that I was subconsciously rooting for my fungus to be what mycologists call true Turkey Tail and 2) how prejudiced I was being. After all, “False Turkey Tail” was so-named only because of its resemblance to the topside of trametes versicolor, not because it had some nefarious motives as an imposter. And besides, Turkey Tail itself was named because of its resemblance to an actual turkey’s tail. And the poor Violet Toothed Polypore, which is in fact the most common of the three species, had the role of a third child, mentioned for its relationship to the other two.
When I arrived home, I headed to the log in question, picked off a piece of the overlapping fungus and flipped it over. It was clearly violet and toothy. As I celebrated the identification of Violet Toothed Polypore, I felt a tinge of disappoinment in myself for feeling a tinge of disappointment that it was not true Turkey Tail.
