Seaver: Some Tropical Cup-Fungi 
187 
These studies are based on material in the herbarium of the 
Garden including numerous specimens obtained by Garden collec- 
tors in the West Indies and Mexico. The collections in several 
cases are accompanied by colored sketches made in the field by 
Mrs. Norman Taylor. These sketches show the colors to be a 
much brighter red than is shown in the published illustrations of 
the various species which must have been made from dried mate- 
rial or by guess from the descriptions. The photographs are 
made from dried material which in some cases is partially revived 
by wetting. On account of the tough consistence of the plants of 
these two genera they do not shrink a great deal in drying and the 
photographs compare very favorably with the drawings made 
from fresh material so far as the form of the cups is concerned. 
While these photographs do not bring out the colors they show 
many details which it is impossible to show even in a colored 
sketch. Drawings are made with the aid of a camera lucida, all 
spores being drawn to a common scale.
