Grove, W. B„ New or Noteworthy Fungi. Part. IV. (Journ.

Osborn, J. G. B., Preliminary observations on the Mil- 

 dew of Grey Cloth. (Journ. Econ. Biol. VII. p. 58—63. 3 figs. 

 June 1912.) 



A preliminary investigation of the mildew of cotton-goods which 

 occurs when in störe or in transit. Cultures from infected material 

 gave rise to a variety of fungi and bacteria; and the author states 

 that, when the conditions are favourable, these feed upon the size 

 which is used in the preparation of the cloth. Of the conditions, 

 moisture is probably the most important. A. D. Cotton. 



Ramsbottom, J., Workpublished during 1911 on the cyto- 

 logy of fungus reproduction. (Trans. Brit. Myc. Soc. III. 5. 

 p. 354-365. 1911.) 



More than a dozen papers on the cytology of fungi appeared 

 during 1911. The writer gives a useful summary of this work, 

 and treats the more important papers in some detail.

Rea, C, British Geasters. (Trans. Brit. Myc. Soc. III. 5. p. 351 — 

 355. 3 col. pl. 1911.) 



Rea has made a special study of the Geasters, and gives here 

 a running commentary on the British species. He accepts the 3 

 genera Myriostoma, Astraeus, and' Geaster and proposes a fourth viz 

 Fornicatus. The 3 coloured plates, and critical observations add 

 greatly to the value of the paper. A. D. Cotton. 



Rea, C, New or rare British Fungi. (Trans. Brit. Myc. Soc. 

 III. 5. p. 376—380. 1 col. pl. 1911.) 



All the larger fungi added to the British fiora during 1911 are 

 chronicled, and in addition some notes on rare species are given. 

 Phoeotremetta pseudofoliacea Rea (gen. nov.), and Heliotium chloro- 

 podium, Rea and Ellis are described as new and figured.

 A. L. Sm. (Trans. Brit. Myc. Soc. III. 5. p. 331-332. with figs. 1911.) 



The plant described by Phillips as a liehen, Spinctrina caespi- 

 tosa, is show from an examination of the original material to be a 

 fungus, and is re-described under the above name. It oecurred on 

 decayed Polypoms and is regarded as an alien. A. D. Cotton.
