Turkey Tail Report: Trametes versicolor Makes a Home in My Back Yard

I first saw my turkey tail patch growing in the early summer following a lot of spring rain on a stump we use for chopping firewood. I wasn't sure, as I'm a novice mycologist, but it had the markers: the ringed color patterns and the nested groupings of the caps. Also, the top side of the caps were fuzzy to the touch. I checked my trusty reference guide and it said to look for whitish spores. But I couldn't see any spores. Perhaps those emerging caps were too young to produce spores. (note to self: Ask an experienced mycologist when the caps typically start producing spores. My guess is there are a number of factors, like air temperature and humidity, in addition to the maturity of the mushrooming body.)

Turkey Tail emerging, July 11, 2016

I didn't think my turkey tail -- and yes, I call it MY turkey tail, for I have abounding, familial affection for my back patio patch -- would thrive in its volunteer location here in Bloomington, Indiana. During midsummer this spot was destined to get full sun for several hours a day, and the stump is too heavy to move without a good reason.

But, before I asked my 6'4" son to roll it back under the shade of the deck so the mushrooms wouldn't struggle in the heat, it rained. It rained a lot here--all summer l-o-n-g. While the western states fried, the midwest flooded and my turkey tail thrived. Here's my mushroom stump a month later.

This past weekend I photographed my turkey tail again, after a couple of weeks of "normal" late summer weather, in other words, HOT. The patch is clearly thriving despite the heat. I love the green rings and wonder why one section of caps has developed a new color scheme. When I shared my pictures with my Mycelium Running seminar tribe, one cautioned my identification, saying she had encountered a turkey tail look-alike.

Is MY turkey tail really Trametes versicolor, or an imposter? September 10, 2016
Under the cap you can see the whitish pore openings where the spores come out -- shot with a macro lens.

So I asked a local mycology prof, Dr. Michael R. Tansey of Indiana University, to verify or set me straight. From the two photos pictured above, this is what he said:
"This is Turkey-tail.  It is our most common mushroom.  It is very common.  I have been out walking today, and it is abundant.  FYI:  Most experienced mushroom people agree that what we call the Turkey-tail is, at the level of analysis of the DNA, many different species.  Indeed, I have seen unpublished DNA data from our local specimens, and they cannot be one "real" species.  I remember one of the most experienced wood-rot fungi experts, years ago, telling me that it must be a dozen species."  
Ta Da! I'm thrilled I correctly identified fungi--even if not DNA-specific in my ID--in the wilds of my back yard. And now that the sun has dropped lower and the stump is in the shade for more of the day, I doubt anything will disturb my turkey tail, until we have really cold weather. Remember, turkey tail is everywhere. See if you can find some in your neighborhood.
