464 SUMMARY OF CURRENT RESEARCHES RELATING TO 



of considerable interest. In general, he found in the Basidiomycetes 

 that, although gravity has no apparent effect on the organisation of the 

 hymenophore, it has a marked influence in determining the configuration 

 of the fruit-body of some forms. This effect was most marked in 

 primitive forms. In highly-differentiated forms such as Coprinns no 

 formative influence of gravity could be observed. The organisation of 

 the fruit-body depended largely on internal causes, or on stimuli not 

 sulficiently understood. 



Flora Italica Cryptogama.* — A second part of this work, continuing 

 the description of the Pyrenomycetes, has been issued by Traverse. The 

 Sphffiriacese are divided according to spore forms into Allantosporas, 

 Hyalosporae, and Phfeospors. Twenty-eight genera with their species 

 are described, and each genus is illustrated by figures in the text. 



Fungi from Northern Latitudes.f — E. Rostrup has worked out the 

 fungi collected by H. It.. Simmons on the second Norwegian Polar 

 Expedition, Is08-r.)u2, on the ' Fram.' He makes a list of 80 species, 

 most of them from Ellesmere Laiul. They are nearly all parasitic or 

 saprophytic on Phanerogams. Eight species are new to science.
