Habitat/Hosts | Twenty-one genera of hardwoods. Most common on birch, but also infects poplar, alder, apple, ash, black walnut, buckthorn, cherry, hazel, ironwood, maple, mountain ash, and willow. |
||||||
Identification | The fruiting body (conk) is a 2″ to 8″ wide, ¾″ to 4¾″ thick polypore. It is hoof-shaped, rounded and curved downward on top, flat or slightly angled upward below. There is no stalk. The upper surface is brown and hairy when young, soon becoming gray and hairless. Older specimens are black and often cracked. The margin is brown and velvety on actively growing conks. The underside is light or dark brown. The pore tubes are distinctly layered (stratified), one layer developing each year. Older layers often become buried. The flesh is hard, woody, and dark brown or rusty brown. When cut in cross section there are white lines (mycelial threads) running through the flesh and older, buried tubes. An individual conk can survive for years, forming a new ridge or furrow each year. It is usually found on the trunk of a living tree. |

Similar Species |
Aspen Bracket (Phellinus tremulae) in Minnesota infects only quaking aspen and bigtooth aspen. It is the only hoof fungus found on aspen. True Tinder Polypore (Fomes fomentarius) older specimens are lighter and uncracked above. The margin and undersurface are whitish and velvety on actively growing conks. The pores are not stratified. The flesh in cross section does not show white mycelial threads. |

About
Uploaded on Sep 1, 2011 I explain the difference between true and false tinder fungus, and test my theory that false tinder fungus doesn't require prior preparation. I have been told in the past that false tinder fungus must be boiled with the ash of a plane tree or soaked in order to take a spark. I wanted to know if I could simply dry out false tinder fungus in the field and use it as is. |
