Agaricaceae 



Agaricus. or reddish hue on the freshly-exposed surface. This is a very distinctive 

 character and with the maritime habitat makes the species easy to rec- 

 ognize. Another species, Agaricus haemorrhoidarius Kalchb. exhibits 

 a similar change of color in its wounded flesh, but is of very rare occur- 

 rence with us, does not, so far as ascertained, grow near the sea, has a 

 darker cap and a long hollow stem. The stem in the maritime mush- 

 room is short and solid. Its collar is very slight and easily destroyed.
