L70 SUMMARY OF CURRENT RESEARCHES RELATING TO 



of Craterellus from Labrador named by the writer C. borealis. It, i- 

 a small species of cream-buff colour, and grows among moss. 



Under Gyphella he describes 21 species, some of them well known 

 in Europe, but a number of them confined to America and new to 

 science. Most of them are minute species ; those newly described are 

 figured. They range in diameter from a fraction of a millimetre for 

 the smaller, to 5 to 15 mm. for the larger species. They grow mostly 

 on dead twigs or herbage, and can only be distinguished from Pezizse 

 by microscopic examination. 



Parasitism of Hymenochsete agglutinans.* — This fungus is com- 

 mon in the Eastern United States, where it is indigenous. It grows 

 normally on alder trees, and often surrounds twigs or branches, cementing 

 two or more together. A. H. Graves describes an instance in which 

 a part of a large spice bush Benzoni sestivale was firmly bound to a 

 dead alder stem by the fungus, and was killed. Death was due more to 

 strangling than to parasitism, though after the stem is weakened the 

 fungus begins to prey on the tissues. 



Enumeration of Philippine Basidiomycetes.f — G. Bresadola and 

 H. Sydow gives a list of larger fungi from these islands, mostly Polyporei 

 or allied families. It is rather remarkable that the large bulk of the 

 collections should be known plants. Only two are recorded as new 

 species ; Hymenochsete subferruginea and H. deflectens. In most cases 

 the name of the province and the collector are given with the date of 

 collection. 



New or Rare Spanish Fungi. J — R. G. Fragoso publishes a con- 

 tribution of microfungi to the Spanish Flora. He has found Uromyces 

 Rum iris on Rum ex A cetosella, and suggests that the rccidia may be found 

 on Ficaria. Other species of Uredineas are accompanied by descriptive 

 notes. There is a new species of Sphaeropsideae, Phomopsis Paui, 

 found on dead stems and branches of Xantlrius spinosus. The author 

 considers that it may be the imperfect form of Diaporthe Xanthii which 

 grows on the same host-plant. Of the 24 species listed, 20 are new for 

 Spain . 



Plant Diseases. — E. S. Salmon § publishes certain biological obser- 

 vations on the American gooseberry mildew. He suggests that only the 

 perithecia that are formed in summer attain maturity : those formed 

 later do not hibernate, as they never mature. Spring infection would 

 be from those earlier formed, which pass the winter . on the ground or 

 on the branches.
