Fischer * in writing of Nidularia says that there are sixteen 
known species, but though De Toni + gives eighteen from all parts 
of the world, it is more than probable that several of these are 
either synonyms of other species or belong to other genera. 
Tulasne gives eleven species, to nine of which he adds “non 
vidimus’’! the remaining two being new species—MVidularia aus- 
tralis from Chili, South America, and Midularia Duriaeana from 
LaCalle, Algeria (Mauritania). From America several additional 
Species have been described, namely, Vidularia Alabamensis Atk. f 
from Alabama, which we have reduced to Granularia pulvinata, 
and Nidularia rubella FE, & E. § from New Jersey. This last 
species is very uncertain, in fact it may not belong to this family at 
all, as the sporangioles are quite different in texture from those of all 
the other species, and have never been found to contain any spores, 
being filled with small pieces of amorphous hyaline matter. It is 
hard to believe that the plants are in an immature condition as the 
Peridial walls have in some specimens almost entirely disappeared. 
The only remaining species of Nidularia which has been described 
in this country is Vidularia candida Peck which has been referred 
to the preceding genus. Two heretofore unpublished species of 
Granularia complete our present list: Gvranularia castanea, a 
herbarium species of Ellis & Everhart, under the name of idularia 
Castanea, from New Jersey found in 1883, and Granularia rudis 
Peck, from California.
