250 AGARICUS SURRECTUS, 
Agaricus Surrectus, 
another (agaricus caseus), which has a uniform foot- 
stalk, though not of common occurrence. Thus a plant, 
Stipes — solid, tapering upwards, rather thick immediately below 
the pileus, three inches high, thick as a reed, white, and often 
downy, wrapper at the base. 
Many of this species of singular plant I found in October, 1819, 
springing from a confluent mass of a. caseus. Bolton’s a. pulvinatus 
is something like our plant ; but he describes his under side as per- 
fectly flat, and represents a singularity in the termination of his la» 
minee, which is not observable in our a. surrectus.
