ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 749 



New Fungi from South America.* — C. Spegazzini has recently 

 issued papers on new fungi, including many new species and genera. 

 The first is devoted to parasites on Theobroma cacao, where he finds one 

 new genus Hysteriopsis (Hysteriaceae) with muriform spores. 



In a second paper f he describes a number of Pyrenomycetes and 

 Sphasropsideae collected by A. Usteri in San Paulo ; the new genera are 

 Dimerosporiella, Hyalotheles, Dimeriella, Phceodimerklla, Eudarluca, 

 Lonchospermella, and Phceoseptoria. Many of the plants described are 

 parasites, and the name of the host has been omitted. 



In a third paper J he gives the parasitic fungi of Ilex para// uayensis, 

 72 in number, most of them new species, with the following new genera : 

 (Pyrenomycetes) Acanthonitschlcea and Phccobotryosphceria ; (Disco- 

 mycetes) Stilbopeziza ; (Fungi imperfecti) MacrodiplodieUa, Phceo- 

 marsonia, and Spermatoloncha. 



Mycothecea of the School of Pharmacy. XXVIII. — G. Bainier§ 

 continues his studies of filamentous fungi : he finds that the mould, 

 which he described as Cephalomyces nigricans, should be placed in the 

 genus Cephaliophora. The species of the genus inhabit warm countries, 

 but can easily be cultivated in the laboratory. Descriptions and plates 

 of those already described are added. 



He describes || also a mould, Haplographium fuscipes, which has been 

 recorded on leaves of Scotch pine, and was found by him on decaying 

 leaves of Epicea excelsa. The genus resembles the brown form of 

 PenkilUum, and many of the species have been found on leaves of 

 Conifers. Bainier gives a careful description of the mould, and of the 

 cultivations of it that he made. 



Diseases of Plants. — 0. Falladaif gives a review of diseases of 

 sugar-beet due to parasitic fungi ; in Italy there was an attack of the 

 plants by Cercospora beticola. In other places Phoma Petce was signalled, 

 though not always the cause of the drying up of the beet. CJadosporium 

 herbarum and Clasterosporium putrefaciens occurred frequently, and 

 seriously affected the quantity of sugar in the beet. 



T. Petch** records the diseases of tobacco in Dumbara ; he finds a 

 Cercospora and an Oidium on the leaves, and a somewhat serious root 

 trouble caused by a species of Fusarium. 



In West Virginia the apple trees suffered badly from loss of leaf. 

 J. L. Sheldonft has examined into the cause of this, and finds it to be
