ing note on the Flora of Mammoth Cave, Kentucky. The species ob- 
served are all fungi, as follows, viz.: Coprinus micaceus, Fomes ap- 
planatus, Rhizomorpha molinaris, Microascus longirostris, Zasmidium 
cellare, Mucor mucedo, Gymnoascus setosus, Sporotrichum flavissimum, 
Laboulbenia subterranea, Coemansia sp., Papulospora sp., Bouderia sp. 
and Peziza sp. 
The Annual Report of the State Botanist of the State of New York, 
for 1894, just issued, is of more than usual interest, since it contains a 
comprehensive paper on the “Edible and Poisonous Fungi of New 
York,” illustrated by 43 colored plates. Included in the report is a 
paper by Dr. E. C. Howe on the “ New York Species of Carex,” in 
which one hundred and thirty-three species are described at length. 
The Report of the Botanical Department of the New Jersey Experi- 
ment Station for the year 1896 indicates that Dr. Halsted has been 
very industrious in his studies of fungicides. The many half-tone re- 
productions of photographs add much to its value. 
Mr. F. L. Stevens has reprinted from the Journal of the Columbus 
(Ohio) Horticultural Society (Vol. XI, No. 4) a convenient reference 
index to Dr. Halsted’s bulletins and reports on plant diseases. It will 
be very serviceable to botanists and horticulturists. The same writer 
published, in the journal cited, an account of the parasitic fungi on 
Ohio Weeds. Some of these have proved very destructive to their 
hosts. | 
Ascherson’s “Synopsis des Mitteleuropiiischen Flora,” of- which 
parts 1 and 2 have been received, promises to be interesting and use- 
ful, but its use will be greatly lessened by the failure of the author to 
properly indicate the authority for each species. The sequence of 
families in these parts is as follows, viz.: Hymenophyllaceae, Polypodi- 
aceae, Osmundaceae, Ophiogl , Salvini , Marsili , Equise- 
taceae, Lycopodiaceae, Selaginaceae. 
Recent Changes in the Nomenclature of North Ameri- 
can Trees.—In looking over the pages of Sudworth’s “ Nomencla- 
ture of the Arborescent Flora of the United States,” the writer noted 
the following changes which are not yet generally found in manuals 
and lists of species, and which it may be well to reprint here for the 
benefit of those who do not have access to the most recent literature. 
It is not thought necessary to repeat the list of hickories (Hicoria spp. 
formerly Carya spp.), since the changes in nomenclature which they 
have undergone are now well-known to every tyro. Nor is it neces- 
sary to repeat Torylon (Maclura), since it is eighty years since this
