Hoof fungus,Tinder fungus

Whoa cool! thanks for telling!

I just read this on wikipedia if you're interested!

Fomes fomentarius can easily be confused with Phellinus igniarius, species from the genus Ganoderma and Fomitopsis pinicola. An easy way to differentiate F. fomentarius is by adding a drop of potassium hydroxide onto a small piece of the fruit body from the upper surface. The solution will turn a dark blood red if the specimen is F. fomentarius, due to the presence of the chemical fomentariol.

thanks

I'm just subbing to the comments
