It is the middle of June in Northern Wisconsin, and we see Oyster Mushrooms popping up everywhere!  They grow with one flat side attached to the tree trunks of dead wood.  Sometimes you have to look high.  A lot of the times they lack the traditional mushroom stem, and have gills underneath the cap.  Their smell resembles anise, and it is one of the main clues.  Mushrooms are whitish yellow in color and can grow quite large, so just watch out for competitors inside, insects love to eat them too!

The Greek name is Pleurotus ostreatus meaning “sideways ear”.  They refer to seafood oysters based on their appearance and color, not the taste.
