1891, by Dr. R. C. Manning, Jr., who brought plants to the late Sereno 
Watson. These specimens are now preserved in the Gray Herbarium 
and, so far as the writer is informed, represent the only known station 
for the species in New Hampshire.

Tue eight species discussed in the present paper include five distinct 
additions to the New England flora. ‘The three remaining species 
have already been noted from New England, but their records have 
been either uncertain or incomplete. ‘lhe North American species of 
Cephaloziella, two of which are mentioned below, are in need of 
further study, and it is probable that other members of this genus will 
eventually be detected in New England. It is difficult, however, 
to treat them fully at the present time because most of them occur 
also in Europe, and European writers still disagree about their limits 
and relationships.

Lindberg’s Monographia Metzgeriae in 1877. The earlier writers 
accepted it in a broad sense and referred to it all the northern forms of 
the genus which were distinguished from M. pubescens by being 
destitute of cilia on the antical surface of the thallus. According to 
Lindberg the old M. furcata, as thus understood, was an aggregate and
