 BACTERIA, AND MYXOMYCETES

FUNGI 



773. Atwood, Alice C. Errors in Lindau's "Thesaurus" and Saccardo's "Sylloge." 

 Mycologia 12: 169-171. 1920. 



774. Bailey, M. A. Puccinia malvacearum and the mycoplasm theory. Ann. Botany 34: 

 173-200. 1920. — A brief summary of the essential aspects of the mycoplasm hypothesis is 

 followed by a detailed outline of the results obtained by Eriksson in his investigations of 

 the rust of hollyhock. The writer's own results in his experiments with this same organism 

 are then contrasted with those of Eriksson. He finds himself in marked opposition to the 

 observations and deductions of the latter worker. He finds that the tendency of the pro- 

 mycelium in this species to break up into "oidia" rather than to form normal sporidia is merely 

 the result of environmental conditions, and can be noted especially when the teleutospores are 

 completely submerged. His experiments are discussed in detail, and the results are given in 

 tabular form. He describes the apparatus which was used to insure freedom from outside 

 infection, and discusses critically every aspect of his experimental work. — H. M. Fitzpatrick. 



775. Jackson, H. S. New or noteworthy North American Ustilaginales. Mycologia 12: 

 149-156. 1920. — The bunt of rye, hitherto unreported from U. S. A., was detected in a collec- 

 tion made by L. M. Underwood in New York, 1892. It is determined as Tilletia Secalis and 

 considered distinct from T. Tritici. T. Hold is reported on species of Notholcus from Oregon. 

 Entyloma Collinsiae is reported from Oregon on two new hosts, Collinsia grandiflora and C. 

 tenella. From the same state Urocystis Trillii sp. nov. is described on Trillium chloropetalum. 

 Collections on Quamasia hyacinthina from Indiana and Q. quamash from Oregon are assigned 

 to Urocystis Omithogali. Tubercina Trientalis is reported on a new host, Trientalis latifolia 

 and from a new locality, Oregon. Because of morphological differences as well as different 

 genera of hosts attacked Cintractia axicola minor Clinton is raised to specific rank, C. minor 

 (Clinton) comb. nov. Cerastium oreophilum, Silene Watsoni and Stellaria Jamesiana are 

 reported as new hosts for Sorosporium Saponariae. Tolyposporium Iresine is described and 

 the new combination Thecaphora Iresine (Elliott) is made. Tolyposporium Junci is reported 

 for the first time from North America; two Oregon collections on Juncus bufonius are recorded.

776. Killerman, S. Fund von Polyporus montanus Quelet in Bayern. [Discovery of P. 

 montanus in Bavaria.] Hedwigia 61 : 1-3. 1 pi. 1919. — A large (60 cm. diam.) polypore was 

 found at the base and on the large roots of the "big fir" at Waldhaus, in the Bavarian forest. 

 A description and illustrations are presented. Critical comparison with described species 

 leads to the conclusion that it is P. montanus. — D. Reddick. 



111. Krieger, LOuis C. C. Field key to the genera of the gill mushrooms. Chart (17 X 

 28 in.) with 8 pages of text. The Norman Remington Co. : Baltimore, 1920. — Chart is printed 

 in black on white paper, and is folded into a small, pocket-size, press-board covered booklet 

 containing eight pages of explanatory matter. It is designed for field use, but can also be 

 used as a wall chart. The principal genera of the Agaricaceae are included, and an attempt 

 has been made to furnish an illustrated key which will enable the novice to determine the 

 generic position of mushrooms as they are collected in the field. Genera known to contain 

 poisonous species are indicated. — H. M. Fitzpatrick. 



US. Murrill, W. A. Another new truffle. Mycologia 12 : 157-158. 1 fig. 1920.— Mate- 

 rial collected by Dr. C. L. Shear in Maryland and first studied by Dr. H. W. Harkness 

 is described as Tuber Shearii Harkness, sp. nov. — H. R. Rosen.
