While examining specimens of other apple leaf-spot fungi in 

 the herbarium of the United States Department of Agriculture, I 

 came across this same fungus on a ^q-w leaves among specimens 

 determined as PJiyllosticta pirina Sacc. and collected by M. B. 

 Waite at White Sulphur Springs, W. Va., and A. R. Blakely at 

 Springdale, N. C, in 1889.

Qrout's Mosses with Hand-Lens and Microscope"^ 



Part IV. of Mr. Grout's " Mosses with Hand-Lens and Micro- 

 scope " equals the previously-issued parts in good type, excellent 

 paper, and numerous, clear illustrations. More detailed expla- 

 nations might well be given some of the full-page plates, remarks 

 are too often included in the generic and specific descriptions, and 

 the descriptions could be more readily compared if the same 

 arrangement were regularly used ; however, the " non-technical " 

 character of the book as announced on the cover page is un- 

 doubtedly the author's justification for his treatment of the sub- 

 ject. Numerous short keys are given ; these with the excellent 

 illustrations should make the identification of our common mosses 

 a very simple matter.
