390 General Notes, [ May, 
a valuable paper on “ The various forms of Trichomes of Echin- 
ocystis lobata,’ in the March Botanical Gazette. It is accom- 
panied by a plate with nine figures. In the March Torrey Bulle- 
tin, J. B. Ellis hazards the belief that Coleosporium of Solidago 
(Uredo Solidaginis Schw.) is the rudimentary stage of the 
Dothidea (Spheria Solidaginis Schw.) common somewhat later 
in the season on the same leaves. In the same number a transla- 
tion appears of Dr. Herpell’s method of preparing the fleshy fungi 
for the herbarium. The essential features of the process are these: 
Stout sheets of paper are coated over with gelatine. The fungus 
is cut into thin longitudinal sections and these are laid upon a 
moistened sheet and afterwards placed in an ordinary press. 
uch preparations are said to retain their colors excellently.
