The Shaggy Parasol is closely related to Chlorophyllym molybdites, a poisonous look-a-like which appears in similar habitats - park lawns and along sidewalks. Eating this mushroom will likely cause gastrointestinal problems, which while not fatal, will be very unpleasant. The best way to differentiate Chlorophyllum molybdites from Chlorophyllum rachodes is to take a spore-print. The former has a green spore-print, while the latter’s spore-print is white. In fact, given sufficient time the gills of Chlorophyllum molybdites will also turn green. The other way to tell the difference between them is to see if your specimen bruises reddish before slowly turning brown. If it does, you have Chlorophylum rachodes. 023-001
