174 A CATALOGUE OF BEITISH POISONOUS FUNGI. 



pallid, soon rosy, numerous, unequal, broad beliind, free. Odour 

 sti'oug, not pleasant. Taste rather nauseous. Spores pink. 



Obs. Its principle is probably narcotico-acrid, but is not very virulent. Vol. 

 gloiocepbala is like this, but larger, taller, and iimbonate. It is said to contain 

 the same principle. Either might be mistaken for the Grisette, if the pink gills 

 and spores were not noted. — IF. D. H.
