This mushroom starts to come out in the late spring and can continue on through the fall. It is likely one of the largest mushrooms that you will see out in the spring time. It can grow directly from wood, but can also appear to be growing terrestrially on occasion from buried wood. Look for notched gills and the brown color to the cap. There are also commonly rhizomorphs attached to the base of the mushroom.

There is a second variety called M. rodmani form murina that has a gray cap and a shorter, stout stem. It is pictured below as well.


Clitocybula lacerata is smaller.
