The veiled hypholoma is common in our lawns and yards. It is of a 

 dull white on top of pileus, very brittle, flesh thin, gills white at first, 

 then violet and lastly dark with the dark purple spores. The stem is 

 white and hollow. It is not poisonous. In young specimens the veil 

 hangs from the margin of the pileus ; hence the name.
