Some of the fungi which have been employed in this wOrk 

 are the red-headed fungus, Sphaerostilbe coccophila Tub, the 

 white-headed fungus, Ophionectria coccicola Ellis and Everh., 

 the black fungus, Myriangium Duriaei Mont., the yellow fungus 

 of the whitefly, Aschersonia flavo-citrina P. Henn., the red 

 fungus of the whitefly, Aschersonia Aleyrodis Webber, and the 

 brown fungus of whitefly, which bears no scientific name. The 

 fungi here named have been known for years and used success- 

 fully, but, to ensure success, observations and treatment must be 

 conducted with care. The material for use in connection with 

 this kind of work is supplied by private parties. 



A later publication by the same author on the subject of " Fungi 

 Parasitic upon Aleyrodes citri" has been prepared as a thesis 

 at the State University of Florida. This account records two 

 other species of fungi, V erticillium heterocladum Penz., and 

 Microcera sp., which are parasitic on Aleyrodes citri R. & H. 

 and on scale insects. 



In an article by J. Lagarde on "Conditions biologoques et 

 repartition des champignons dans le massif de V Aigoual" (Bull. 

 Soc. Myc. de Fr. 24: 197-220. 1909), the author deals with 

 the difficult and interesting question of the distribution of the 

 higher fungi as determined by the character of different locali- 

 ties, which are grouped as follows: (1) Cultivated valleys, (2) 

 chestnut and oak woods, covering the lower mountain slopes, 

 (3) coniferous woods, especially those planted in pine, (4) beech 

 woods, on the higher slopes, (5) wet ravines, (6) pastures and 

 other exposed places not under cultivation. 



A list of species is given for each of these groups, and the 

 habitats of many of the species are discussed. In the cultivated 

 valleys are found, Agaricus campestris, Panaeolus papilionaceus, 

 several species of Coprinus, Schizophyllum alneum, Coriolus 

 versicolor, etc. A much longer list is given for the chestnut and 

 oak woods, species of Amanita, Lactarius, Russula, Boletus and 

 Tricholoma being prominent. Amanita caesarea is cited as being 

 adapted, like the chestnut, to sandy soil, or soil free from lime, 

 and conditions of moderate temperature and humidity. Wood- 

 destroying species are discussed briefly.
