an apparently unnamed Gloeosporium from the cranberry, Vac- 

 cinium macrocarpum ; G. elasticae Cooke & Massee, from the 

 leaves of the rubber plant, Ficus elastica ; a form from the locust, 

 Gleditschia triacanthus, which does not appear to have been re- 

 ported before ; one from Ginkgo biloba, also not heretofore re- 

 ported ; Colletotrichum gossypii Southw., from cotton ; and C. 

 Lindemuthianum (Sacc. & Magnus) Bri. & Cav., from the culti- 

 vated bean." The one from the apple only has its ascogenous 

 form reported heretofore. The authors used in the cultures ster- 

 ilized corn meal, 75° to 50° F. Referring to the fact that forms 

 occurring on dififerent hosts have been generally regarded as 

 different species, they say their study "leads to the conclusion 

 that they cannot be successfully segregated as species on mor- 

 phological grounds." They use the name Glomerella rufomacu- 

 lans (Berk.) Spauld. & v. Schrenk. 



Hasselbring, Heinrich. |m ^ 



In the Botanical Gazette for April, 1907, this author dis- 

 cusses "Gravity as a Form-Stimulus in Fungi." He experi- 

 mented with Polystictus cinnabarinus, Schizophyllum cummune, 

 and some species of Corprinus. He says in conclusion, "it fol- 

 lows from the foregoing observations on three widely separated 

 forms of the Basidiomycetes, that although gravity has no effect 

 on the organization of the hymenophore, it has a marked influ- 

 ence on determining the configuration of the fruit-body of some 

 forms. This effect is most marked in the more primitive forms, 

 which are thereby shown to be the more plastic. In the more 

 highly differentiated forms [Coprinus] this effect of gravity dis- 

 appears." 



Stevens, F. L. 



A Rust found in North Carolina on Melothria pendula, 

 "Puccinia on Melothria," Botanical Gazette, April, 1907, is named 

 P. Melothriae Stevens n. sp., accompanied with outline figures 

 of the spores. It belongs to the Leptopuccinia type. 



Smith, R. Greig. 



Dr. Smith reports a "Gelatin-hardening Bacterium," which 

 was isolated during the bacteriological examination of the tis- 

 sues of Schinus mollis, the specimen of which was exuding small 

 quantities of a torquoise-colored gum resin. To the new species 

 the name of Bacillus indurans has been given. This report is 

 found in the proceedings of the Linnean Society of New South 

 Wales, 1905, Part 2, August 30th.
