Pitcci/iia Polygoni-alpini, and Sphacelotheca alpina. The latter destroys 

 the flower ; a second species was detected on the leaves of the same host. 



Study of Anthracnoses.* — 0. W. Edgerton limits this term to the 

 fungi that at one stage form a GUeosporium. In many cases the perfect 

 fruit form is knowu, but not in all. The author includes Coll etotric hum 

 as a synonym of Glozosjjorium : the difference between the two he does 

 not consider of generic importance. He describes the development of 

 GlcBOsporium and then its different forms as it appears when associated 

 with different ascogenous fungi. He takes first the Gnomonia type, and 

 gives an account of G. veneta with the pycnidial stage Glaosporium 

 nervisequum, which is parasitic on sycamore and oak. The Pseudopeziza 

 type was first worked out by Klebahn, and his work is referred to. 

 Most of the work was done by Edgerton on the Glomerella type : the 

 perfect stage, one of the Pyrenomycetes, was found to be extremely 

 variable both from the same and from different hosts. It is doubtful if 

 they represent different species or only forms — thus two forms were 

 found on the apple : one from the north, the other from the south, that 

 from the south alone producing perithecia. In artificial cultures very 

 considerable variety was also produced, but the author deprecates the 

 use of these characters in the determination of species as being generally 

 too variable. A full bibliography of the subject is given.
