paludosa and also C. sphagnicola (Am. & Perss.) Warnst. hie now regards as synonyms of 

 C. tenuis (Aust.) Evans. He recognizes the validity of C. fissa (L.) Raddi and also of C. 

 Muelleriana Schiffn. (as represented by Schiffner's No. 609), referring C. adscendens (Nees) 

 Warnst. to the latter species as a synonym. He likewise maintains that the North American 

 C. Sullivantii Aust. is amply distinct from C. arguta Mont. & Nees. — A. W. Evans.

 The author describes new forms of Sphagnum rubellum Wils., S. plumulosum Roll, and S. 

 aquatile Warnst., and also the following new varieties: S. obesum Wils. var. devoniense Sherrin 

 & Wheldon and S. hercynicum Warnst. var. Binsteadii Wheldon. The latter variety is 

 figured. — S. H. Burnham.

 carpa (Schimp.) Broth.; it was collected by Brothers Leon and Hioram in the province of 

 Pinar del Rio, Cuba. — E. B. Chamberlain.

616. Behrens, J. Die Perithecien des EichenmeUtaus in Deutschland. [The perithecia 

 of oak mildew in Germany.] Zeitschr. Pflanzenkrankh. 31: 108-110. 1921. — Oak mildew has 

 attracted considerable attention in Europe since 1907 and, although the leaves are abundantly 

 covered with conidia, perithecia are rare. Records show that Arnaud and Foex found peri- 

 thecia at Cavillargues, France, and were enabled thereby to identify the mildew with the 

 American oak mildew, Microsphaera quercina (Schw.) Barr. In 1920 the author discovered 

 a group of perithecia on a single oak leaf near Hildesheim, Germany. Subsequent comparison 

 showed the form found in Germany to be the same as that in France. — H. T. Giissow.

 der Ascomyceten 1918. [Remarks on H. Klebahn, Perfect and imperfect fruits of Ascomycetea 

 1918.] Hedwigia 62: 38-55. 1920. — The sources and merits of Klebahn's work are con- 

 sidered and a critical consideration from the point of view of recent taxonomic studies of 

 ascomycetes is given. The author states that Klebahn obtained his measurements partly 

 from dry material imbedded in balsam and partly from material soaked in water. Since dry 

 material gives from 25 to 50 per cent smaller measurements than wet tissues, he thinks that 

 Klebahn's results must be taken with due allowance. He gives differences between Klebahn 

 and other authors for measurements of perithecia, asci, ascospores, and conidia, and then 

 passes to a critical discussion of the treatment of Mycosphaerella, which he considers at length 

 regarding the relationships between perfect and imperfect forms, and the bearing of the 

 various fruit forms on the disposition of genera and species. The genera Carlia, Epiploca, 

 Gnomonia, Entomopeziza, Fabraea, Pseudopeziza, Trochila, and Gloeosporium are discussed 

 with respect to their validity and certain of their species. Klebahn's disposition of genera 

 and species is frequently criticized. — Bruce Fink.
