82 SUMMARY OF CURRENT RESEARCHES RELATING TO 



about a delicate septation of the spores, and in the same medium (lemon- 

 juice neutralized by caustic soda with gelatin) the septa persisted in new 

 generations ; they disappeared when the nutritive medium was changed. 

 They found in the culture, club-shaped muriform bodies formed which 

 they have termed " macrosporioide," from their resemblance to Macro- 

 sporium or AJternaria spores. These have also been observed in cultures 

 of Phoma Richardise. 



Studies of the Schweinitz Collection of Fungi.* — C. L. Shear 

 and N. E. Stevens publish a second contribution on this subject. 

 Schweinitz's herbarium passed to the Academy of Natural Sciences, 

 Philadelphia, at his death in 1834. Since that date various fungologists 

 have worked at the collections, and the writers of the paper here give an 

 account of these men and the results of their labours. They also trace 

 the Schweinitz specimens that were sent to other workers. These are to 

 be found at Berlin, Kew, Paris, and Upsala. A bibliography of papers 

 referring to Schweinitz is appended. 



Mycological Notes, f — Three sets of these notes have been issued 

 recently by C. G. Lloyd, each prefaced by information concerning some 

 active fungologist, with a photograph. The first indicates the branch 

 of f ungological work undertaken by J. Barton Cleland, an Australian 

 botanist. In the pages following, the genus Cytharia is discussed, a 

 small but peculiar genus of Ascomycetes, found so far only in South 

 America and Australasia. Notes are also given oli some peculiar 

 Xylarise and on some Basidiomycetes from South America or from 

 Australia. 



In the second pamphlet there is a sketch of Spegazzini and his work 

 on the fungi of South America, and an account of various little-known 

 genera and species from AustraHa, Africa, Japan, etc. 



The third series gives a photograph and some few details as to the life 

 -and activity of Karsten, who died recently. He collected over practically 

 the same region as Fries. This series of notes deals mainly with South 

 African and Austi'alian fungi, and includes the description of a new 

 genus, Pyrenopolyporis, a Pyrenomycete that simulates a Polypore. 



New or Noteworthy Fungi. f — John Dearness gives a descriptive 

 iist of fifty microfungi from various regions of North -West America. A 

 ■considerable number are new to science. The list includes both parasites 

 and saprophytes. 



A further contribution of new Japanese microfungi is published by 

 T. Tanaka.§ He describes four species, Massaria moricola, M.japonica, 

 Mycosphserella Horii, PhyUosticta ciiricola, all of which grow on living 

 material and cause more or less of disease. 



Natal Fungi.ll — Averil Maud Bottomley has revised and issued a list 

 of the fungi collected by J. Medley Wood. The specimens, amounting
