May 1906] Notes from Mycological Literature 
133 
years, the writer proposes to close the series of preliminary 
diagnoses which he has issued from time to time since 1899.” 
Dr. Thaxter has described about 500 species in all including 
about 48 genera. In this last paper about thirty new species are 
described. Nine of them are North American. 
Annales Mycologici for Feb. 1906 (Vol. IV, No. 1) has 
the following table of contents: Blakeslee, Albert Francis, Zygo¬ 
spore Germinations in the Mucorineae; Sydow, H. et P., Neue 
und kritische Uredineen — IV; Freeman, E. M., The Affinities 
of the Fungus of Lolium Temulentum, L.; Oertel, G., Eine neue 
Rhabdospora-Art; Elenkin, A. A., Species novae lichenum in 
Sibiria arctica a cl. A. A. Birula-Bialynizki collectae (expeditio 
baronis Tol) ; Krieger, W., Einige neue Pilze aus Sachsen; 
Heinze, Barthold, Sind Pilze im Stande, den elementaren Stick- 
stoflf der Luft zu verarbeiten und den Boden an Gesamtstick- 
stoff anzureichern ?; Rehm, Ascomycetes exs. Fasc. 36; Sac- 
cardo, P. A., Mycetes aliquot congoenses novi; Neue Literatur; 
Referate und kritische Besprechungen. 
H. et P. Sydow Neue und kritsche Uredineen — IV. in 
Annales Mycologici for Feb. 1906 (4:28-32) publish a dozen 
new species mostly from North America and the Philippines. 
The American species are Uromyces amoenus, U. amphidymus, 
U. fremonti, U. heterodermus, U. substriatus, Puccinia fuchsiae 
and P. aemulans. 
A report of the investigation done under grants as re¬ 
search assistant of the Carnegie Institution, by Albert Francis 
Blakeslee, is published in the Annales Mycologici, 4:1-28, Feb. 
1906. It consists of an exhaustive study of Zygospore Germi¬ 
nations in the Mucorineae. A lithographic plate accompanies 
the paper, illustrating Phycomyces nitens. 
E. M. Freeman read a paper before the Mycological 
Society at New Orleans on the Affinities of the Fungus of 
Lolium temulentum L., whibh is published in Annales Mycol¬ 
ogici, 4:32-4, Feb. 1906. In this lie refers to the discovery in 
1895-6 by Frank Maddox of Tasmania that in loose smut of 
wheat an infection of the grains could be produced by placing 
spores on the ovary at flowering time. The grains so infected 
were apparently normal, but from them smutted plants were pro¬ 
duced in the following year. Brefeld, and also Hecke, in 1903-4, 
rediscovered the same method of infection in case of loose smut 
of wheat and of barley smut. The author has previously pointed 
out the strong probability that the fungus of Lolium temulentum 
was a smut. Now he suggests that the recent discoveries of the 
infection method as stated above strengthen considerably the 
theory of its smut origin.
