Kellerman, W. A., Cultures of Puccinia Thompsonii Hume. 

 (Journal of Mycology. X. p. 173, 174.) 



Puccinia Thompsonii Hume is proven by inoculation experiments 

 identical with Puccinia bolleyana Sacc, P. atkinsonia Diet!.. and 

 P. sambuci (Schw.) Arth. The following synonymy is given: 



Puccinia sambuci (Schw.) Arthur. Aecidium sambuci Schweinitz. 

 Puccinia bolleyana Saccardo. Puccinia atkinsonia Dictl. Puccinia 

 thompsonii Hume. Hedgcock.

RiCKER, P. L., Notes on Fungi I. New or Interesting 

 American Uredineae. (Journal of Mycology. X. p. 165 

 — 167.) 



Mention is made, with descriptive notes, of the following fungi: 

 Puccinia arundinariae Schw. on Arundinaria sp. in Texas; Puccinia 

 burnetti Griff, on Eriocoma cuspidata Nutt. in Nevada; Puccinia 

 crandallii Pamm. and Hume on Festuca kingii in Montana, Oregon, 

 and Wyoming; Puccinia cynodontis Desm. on Cynodou dactylon in 

 Florida; Puccinia deformata B. and C. on Olyra latifolia L. in Porto 

 Rico; Puccinia haleniae Arth. and Holway on Gentiana calycosa 

 Griseb. in Wyoming; Puccinia obscura Schroet. on Juncoides cotnosum 

 in Oregon. Aecidium williamsi Ricker sp. nov. is described on the 

 leaves and stems of Lithospermum angustifolium Michx. at Brookings 

 S. D This species is not related to Puccinia lithospermi E. and K., 

 which proves to be Evolvus pilosus Nutt., the Aecidium of which is as 

 yet undescribed, although it has -been collected. Hedgcock. 



Salmon, Ernest S., Mycological Notes. 1. Formation 

 of Ascospores in Erysiphaceae, 2. Mycophagous Larva e. 

 (Journal of Botany. Vol. XLII. June 1904. p. 182—185.) 



1. The author describes several infection-experiments which prove 

 that the ascospores of Erysiphe graminis DC. are able directly they are 

 formed, to germinate and infect host-plants. It is possible, therefore, 

 that under favourable circumstances E. graminis may pass through its life 

 cycle more than once in the course of a year. It is pointed out that 

 the manner in which ascospores are produced in E. graminis is 

 exceptional, and that it is possible that in other species the ascospores 

 may require a period of rest before germination. 



The conidial stage of E. graminis and E. Polygoni are recorded as 

 occurring during December and January. 



2. The author reared examples of the Larvae feeding on the conidia 

 of various species of Erysiphaceae. The flies obtained belonged to the 

 Dipterous Order Cecidomyidae, and on being submitted to Abbe 

 Kieffer were determined as being species of Mycodiplosis Rubs. 



A bibliography on the subject of Mycophagous Larvae is 

 appended. A. D. Gotton.
