subgenus of Lepiota, while Psathyrella disseminata and P. im- 
patiens are transferred to Coprinus, following the opinion of 
Quelet. Three new species, Lepiota Cortinariiis, Coprinus Han- 
senii, and Coprinus bisporus are described in this part. 
A separate from the report of the New York State Botanist 
for 1914 giving keys and descriptions of the species of Marasmius 
occurring in the state appeared in December, 1915. This paper 
was prepared by Professor L. H. Pennington, of Syracuse Uni- 
versity, whose work on the species of Marasmius occurring in 
temperate North America appeared in Volume 9, part 4, of 
North American Flora, issued in April, 1915. Dr. Pennington 
reported 71 species of this genus from temperate North America 
and his list of species from New York includes 61 species. This 
means that there are still many undescribed species in other states 
to be discovered and published. Species of Marasmius aid 
greatly in the formation of humus, and they very rarely cause 
plant disease. The common fairy ring fungus, Marasmius caryo- 
pliylleus, is a weak parasite of grasses, and this species is prac- 
tically the only one in the genus which is used for food. 
A very interesting and important list of the fungi of North 
Elba, New York, which contains many additions to Peck’s list of 
North Elba plants published in 1899, appeared in December, 1915, 
as a separate from the report of the state botanist for 1914. This 
list was prepared by Professor C. H. Kauffman, of the Univer- 
sity of Michigan, after three weeks’ collecting in the vicinity of 
Newman in September, 1914, assisted by Mr. E. B. Mains, who 
gave special attention to the rusts and ascomycetes. The region 
covered was small, but the season was unusually good. Two new 
species are published in this paper, Boletus rubritubifer Kauffm., 
found under spruce trees, and Cortinarius clirysolitus Kauffm., 
found in a sphagnum swamp under balsam trees. 
The chestnut canker is -reported in at least two localities in 
Nebraska, having been shipped there with nursery stock. The 
effect of the canker on chinquapin in Virginia is being observed
