A slime mold that doesn't look like much, but is pretty when viewed closely.
I believe this is the plasmodium stage of Wolf's Milk Slime.
According to Michael Kuo, A. muscaria var. formosa is actually a European species, while the North American species is A. muscaria var. guessowii. http://www.mushroomexpert.com/amanita_muscaria_guessowii.html
This cup fungus is very small, but I was already on the ground taking another photo when it caught my eye. The second photo shows what it looks like from one's knees.
This fungus grows on well-rotted wood. It turns black as the spores mature.
I'm unsure what kind of fungus this is, although I believe it to be a puffball. The pink colored fungus oozed out gooey pink and the dark brown fungus ejected a cloud of dark brown spores when poked.
