White cap covered with scales. The gills beneath the cap are white, then pink, then turn black and secrete a black liquid filled with spores. An excellent edible mushroom when collected very young (see pic. 2).
Very common in Central Europe and most parts of the northern hemisphere. Can be found from April - November on lawns, along gravel roads and waste areas. It is also very common in urban areas on fertilized lawns and park areas.
Interestingly this mushroom is carnivorous, it traps and digests nematodes (nematophagous). http://en.wikipedia.org/wiki/Nematophago...
