Growing in greatest quantity on filled land and rubbish 
piles beneath the Sixteenth Street viaduct. The horse 
manure which sifts through the flooring and blows over 
the side of that structure has greatly enriched the ground 
beneath, making the spot a favorable one for the growth 
of this and other fleshy fungi. Occuring also on lawns 
and vacant lots in the city.
