Jan. 1908] Notes Jrom Mycological Literature 35 



Fink, Bruce. 



Cladonia bacillaris, CI. macilenta, and CI. didyma are de- 

 scribed and discussed in the September No. of the Bryologist: 

 "Further Notes on Cladonias, XII." Illustrations natural size, 

 also magnified two or three diameters, are given of Cladonia 

 bacillaris and CI. macilenta. 



Arthur, J. C. 



In the Journal of Mycology, September 1907, Dr. Arthur 

 makes his seventh report, "Cultures of Uredineae in 1906." He 

 calls especial attention to the experimentally unravelled life his- 

 tory of the Rust which inhabits flax, remarking of this study of 

 the serious menace to successful flax growing that "it greatly 

 clarifies the problem of controlling the flax rust in the interest 

 of the cultivator." Of selected materials after tests, 48 collections 

 were available belonging to three species of Rusts, exclusive of 

 the aecial pine rusts, and from these 223 sowings were made. 

 Also 53 sowings were made with Caeoma and Peridermium 

 spores from pine, all without infection, 27 sowings with telio- 

 spores of Gymnosporangium, and 23 sowings with various aeci- 

 spores. That is, 324 sowings were made, and 134 species grown 

 temporarily in the greenhouse were used as hosts. The tabulation 

 of negative results, and repetitions of previous work is extended 

 — and in that connection a new species is described, namely 

 Uromyces effusus. We take space to reproduce the summary 

 for species here reported for the first time: i. Melampsora 

 LiNi (Link) Desmaz. — Teliospores on Linum. usUatissimum L,. 

 sown on L. Lervisii Pursh and L.usitatissinium L. 2. Uromyces 

 SiLPHii (Syd.) Arth. — Teliospores on J uncus tenuis Willd. 

 sown on Silphium perfoliatum L. 3. Gymnosporangium Nel- 

 SONI Arth. — Teliospores on Juniperus scopulorum Sarg. sown on 

 Amelanchier canadensis (L.) Medic, and Sorhus americana 

 Marsh. 



Fink, Bruce. 



Illustrated and discussed are Cladonia cristatella and Cla- 

 donia coccifera in "Further Notes on Cladonias, XII," The Bry- 

 ologist for November, 1907. The first named species is a dis- 

 tinctly North American lichen ; the second is known in all the 

 grand divisions except Africa. 



Hebden, Thomas. 



A list of fourteen species is given, "Some British Columbia 

 Lichens" (Rossland, B. C), in the November Bryologist, 1907.
