Split Gill Fungus

 

Schizophyllum commune - split gill fungus on a silage sack

 

Split gill fungus is a very distinctive mushroom. It has a Y-shaped gill cross-section and a frilly, scalloped cap with a fuzzy texture. It grows all over the world in tropical and temperate climates. It is often  found growing flat to the surface of rotting logs, but here it is emerging in dense clusters from the side of  a black plastic silage bag.
