Dissemination and Naturalization of Certain Marine Algae. — 

 C. Sauvageau {Bull. Inst. Oceanoijr. Fomln. Prince de Monaco, 1918, 

 No. 34-2, '2d) pp.). A discussion of the gradually enlarged distribution of 

 certain well-known species, their means of transport, and the difficulties 

 thej encounter. The species discussed are Gijstoselra (jranulata, Alarkt 

 esculenta, which are probably drift-weed, and Golpomenia siniwsa, 

 Lammaria Lejolisii and Bonnemaisonia hamifera, which are chance 

 emiorants and probably transported by some ship. The invasion of 

 Golpomenia sinuom is likened to that of Elodea canadensis in the 

 mischief they both cause. Certain forms, Himanthalia lorea^ Gystoseira 

 concatenata and Sarqassum vidgare appear unable to acclimatize them- 

 selves to the conditions in the Gulf of (lascony, though frequently 

 brought there. E. S. (x. 



Notes on Algae New to Japan.— Kichisaburo Yendo {Bot. Mag. 

 Tokyo, IDls, 32, 65-<sl, 175-87). Concluding chapters. The number of 

 alg^ treated in this series of papers amounts to 178 species, varieties and 

 forms ; and the author suspects that several more epiphytic and parasitic 

 species have yet to be added to the list. In the final chapter he 

 discusses questions of synonymy and distribution. It is interesting to 

 find that 'dH marine alg^ are common to Japan and Europe ; also that, 

 by careful study of the living plants, 39 species of Sargassum have been 

 reduced to 19. An index to the genera and species wiiich are discussed 

 in the scattered series of papers is provided. A. 0-. 



Fungi. 



Blepharospora terrestris (Sherb.) Peyr. — B. Peyronel {Atti 

 Real. Accad. dei Lincei, 1920, ser. 5, 29, 194-7). The fungus here 

 described was found to be causing serious damage to plants of Lrqnnus 

 alb us. The author found that the roots of the plants were specially 

 affected, and in the cells he found the characteristic phycomycetous 

 hypbffi and a few oospores. He was also able to observe the formation 

 of zoospores and later their germination. The fungus was placed in 

 Phytophthora by Sherbakoff, but, according to Peyronel, its place is in 

 the above genus. A. Lorrain Smith. 



Large Pyrenomycetes. II. — C. G. Lloyd {Gincinnati, Oltio, 1919, 

 17-32, 23 figs.). Lloyd gives a synoptic key to seventeen genera of 

 this group. He selects a few of these for special note : Kretzschmaria^ 

 a tropical genus, with stems bearing heads that become confluent ; 

 Daldinia, of which only one species, D. concentrica, is common. A new 

 genus, Garnostroma, has been established by Lloyd ; the species G. thyrsus 

 has a stem 6-8 in. long with a conical fleshy stroma at the apex ; 

 Penzigia, Sarcoxylon and Olaziella, all rare genera, are figured and 

 discussed. A. L. S. 



Life-History of Ascobolus magnificus. — B. 0. Dodge {Mycologia, 

 1920, 12, 115-34, 2 pis., 28 figs.). This fungus, originally from Porto 

 Rico, has been kept in culture by the author for several years. He
