SHORT NOTES. 
Fossomsronia cristata Lindb.—Although there are few records 
for this hepatic in Britain, it will probably be found to be widely 
distributed. It is most generally confused with F’. pusilla feck 
species. I also have it from Staffordshire (Rev. H. P. Reader) a 
North-east Yorkshire (Mr. Wm. Ingham). This species can fre- 
quently be known at sight from /. pusilla by its smaller size and 
capitate terminal leaves; but examination of the spores, whic 
e ca 
in mind that the two species are occasionally to be found growing 
together, as they have the same habitat—bare damp soil on foot- 
paths, sides of ditches, and fallow fields; thus each gathering 
must be minutely examined to avoid a mixture. The most frequent 
power not being used. Under a low power the spores of the various 
species appear much like otis plane As the literature of our species 
is scattered, I add a key which may be of service until descriptions 
are given in Mr. Pearson’s Hepatice of the British Isles:—

spcalaiieite of this plant from one of two patches observed on the 
bank of the Thames between Wallingford and Cholsey on vag 21st. 
It appears to be new to the county. —Ricuarp F, Towxp
