Lycoperdon perlatum
Puffball fungi
Habitat and Substrate: Grows in groups on soil, either little groups or big ones.
Description: Starts out little and looks quite spiny, then it gets bigger and the spines wear away and it gets a little hole in the middle where the spores come out in a puff. Average diameter is 2-3cm but can get bigger. These ones can pretty much be found most of the year.
