194 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
Colors of specimens were noted and recorded during the first 
years of my work by comparison with Saccardo’s ‘Chromo- 
taxia' in accordance with his descriptive terms. Recently I 
have been using Ridgway’s ‘Color Standards and Nomen- 
clature,’ 1912, which has a greater variety of colors useful in 
the characterization of the species of Thelephoracee. 
In my own work with collections of living fungi I am endeav- 
oring to gather for each species a spore collection on a glass 
slip. Тһе spores adhere well so that they may be covered by 
paper and preserved in the envelope with the dried specimens 
from which the spores were obtained. Such collections give 
the exact color and dimensions of mature spores. These dimen- 
sions are generally rather larger than those obtained from spores 
of sectional preparations of dried herbarium specimens. The 
spores of dried specimens, i. e., those remaining attached to the 
specimens, are probably too immature to be of normal size, and 
sometimes there are so few of them that one must exercise 
caution to avoid errors due to the study of spores foreign to the 
fungus. 
Latex exists in many species of several of the genera and is 
more abundant and conspicuous in some species than in others, 
and its containing elements often extend to the hymenial surface. 
When specimens are in the vegetative condition, injury to the 
hymenium may liberate the fluid contents of the latex bodies 
so that this fluid exudes in colored drops at the edges of the 
wound, or discolors the bruised surface. For many of our species 
there is a lack of data concerning the color of this fluid or 
the discoloration. Тһе latex bodies are pale brown іп micro- 
scopic preparations made by my methods and must not be con- 
fused with setze or cystidia. Latex is well shown in Stereum 
spadiceum, S. sanguinolentum, and Corticium lactescens. 
There has been a disposition on the part of some authors to 
regard the Thelephoracee as not sharply separated from the 
Hyphomycetes. ‘The specimens which I have collected, in striv- 
ing to find all the Thelephoracee of my collecting region, and the 
specimens received from my correspondents afford no embar- 
rassment in recognizing the most hypochnoid species of T'hele- 
phoracee by the База which characterize the families of 
Hymenomycetes in general.
