Marasmius rotula
Common Name: Pinwheel Mushroom
Synonyms: Horse Hair Fungus, Species Fungorum
Substrate: Ground Debris
Location: Hardwood Forests
Spore Color: White
Gill Color: White or Whitish
Comments:
A fairly common mushroom that likes to fruit in abundance. It should have a thin blackish stem and a cap with deep pleats that forms a pinwheel pattern. Fruits from downed woody debris.
Lookalikes:
Some authors make the distinction of Marasmius capillaris, which grows on oak leaves, while M. rotula grows from wood. M. rotula also has a flat area on the top of the cap when viewed from the side, while M. caplillaris is more rounded. Marasmius felix grows specifically on Sycamore leaves.
