Cypripedium pubescens and C. spectabile. (Vick’s Ill. Month. 
Mag., x., p. 217; colored plate.) 
Desiderata of the Herbarium of the Department of Agriculture A 
Jor North America, north of Mexico, Ranunculacee to Rosa- 
cee inclusive.—Geo. Vasey. (Dept. Agric., Bot. Division, 
Bull. No. 4, pamph., 8vo., pp. 15, Washington, 1887.) 
fungi—A List of Works on North American.—W. G. Farlow 
and William Trelease. (Bibliog. Contrib. Library of Harvard 
University, No. 25, pamph., pp. 36, Cambridge, 1887.) 
We are pleased to chronicle the completion of this great piece 
of work, the first part of which we noted a few months ago. 
About 645 titles are given, and the list is undoubtedly as com- 
plete as such lists can be made on the first attempt, for we have 
no doubt that these industrious authors will come across a few 
More articles every year for some time to come. Not the least 
interesting feature is the arrangement of births and deaths of 
authors cited, by which we are enabled to ascertain the age of 
everyone who has had anything to do with our Fungi. 
Fungi of Lllinois— Parasitic, IJ.—T. J. Burrill and F. S. Earle. 
(Bull. Ill. State Lab. Nat. Hist., ii., pp. 387-432.) 
The first paper of this series gave an account of the Illinois 
Uredinee ; the third and fourth will be devoted to the Perono- 
Sporee and Ustilaginee. The authors of the Erysiphee have 
Studied the group for many years, and Mr. Earle has given them 
his special attention in both field and laboratory. Two species 
and twelve hosts of other species were collected in the State by 
him alone. The description of the group is followed by an account 
of the development and notes on the classification. Very good 
figures illustrating the six genera accompany the key to the 
genera. The descriptive portion is followed by an index of spe- 
cies and of host plants. 
Twenty-eight species are described: Spherotheca, 5; Erysiphe, 
4; Uncinula,6; Phyllactinia,1; Podosphera,1; Microsphera, 
It. The nomenclature is in harmony with that adopted for the 
Uredinee, and conforms as far as may be to that of Winter in 
the Kryptogamen Flora. Spherotheca mors-uve (S.) B. & C., is 
kept separate from S. pannosa, to which it has been referred. 
The form on Agrimonia is referred to S. humili (DC.), Burrill.
