Key to Gilled Fungi

Note: Certain poroid fungi (e.g., Lenzites betulina, Gloeophyllum sepiarium) have pores which "break down" and
form gill-like structures. Unlike the true gilled fungi, the "gills" of these poroid fungi have a tough texture and are not
readily separable from the rest of the fungus. Certain other poroid fungi (Poroid Key Group B) also develop a
gill-like fertile surface.
