Wildlife Spotting

hi.i'm the third one, who suggest you: Genus: lepiota ( http://www.google.nl/search?hl=nl&cp=7&gs_id=s&xhr=t&q=lepiota&safe=off&gs_sm=&gs_upl=&bav=on.2,or.r_gc.r_pw.,cf.osb&biw=1264&bih=674&wrapid=tljp1325282785648012&um=1&ie=UTF-8&tbm=isch&source=og&sa=N&tab=wi&ei=5jX-Tp2TL4nZ8APcwqTOAQ ). When i read "diameter about 20 cm" i think, it could be "macrolepiota procera" ( http://www.google.nl/search?hl=nl&cp=13&gs_id=1e&xhr=t&q=macrolepiota+procera&safe=off&gs_sm=&gs_upl=&bav=on.2,or.r_gc.r_pw.,cf.osb&biw=1264&bih=674&wrapid=tljp1325282821179024&um=1&ie=UTF-8&tbm=isch&source=og&sa=N&tab=wi&ei=DDb-Toj4BMXf8gO2yqTMAQ ) ---> he is the biggest in the genus:lepiota/macrolepiota. good luck (very possible a lepiota species !!!)
