development of soil Hymenomycetes, while Salix alba was without any. 

 Betula alba is accompanied by a certain number ; under Alnus glutinosa 

 a Lactarius was constant ; Alnus viridis was without characteristic soil 

 fungi. These and other facts are discussed, and the writer concludes 

 that soil Hymenomycetes abound in connexion with trees and other 

 plants that harbour mycorhiza, and that they are absent from the non- 

 mycorhizal plants. He finds in this a proof that mycorhiza for the 

 most part is a fungus belonging to the Basidiomycetes. 



Bermuda Fungi.* — Fred. J. Seaver contradicts the statement that 

 few fungi occur in Bermuda, though he admits that the larger Basi- 

 diomycetes are not so abundant as in other regions. Thirty-two species 

 of these have been determined. A fairly long list is published of other 

 fungi collected and determined in which the Funni imperfecti and the 

 Ascomycetes bulk largely. Among the latter are four new species 

 belonging to Ascophanus, Nectria and Calonectria. About 150 species 

 were collected during a two weeks' visit to the islands, but many of them 

 are still undetermined. 



New Japanese Fungi. — A. Yasudaf describes a new species, Poli/- 

 sf ictus nipponicus, a small plant of imbricate growth, white above, though 

 becoming brown when dry, with minute pores and globose small spores. 

 The new species was collected from the trunks of trees. 



A new TheUphora is also described by Yasuda.| It is very similar 

 to T. papulosa Lloyd, but differs in the smooth dark colour of the 

 upper surface. 



Takewo Hemmi § gives a list of new microf ungi parasitic on Japanese 

 plants, mainly on the leaves. Species of Crasterosporium Septoglaum, 

 Septoria and Armatella are included. There is no mention of any 

 serious damage done to the plants attacked. 



Yasuda || also describes an Ascomycete, Leotla japonka sp. n. It 

 somewhat resembles L. atrovirens, but is a much larger plant. It grew 

 on damp soil. 



African Microfungi.lf — R. G. Fragoso lias published a list of micro- 

 fungi collected by D. A. Caballero at Melilla (Marruecos). They are 

 all minute parasites on economic or other plants. The species 

 Sphserahna maroccana on I'rifolium Boccotii, and 3IicroiUplo(Ua iridicola 

 on Irisftlifolia, are new to science. 



New or Noteworthy Fungi.**— C. G. Lloyd publishes descriptive 

 and critical notes on many unusual species of fungi from all over the 

 world. Several Polyporeae and allied genera, such as Irpex and Lenzites,
