had issued five fascicles of fifty numbers each, and had others in : 
preparation, when his death, which occurred Sept..7th of this 
year, after a painful illness, has, it is to be feared, put an.end to 
this important undertaking. 
The parts of the world chiefly represented in the fascicles 
already issued, are: Europe, Southern Africa, North America, 
New Holland and New Zealand. This country is represented by 
twenty-eight species. Two of them, Calicium faculatum and 
Lecidea (Biatora) holopolia, are unedited species of Tuckerman 
from the Pacific coast. Two others, Umbtlicaria corrugata, Nyl., 
from Newfoundland, and Verrucaria (Pyrenula) aspistea, Ach., 
from New Jersey, have not been previously published as belonging 
to this country. No. 17, Lecanora miculata, Ach., described by 
Tuckerman in his synopsis, is not present. But, after the publi- 
cation of his synopsis, Prof. Tuckerman expressed the opinion 
that it was only Z. subfusca. A considerable number of other 
North American species had been sent to Prof. Lojka, and would 
have been issued in the fascicles for this year, which it is to be 
hoped, were in a state of sufficient forwardness to be distributed. 
The classification and nomenclature of this collection is that 
of Nylander, and it will require some knowledge of lichen sys- 
tems to place many of the species in the genera adopted by 
Tuckerman. Two of the finest and rarest species are Endocarpon 
(Dermatiscum) Thunbergii, and Parmelia (Omphalodium) Hot- 
tentum, from the Cape of Good Hope, which those who have 
the good fortune to possess the collection, can compare with the 
single American species of these genera. Prof. Lojka does not 
_ seem to have known Nylander’s genus Dermatiscum, but the 
apothecia of the specimens of D. 7 hunbergii are distinctly 
Lecanorine in his specimens. The name Cladonia lacunosa ought 
not to have been given for C. Boryi, Tuck., the name under 
which the species was first described and published, the other 
having been merely a herbarium designation. 
No. 186 is given as Graphis angustata, Eschw., a Brazilian 
lichen, the spore character of which, so far as I know, has not 
been investigated, and which is therefore, like most of the species 
of the older botanists, especially the tropical ones, uncertain. It is 
very unlikely that a distinctively Brazilian Graphis should occur
