no means clearly defined and the Jamaica alga corresponds better with 
the forms of C. virescens than with any other species. How far the base 
of C. virescens may be changed by the substratum is not at present suf- 
ficiently known. In this connection may be mentioned No. 47 of C. L. 
Smith’s Central American Fungi which was issued under the name of 
Caemansiella nicaraguensis, Ell. & Ever., which is not a fungus, but a 
species of Cephaleuros. In the second century of the above named work, 
a new label for No. 47, was issued with the name changed to Cephaleuros 
virescens. It seems to me that it should be referred rather to C. cande- 
labrum Lageih. & Schm., which was later (Allg. Bot. Zeit. V 3, 1899) made 
by Schmidle the type of a new genus, Phylloplax. Possibly further study 
might show the form on guava, so far as its basal portion is concerned, 
is the structure of Phylloplax, but present available material is not in 
condition to determine that point. The sporangia of the guava form, 
Normener, are more like those of C. virescens than those of Phylloplag 
candelabrum, and lack the verticillate arrangement which seems to be char- 
acteristic of the latter when well developed.” (Signed by W. G. Farlow.)
