Miss A. C. Atwood, Cataloguer, Bureau of Plant Industry, 

 Washington, D. C„ contributes the following: 



" In the course of my work I have chanced upon several rather 

 important errors in Lindau & Sydow's Thesaurus Litteraturae 

 Mycologicae et Lichenologicae to which the attention of users of 

 this work ought to be called. 



In vol. i, p. 377, are several references credited to Alb. H. 

 Dietrich : the first, no. 80, should be credited to Dietrich, Albert, 

 (1795-1856) and the others no. 81-83, to Dietrich, Heinrich 

 August. 



In vol. 2, p. 42, a large number of references are credited to 

 Elie Marchal : nos. 11-24, 32, should be credited to Marchal, Elie; 

 nos. 31, 33-56 to Marchal, Emile. No. 38 is a wrong reference, 

 no such article appearing in vol. 20 of Rev. Mycol., it is probably 

 the same as no. 25a. 



Under Cornu, Maxime, vol. 1, p. 311, no. 77 is a reference 

 to Comptes Rendus XC, 1880, p. 357, which would seem to indi- 

 cate that the article appeared in this volume of the Comptes 

 Rendus; the fact is, however, that p. 357 contains only a note of 

 the reading of the article, which never appeared in the Comptes 

 Rendus. 



I have spent some time in trying to locate this article and 

 think it may, perhaps, be worth while to record here the informa- 

 tion which I have gathered in regard to it. It appeared in a work 

 published under the auspices of the Paris Academy under the 

 title Observations sur le phylloxera. Paris, 1881. Cornu's part 

 in this work was entitled Etudes sur les peronosporees and the 

 article Le meunier, maladie des laitues &c. forms part I of this. 

 In a note, Cornu states that brief resumes of this memoir were 

 published in the Comptes Rendus v. 87, p. 801-803 and p. 916-919, 

 from which we may infer that these two articles Maladies des 

 laitues nominee le meunier (Lindau, v. 1, p. 311, no. 60) and 

 Maladies des plantes determinees par le Peronospora (Lindau 

 v. 1, p. 311, no. 61) formed the basis for his later article. Etudes 

 sur les peronosporees II. Le peronospora des vigncs was published 

 in 1882 by the Paris Academy, Cornu's title being used as a sub- 

 title under the general title Observations sur le phylloxera, which 

 latter is quoted by Lindau (see p. 321, no. 88). I cannot discover 

 that these articles of Cornu appeared in any other form."
