570 SUMMARY OF CUEEENT RESEARCHES RELATING TO 



been occasioned by Phytophthora. Bacterial maladies are also discussed, 

 and the parasitism of Fusarium solani. He considers that this fungus 

 is nearly always saprophytic, and only penetrates the tubers in excep- 

 tional conditions which render them more susceptible. He gives advice 

 as to the treatment for the various diseases. 



Mycological Notes.* — Franz v. Hohnel finds that Stictis Tilm and 

 Platyghca nigricans are identical with Achroomyces Tilm, a fungus 

 parasitic on Tilia. He founds a new genus, Korydanella, on a hymeno- 

 mycete collected by him on pine-wood. Another new genus, Debar yella 

 (Hypocreaceaj), was parasitic on Valsa scabrosa ; the spores are colour- 

 less, fusiform, four-celled. The author adds notes on several other 

 fungi ; he thinks that a number of Sphreriaceaj with stroma forms, such 

 as Cryptospora and Gryptosporella, ought to be classed with the Hypo- 

 creaceas. 



Fungi of Alaska.f — William Trelease writes the preface to a list of 

 Alaskan fungi determined by P. A. Saccardo, C. H. Peck, and himself. 

 The first fungus from the region was a Dothedia, recorded many years 

 ago by Hooker and Arnott ; since then there have been small additions 

 to the list, followed now by the descriptions of species collected in the 

 Harriman expedition. There are many new species, and an index to 

 the various hosts of the parasitic forms is supplied, along with a record 

 of the various substrata on which fungi were found growing. The 

 plentiful vegetation of Alaska and the frequent rains make it probable, 

 Trelease thinks, that a very large fungus flora exists.
