Gymnopus dryophilus (Bull.) Murrill is a common mushroom with very common features. It has a tannish-brown cap, white gills, reddish-brown stipe, and produces a white spore print. Honestly, kind of a boring mushroom.

However, in some instances, G. dryophilus hosts another fungus, Syzygospora mycetophila (Peck) Ginns & Sunhede. S. mycetophila is a jelly-like fungus that parasitizes G. dryophilus, so S. mycetophilatakes on the tannish-brown color of its host. S. mycetophila is capable of parasitizing the cap and stipe, but does not parasitize the gills.
