84 SUMMARY OF CUIUIENT RESEARCHES RELATING TO 



recorded on any of the higher plants. Biological notes are given in 

 many instances — short descriptions of the effect produced by the parasite, 

 etc. A. L. S. 



Mycological Notes. V.— W. B. Grove {Journ. Bot., lOin. 59, 

 13-17). Notes are given on various species, Boydia inscnlpta Pucciiiia 

 Peucedmii-parisiensis and Phomopsis abietina, the latter a parasite on 

 Pinus silvestris and Psendofsuga Douglasii, reported as causing great 

 harm on the Continent, and a source of possible danger to home 

 conifers. A. L. S. 



Macrosporium ?oot-rot of Tomato. — J. Rosenbaum {Pliijto- 

 patholofpj, 191^0, 10. 415-22, 4 figs.). The author has suggested Foot- 

 rot as a suitable name for this disease, seeing that the trouble is mainly 

 visible at the base of the plant ; the stalks turn brown where they 

 emerge from the soil, and the fungus causing the disease spreads both 

 up and down. Plants are attacked at all ages both in the seed bed and 

 in the field, and the disease has caused considerable logs in Delaware. 

 Many cultures and inoculations were made, and the fungus was finally 

 identified as Macrosporium Solani E. & M. A. L. S. 



Pythium Disease of Ginger, Tobacco and Papaya. — L. S. Subra- 

 MANIAM {Mem. Df'pt. Auric. India, l'J19, 10, 181-94, 6 pis., 3 col.) 

 The disease, which attacks not only seedlings but the base of trees, is 

 caused by a new species oV Prjthium.. P. Bnfleri. The author gives an 

 account of experimental cultures and inoculations and suggests methods 

 of treatment. ^ A. L. S. 



Mycological Notes. — C. (I. Lloyd {Cincinnati, Ohio, 192o, No. 02, 

 904-44, 16 pis.). A portiait and chronological arrangement of the 

 principal events of J. C Arthur's career opens the present series of 

 notes. Several genera of fungi are described, the species of which 

 are criticized and figured. Among these are Cordyceps, Thamnomyces, 

 Alevrodiscus, Echinodothis, etc. There are also historical and structural 

 notes of many other somewhat obscure species. A. L. S. 



Mycological Notes.— C. G-. -Lloyd (Cincinnati, Ohio, 1920, No. 63, 

 945-84). The author begins these notes by calUng attention to an 

 article on Fungi in the " National Geographic Magazine " by Ij. C. 0. 

 Krieger. It is illustrated by sixteen coloured plates and thirty-six 

 photographs. Both styles of illustration are ©f very high quality. 

 Lloyd also remarks on the death of P. A. Saccardo and bears testimony 

 to his great work on Fungi. The bulk of the notes deals with letters 

 from correspondents and the fungi sent by them from all over the 

 world. A. L. S. 



Fungi from the Polish Trenches. — S. Killermax {Hedwiyia, 

 1917, 59, 220-33, 1 fig.). The collection was made by a theological 

 student who served in the war. The fungi were chiefly collected during 

 the summer of 1916 in the virginal forest near Lida. Drawings made 

 by the collector enabled Killerman to determine many of the species, 

 mostly Basidiomycetes, and some of the larger Ascomycetes. There is 

 one Myxomycete determined, Ceraiiomyxa mucida. A. L. S.
