754 SUMMARY OF CURRENT RESEARCHES RELATING TO 



bushes affected with Glmosporium Ribis. In the summer of 1908, all 

 the bushes in Baden were badly attacked by this fungus, and the leaves 

 decayed and fell by the middle of .July. He found that the quantity of 

 sugar, sap, ash, etc., was much lower in a given quantity of berries 

 from diseased trees, but the quality was not seriously altered. 



Mycological Notes, No. 32.*— C. G. Lloyd gives a sketch of the life 

 of Elias Fries, and some information as to the work done in mycology 

 and kindred subjects by his family. He reviews the American species of 

 fungi in the Fries' herbarium at Upsala, many of thorn sent by 

 Schweinitz, and makes notes on a number of the specimens. 



Penicillium glaucum as a Cause of Pellagra.f — A. Sturli has 

 tested the poison-producing power of this fungus as a contribution to the 

 solution of the pellagra problem. This disease, which attacks the 

 peasants in the Mediterranean region as well as in Austria, is due to eat- 

 ing diseased maize, and Penicillium glaucum, as the commonest fungus, has 

 been suspected. Sturli found that the fungus cultivated on Raulin's solu- 

 tion was very poisonous for rabbits. The poison is neither a phenol, an 

 acid, nor an alkaloid. 



International Nomenclature.}— P. A. Saccardo publishes a note on 

 the question of nomenclature as applied to Cryptogams, and quotes with 

 modified approval the decision of the Moscow naturalists that mosses 

 should have as their initial date 1782, the date of Hedwig's work ; algfe 

 and lichens should refer back to Linngeus' Species plantarum, 1753 ; 

 and fungi to Fries' Systema Myeologicae, 182!). Saccardo reviews more 

 recent authors, and enumerates the genera of fungi created by Persoon 

 and others, which form the basis of all present-day work. 



Plant Diseases. — A. Eichinger§ writes on the skin disease of potatoes 

 caused by Spondylocladium atrovirens. He failed to detect any rotten- 

 ness caused by the fungus. When the tuber was directly infected, the 

 fungi germinated and then died down, but when pieces of the fungus 

 were placed on bits of the potato, the mycelium penetrated the flesh. 

 The author does not consider that the fungus has any connection with 

 Rhizoctonia violacea. A series of observations were made on the sen- 

 sitiveness of this fungus to light during the growth period. 



V. Ducomet || finds a new species of Fusarium on Lolium italicum ; 

 Sphserella pinifolia on living needles of pine, and Vermicularia varians 

 on stems, roots, etc., of Solatium nigrum and Physalis peruviana. He 

 describes their development and the changes induced in the tissue of the 

 host-plants. Ducomet adds notes on oak mildew. 



J. Gr. (Irozeubacherf found that Sphserella citrullina and its pycnidial 

 form Ascochyta citrullina was causing a disease of melons in Geneva
