a grayish-colored stroma, which afterwards developed in spots into 
dark-colored masses, in which finally perithecia were formed and asci 
containing very long and filiform spores. The fungus was described in 
“ Grevillea,’ March, 1876, under the name of Dothidea voraz, B. & C. 
Two forms are mentioned by Berkeley, to which the names of D. pilu- 
leformis and D. atramentaria were given. Our fungus corresponds 
to the former represented in Herb. Curtis by No. 1809, Santee Canal, 
S. C., collected by H. W. Ravenel. The same species was described 
by Peck, in the 27th Report of the “ Botanist of the State of New 
York,” p. 108, under the name of Hpichloe Hypoxylon. A question of 
priority may arise, because, although the Report was for the year 
1873, and bears the date of December, 1875, it was not given to the 
public until the latter part of 1876, if we are to consult the date at 
which it was sent to the publishers of the “Torrey Bulletin.” To go 
back of that date would be to open the question of manuscript names, 
which would result in the adoption of the name of Berkeley and Curtis, 
as the fungus was first examined and named by them in about 18954. 
As to whether the fungus should be called an Zpichloe or a Dothidea, 
we do not care to express a decided opinion. The genus pichloe 
depends for its existence more upon the peculiar habitat of the species 
included in it than upon any distinct anatomical characters. The 
present species if considered an Jpichloe, would seem, however, to 
weaken the claims of the genus to a position apart from Dothidea, in 
which Lpichloe typhina has been placed by some writers. We should 
be inclined to take what some would call a backward step, and call the 
fungus simply Spheria vorax. 
In the 28th Report of the “ Botanist of New York State,” bearing 
the date of 1876, Peck refers to Hpichloe typhina, found at Oneida by 
Warne, and says that he does not know that the plant has been before 
detected in this country. It was, however, found by Schweinitz on 
Muhlenbergia erecta, and mentioned by him in the “Syn. Fung. Car. 
Sup.,” No. 65, in 1822, and again by Curtis (1. c. p. 151). It was 
collected in South Carolina by Ravenel, and referred to by Berkeley 
in “ Grevillea,’ September, 1875, and it has recently been sent by 
Professor C. V. Riley from Missouri. 
The ergots or sclerotioid forms of different species of Olaviceps are 
common near Boston. Besides the form on rye, we have found it on
