described, and the behaviour of the plant when that is impossible owing 

 to the absence of tlie conjugating hyphai. A. Loruain Smith. 



Phytophthora Meadii sp. n on Hevea braziliensis. — W. McRae 

 {Mem. Dept. Auric Tiidia, 1018, 9. 2r.)-7;5, ;> pis.)- The disease caused 

 by the fungus manifest? itself as fruit-rot, an abnormal leaf-fall, and 

 a rot of the tapped surface. The author gives a full description of the 

 development of the fungus itself ; he finds that fertilization is similar 

 to that described by Pethybridge in P. enjthroseptica : viz. that the 

 oogonial branch grows through the antlieridium. McRae contrasts 

 the fungus wi4:.h Phytopltthora Faheri on Cacao fruit, and describes the 

 points in which they differ. He discusses the dissemination of the fungus, 

 the loss sustained by growers, and the preventive measures that are 

 advisable. A. L. S. 



Galactinia amethystina (Phill.) Wakef. — E, M. Wakefield {Tram. 

 Brit. M/jcol. Soc, l'.)20, 6, pt. 4, 375). The species here described has been 

 published as Ascoboh/s amethystimis by Phillips and later as Galactinia 

 Phillipsii by Boudier. The specific name amelhystinm^ has therefore 

 been restored. It is characterized by its deep purple colour and by the 

 purple-coloured spores. A. L. S. 



Pyronema Isetissimum Schrot. from Silesia. — A. Lingelsheim 

 {Hediviijia, I'JIG, 58, ir)3-5, 1 fig.). In a full description of the fungus 

 the author gives notes on the colouring substance of the hyph;©. He 

 concludes that it belongs to the Carotin group, which has been found 

 in other fungi, UredineiB, Pezizacete, etc. A. L. S. 



Rare Pezizacese from Bavaria. — S. Killerman {Hedwigia, 1917, 

 59, 234-5). Killerman records the finding of Pyronema leetissimum 

 in early spring. He compares it with Peziza pluvialis and Pyronema 

 domesticum. Several other known species were found. A. L. S. 



New Locality for Sarcosoma globosum. — S. Killerman {Hed- 

 wigia, 1918, 59, 313-8, 2 figs.). The author gives a full description 

 of the fungus and of the habitat among moss in fir woods. He found 

 it in Bavaria. A. L. S. 



Mycological Contributions : I., Ascomycetes. — K. Boedyn and 

 C. VAN Overeem {Hedwigia, 1918, 59, 307-12). The authors found 

 a brightly coloured Humaria, in which they determined the colouring 

 substance as a Carotinoid. They describe the fungus as Humaria 

 carota sp. n. They found Carotin crystals also in Ascophanus pinicola 

 sp. n. A. L. S. 



Ascomycetous Fung-i of Human Excreta. — Charles B. Fairman 

 {Lyndonville, New York, 1920, 1-11, 1 pi. 3 figs.). The author 

 discusses the various fungi that have been identified as occurring in 

 excreta. He calls attention to the difficulty of determining isolated 

 spores. A list has been drawn up by him of Ascomycetous forms, 

 fifteen of which have been described at various times. The author gives 

 a figure and description of a new species, Cylindrocolla fsecalis (Hypho- 

 mycete). A. L. S.
