LickEA BIFORIS Mor, an.* Mr. Bilgram has favoured us with an 
example of this species gathered by him in Fairmount Park, Phila- 
delphia, Sept. 1908 ; there are about forty sporangia on a slip of 
bark, but they are so minute as hardly to be detected without the 
aid of a len ns; in our specimen they are glossy yellow-brown in 
colour and fusiform in shape, about 0-2 mm. long by 0:07 mm. 
end to end; when magnified 100 diam. they have a —o 
close resemblance to a date-stone. Mr. Morgan a the len

in striking contrast to the dull yellow colour of the plasmodium we 
have hitherto observed in this species. As ieatlas variation occurs 
in Trichia fallax and Dianema we essum; in both of these the plas- 
modium is either white or rose
