grows on bogs, but there is no attempt at cultivating it. The natives 

 search for it eagerly, and consider it a great delicacy. 



Larger Fungi of Rhine-land.* — A first list of Agarics is published 

 by Gustav Herpell, and instructions are given as to collecting and pre- 

 serving species. Herpell has had great success in preparing and mounting 

 specimens for the herbarium, and at first he advised against their poison- 

 ing. He now finds that the preparations are liable to be attacked by 

 insects or by moulds, and he considers it necessary to poison them with 

 a 2 p.c. solution of mercuric chloride in methylated spirits (90 p.c). 

 With this solution he paints the back of the gelatin paper on which the 

 fungi are pressed, and further he paints over the specimens with cellu- 

 loid varnish. Herpell describes the natural features of the locality in 

 which he collected the fungi. He gives notes as to habitat, etc., and 

 with each species the size of the spores. 



German Fungus-flora.f — W. Migula continues his work on the fungi 

 of Germany. He begins the third section with a discussion of the 

 Basidiomycetes, which he considers under two divisions, the Hemi- 

 basidii and the Eubasidii. The Hemibasidii include the UstilaginaceEe ; 

 the Eubasidii are subdivided into two great groups, the Pro to basidio- 

 mycetes and the Autobasidiomycetes. 



Migula has already finished his description of the Ustilaginaceaa and 

 has begun with the Protobasidiomycetes, the first order being the Ure- 

 diuales or rust fungi. The genera are illustrated by coloured or by 

 black and white plates. 



Mycological Notes.J — Franz v. Hohnel continues his notes and criti- 

 cisms on systematic mycology, with special reference to species occurring 

 in Java. Many new species are described, and the following new genera : 

 Koorrfersiella and Loranthomyces (Sphajriaceas) ; Coccoidella and Disco- 

 dothis (Dothideaceas) ; Trichopeltopsis, near to Dimerosporium ; Scliiff- 

 nerula (Englerulaceaj) ; Myxasterina, near to Aster ina • Micropoerella 

 ( Spheroid eas) ; Japonia (Excipulaceas) ; Araneomyces (Tubercularieas) ; 

 and Strumellopsis (Tubercularieae dematieas) ; the last a parasite on leaves 

 of Vaecinium. Notes on some Myxomycetes are also added. 



Atlas of Fungi. § — L. Rolland has for some time been issuing 

 coloured plates of fungi of France, Switzerland, and Belgium. As the 

 series is finished, he has issued in pamphlet form descriptive notes of 283 

 species, represented on 120 plates. The first pages discuss the larger 

 fungi, generally explaining the method of classification and the structure 

 of these plants. Particular attention is paid to locality and time of 

 growth, and to the edible or poisonous nature of those described. 



Poisonous and Edible Fungi. || — F. Gueguen contributes the con- 

 cluding chapters to Rolland's Atlas of Fungi. He gives descriptions 

 of poisonous species, with an account of the symptoms of poisoning.
