86 SUMMARY OF CURRENT RESEARCHES RELATING TO 



photographs and descriptions are given of a number of little known 

 forms such as CJathrus Treubii and Simblum yrucile, both from Java. 

 Lloyd publishes a request for undeveloped eggs of Lysurus borealls. 

 He gives an account of the Gastroinycetes of Schweinitz's Herbarium, 

 correcting the determinations of specimens in several cases. In No. 30, 

 the Phalloids of Japan are dealt with, including the genera Phallus, 

 Mutinus, Lysurus, and Latemea. Additional notes on Lysurus Gardnerii 

 and Anthurus aserceformis are given. Lloyd prints photographs of the 

 homes of A. P. Morgan and of Linnasus, with a portrait of the former. 



Handbook of Fungi.*— There bas recently been issued from the 

 British Museum a new edition of the Guide to Sowerby's Models of 

 Fungi. The book claims to be only a description of these, some 200 in 

 number, but it forms a good introduction to the field-study of the 

 larger fungi, as the models represent largely the more familiar and 

 conspicuous forms. Special attention is paid throughout to tbe cooking 

 properties, the main object of the models being to enable people to 

 distinguish between edible and poisonous species. A glossary of 

 technical terms is added. 



Book of Garden Pests.t — P. Hooper Pearson has issued a useful 

 handbook of fungoid and insect pests that infest cultivated plants. 

 The plants are divided into sections of miscellaneous garden plants, 

 fruit trees, and vegetables, and arranged alphabetically. Under each 

 plant are recorded the fungi and insects that cause diseases, with short 

 accounts of each and the most practical methods of dealing with them. 

 A full account is given of insecticides and fungicides. The book is 

 well illustrated by drawings and photographs, and forms one of a series 

 of Handbooks of Practical Gardening-.

Plant Diseases 4 — As many Baldwin apples are marred by the 

 presence of fruit spots, Charles Brooks has made a study of the subject, 

 and finds that the spotting is due to a fungus, CyJindrosporium pomi 

 sp. n. Tbe fruits are attacked in July or early in August, probably 

 from spores developed on apples that may have lain on the ground all 

 winter. If the apples are infected at an early stage the fungus is cut 

 off from the apples by a layer of cork cells, forming a barrier to its 

 f urther development. If the attack supervenes later, when the apples are 

 more mature, the fungus develops rapidly and causes the browning and 

 drying of the host tissue. Spraying with Bordeaux late in June or early 

 in July is recommended. 



Ugo Brizi § reports on samples of grain sent for examination to the 

 Agricultural School of Milan. He had noted the low percentage of 

 germination and tbe poor growth that resulted from sowing the seed. 

 The grains were, to outward appearance, healthy, but microscopic 

 examination showed the presence of fungal mycelium which had 

 probably gained entrance at an early stage of seed development. 

 Cultures determined the fungus to be AsperyiUus fumiyatus. Brizi
