Festuca nutans, Phalaris arundinacea, Pou pratensis, and Spartina 
stricta. Cultures have been made of the ergots on the above-named 
grasses, and, although they have begun to grow, it is not yet possible 
to say whether they all belong to Claviceps purpurea. ‘The ergots on 
Festuca, Phalaris, and Poa, were all small and pointed. The form on 
Spartina was found in abundance along the Charles River, in Cam- 
bridge, during the month of October, and was exceedingly beautiful. 
In some cases, nearly all the flowers were affected; and there were as 
many as forty or fifty ergots on a stalk, all from one to two inches long 
and regularly recurved. 
ImperFrect Forms. — During the winter of 1876-77, we received 
specimens of onion bulbs, which were more or less injured by the smut, 
from Green’s Farms, Ct. On the outer scales of the bulbs, the smut 
was mixed with Aspergillus niger, Van Tieghem. The Aspergillus 
was identical with European specimens. Another small and delicate 
species of Aspergillus found on an excrescence on blackberry stems, 
answers tolerably well to the descriptions of A. niveus, Mich.; but 
its conidia are not produced on basal processes, which have several 
sterigmata, as is said to be the case in that species. We have found a 
Pestalozzia, which seems to be identical with P. truncatula, Fuckel, 
common on the cones of Norway spruce at Newton. We have received 
from Mr. W. C. Stevenson, Jr., the same fungus on spruce cones from 
Westchester Co., Pa., to which the name of P. Stevensonit has been 
given by Mr. Peck, in the “ Bulletin of the Torrey Club,” Vol. VI.

Nore. — We are indebted to Mr. M. C. Cooke for calling our attention to 
the fact that there is no description of Hendersonia Curtisii, Berk., H. nobilis, 
B. & C., nor H. pubens, B. & C. Of the first-named species, there is but one 
specimen in Herb. Curtis; “No. 2102, fol. mort. Narcissi? Society Hill, S. C.” 
The spores which we have examined are hyaline and undivided, and too young 
to allow one to say whether the species is a Hendersonia or not. There is a 
sketch, however, attached to the specimen, showing a spore with one septum 
and another with two. JH. nobilis, B. & C., is also represented by a single 
specimen; “‘ No. 5027, ad lign. denud. Cary, April, 1855, Society Hill, S. C.’’ 
The spores are oval, .009-.012 mm. by .02-.024 mm., dark colored, usually 
uniseptate, and usually but not always constricted at the septum. We have 
only in one or two instances seen two septa in the spores of this species, and do 
not understand why it should not be called a Diplodia. It must not be forgot- 
ten that there is a Hendersonia nobilis, Dur. & Mont. Flore d’ Algérie. 
With regard to Hendersonia pubens, B. & C., mentioned in Curtis’s “ List of 
North Carolina Plants,” the literature is very complicated. The specimen
