Murrill, William A. 



Under the title "A new Chestnut Disease," in the September 

 No. of Torreya, a full account is given of a disease found on 

 living, or recently killed branches of the American chestnut 

 caused by Diaporthe parasitica Murrill n. sp. — specimens known 

 from Bronx Park, New York City, New Jersey, Maryland, the 

 District of Columbia and Virginia. The heretofore known species 

 of Diaporthe are not parasitic. Text figures illustrate the new 

 species. 



Wilson, Guy West. 



Three fungi are referred to in "Mycological Notes from 

 Indiana" in Torreya, September 1906, namely, Peronospora floer- 

 keae Kellerm., Hydrogera kleinii (van Tiegh.) Kuntze (Pilobo- 

 lus kleinii van Tiegh.) and Stamnaria americana Massee & Mor- 

 gan. 



Ricker, P. L. 



An admirable paper is "A list of known Philippine Fungi," 

 given in the Philippine Journal of Science, i :277-2-4, Sept. 15, 

 1906, by P. L. Ricker. He says it should not be regarded as a 

 critical revision of the species, but only an attempt to bring to- 

 gether all references to species credited to the Archipelago by 

 various authors. New species are Phyllachora merrilli Ricker 

 n. sp. on leaves of Ficus sp. ; Nummularia philippinensis Ricker 

 n. sp. ; Trematosphaeria palaquii Ricker n. sp. on bark of Pala- 

 quium latifolium ; Stereum luzoniense Ricker n. sp. ; and The- 

 lephora diamesa Ricker n. sp.

 County, Massachusetts," Bryologist, Sept. 1906, Mr. Howe re- 

 ports 24 species not included in the Lichens attributed to said 

 County by Messrs. L. L. Dame and F. L. Collins. 



Kellerman, W. A.

 is described a disease of the Century Plant (Agave americana) 

 found in Guatemala ; the species, P. williamsoniana, is described, 

 followed by a translation of the diagnosis into Latin. Journal of 

 Mycology, September 1906. 



Arthur, J. C. 



This is a descriptive notice — published in the September 

 No. of the Journal of Mycology, 1906 — of Dr. Arthur's paper 

 on Fine Klassifikation der Uredineen (read before the Interna- 

 tional Botanical Congress at Vienna in July 1905), "A new clas- 

 sification of the L^redinales." The purpose is to state some of 

 the aids and difficulties that will beset the practical acceptance 

 of the classification.
